PortaSens III Gas Leak Detector from Analytical Technology
The ATI PortaSens II has been updated to the PortaSens III portable gas leak detector. The new PortaSens III is a rugged hand held device used to detect leaks of toxic or otherwise dangerous gas and also to detect oxygen displacement. The D16 quickly adapts to measure different gases by inserting the appropriate gas sensor module which retains all of the calibration and configuration settings for the target gas. An internal pump with a flexible wand is included for point sampling around suspect pipe fittings and confined spaces. Readings and settings are presented on a backlighted, resistive touch, color graphics LCD with a beeper to notify you of alarms and other events. Readings are recorded in .csv files (ASCII text, comma-separated values) and transferred to a PC using the supplied USB cable. No external application is required. The files may be opened with any text editor or directly by applications like Microsoft Excel. Power is provided from a rechargeable NiMH D-cell battery. The battery should be removed and charged in an external charger after each use. The battery is not used or even required when the device is connected to a USB port. The inlet port, located on the manifold lid, is fitted with a quick disconnect fitting to connect the flexible want. The wand can be used for probing closely around pipes and fittings and for sampled confined spaces without entering. The wand is lined with Teflon and is inert to nearly all vapors and gases. Flexible tubing may be connected to the inlet port to sample high gas concentration or those beyond the reach of the wand. Fluorocarbon based tubing is strongly recommended for measuring low concentrations of reactive gases. Other materials may be used for high range measurements where the adsorption of gas by the tubing is negligible or where you are probing or significant leaks. The internal walls of the wand and any inlet tubing must be kept dry. Water on the walls may absorb soluble gases and decrease the gas readings, presenting an unsafe condition. If the inside of the wand or tubing gets wet, dry dry air through it for 10-15 minutes.

Features

  • Interchangeable smart sensors for over 30 gases
  • Internal sample pump and external sampling wand
  • One hand pistol grip design
  • Easy to read back lit color graphics, LCD

Series B14 - Gas Detection System Controller

The Series B14 Receivers are compact electronic modules that provide local alarm, display and signal retransmission functions for gas detection systems. The modules are designed to accept input from either two, three or four wire 4-20 mA transmitters. The transmitters can be located up to 10,000 feet from the receiver. They are ideally suited for use with ATI’s toxic or combustible gas transmitters.

Features

  •  The Model B14 alarm receivers are DIN rail mounted modules that can be supplied in single or multiple unit enclosures.
  • Gas concentrations are indicated directly in ppm, ppb, percent or percent LEL with the display range selectable by the user.
  • Each module provides separate caution, warning, and alarm setpoints with LED bar indicators of each alarm point. LED indicators flash on initial alarm condition and change to steady on when the alarm is indicated.
  • Modules contain individual relays for each alarm setpoint. However, each relay can be assigned to any setpoint to allow multiple alarm functions at a single alarm point. Relays are configurable for either standard or fail safe operation and for either latching or non-latching operation.
  • A fourth LED alarm bar and relay are provided to indicate trouble conditions. The trouble alarm and relay will activate on loss of input signal or it the 4-20 mA input drops below a specific value.
  • Isolated input contacts are provided to allow an unpowered switch input for acknowledgement of alarm conditions from a remote location or via telemetry equipment.
  • Modules provide a 24 VDC power supply to operate either 2 or 3 wire transmitters
  • A 4-20 mA output is provided from each module, optically isolated from the input signal to avoid ground fault problems.

Gas Sample Pump for Fixed Point Systems from Analytical Technology

A21 Sampling Systems use a high quality diaphragm pump operated by a brushless DC motor to provide continuous sampling over long periods of time. Sampling pumps are rated for over 10,000 hours of continuous operation and diaphragms in the pump may be changed easily if necessary. The pump will draw samples against a vacuum of up to 10″ Hg for sampling negative pressure duct systems when necessary. In addition to the sampling pump, A21 systems contain various components needed to insure reliable sample measurement. A flowmeter mounted on the front panel allows the user to adjust the sample flowrate to the desired value, normally around 500 cc/min. Internal to the system is a loss of flow detector that will warn of sampling system problems that could compromise the gas measurement system. A loss of flow alarm light on the front panel provides local flow loss indication while an internal relay can be used to indicate this alarm remotely.

Installation

Monitoring gas levels using a sample draw system requires that the installation be done carefully and that the nature of the target gas be considered. In general, it is best to locate the gas sensor on the vacuum (inlet) side of the sample system. This insures that the gas sample will be measured before contacting pump or flow detection components that might affect gas concentration. This is especially important when sampling for reactive gases such as chlorine, sulfur dioxide or acid gases.

The type of tubing used on the portion of the sampling system between the sample point and the inlet port of the gas sensor is another important consideration. Reactive gases require the use of Teflon or other fluorocarbon tubing, while non-reactive gases can be samples using flexible PVC tubing. Sampling from gas streams saturated with moisture may require heated sample tubing, and the effect of condensation on the gas sensor must be carefully evaluated.

For fastest response, gas sampling lines between the sample point and the inlet to the gas sensor should be kept as short as possible. Sample transport time depends on the internal diameter of the sampling tube used as shown below. Values are based on a flowrate of 500 cc/min.

1/8″ id (3mm) tubing 29 second per 100 feet
3/16″ id (5mm) tubing 65 seconds per 100 feet
¼” id (6mm) tubing 116 seconds per 100 feet

Series D12-IR Combustible, Carbon Dioxide or Nitrous Oxide Gas Transmitter

ATI’s Series D12 gas transmitter product line has been expanded. Now available in this versatile package is an LEL transmitter utilizing an Infrared sensor that resists the poisoning problems inherent in catalytic bead sensors. The D12-IR utilizes a compact IR sensor in a corrosion resistant housing with sintered flame arrestor to meet hazardous area classification requirements and is suitable for most plant environments.

The D12-IR gas transmitter eliminates the poisoning problems inherent in catalytic bead sensors. While catalytic LEL sensors offer reliable service, the presence of silicon vapors, hydrogen sulfide and halogenated hydrocarbons can quickly degrade sensor performance. Infrared sensing technology is not susceptible to these potential interferants which means greater measurement stability and longer sensor life.

The D12-IR transmitter can also be configured with Infrared sensor for carbon dioxide (CO2) or nitrous oxide (N20) detection. All sensor versions can operate in diffusion mode for ambient air or with a flow cell for pumped samples.

The D12-IR is available in four configurations:

  •  For measurement and data transmission to remote display and alarm equipment, the D12-IR operates in 3 wire mode. Integral LCD indicates gas concentration as well as alarm conditions
  • Transmitter with HART for plants operating with HART protocol communications systems, the D12-IR can be supplied with this option. The HART output supports both 4-20 mA and constant current mode of operation.
  • Transmitter with integral relays for systems requiring local alarm functions or systems where discrete outputs are desired, the D12-IR can provide 3 relay outputs. Relays are assignable to any alarm setpoint or fault condition and are fully programmable for setpoint, hysteresis and time delay.
  • When RS-485 communication is desirable, D12-IR transmitters with alarm relays can be supplied with a Modbus interface. software supports up to 247 unique addresses for large system use.

Features

  •  Infrared sensing element is protected inside a stainless steel assembly with a sintered stainless steel flame arrestor.
  • Because the IR sensor is always in an active state, the transmitter continuously monitors critical sensor functions and indicates any sensor problems both on the display and through the analog output.
  • D12-IR transmitters can be factory calibrated for volumetric methane measurements in special applications. Ranges from 0-10%, to 0-100% by volume are available. A separate sensor is also available for high percent level measurements of heavier hydrocarbons such a butane and propane.
  • Each time a sensor is zeroed or spanned the data is stored in memory. Calibration history can be recalled and sensor condition reviewed by operating personnel when necessary.
  • Optional relays outputs can be used for local alarm functions. All relays are programmable for setpoint, hysteresis, on-delay, off-delay and other variables. Even a remote reset feature is provided for in the transmitter design.
  • Transmitter analog output can be set to user definable values. This provides for complete loop testing without the need to apply gas to the sensor
  • Alarm relays may be activated on command to allow testing of local alarm devices. Any combination of relays may be activated based on operator selection. Output and alarms may also be inhibited for maintenance and calibration.
  •  The transmitter is available with either HART or MODBUS protocol. The HART protocol supports the HART Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS protocol supports 9600 baud access to concentration and status information and supports alarm setup and many other functions on either RS485 or RS232 (software selectable). Comes with a register/tag database on a 3 1/2″ diskette.
  • Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. A back light is available.

Ozone Calibration Gas Generator

The use of ozone gas is increasing rapidly in a wide variety of applications, such as water treatment, odor control and food processing. As the number of ozone generators in use has expanded, the need for gas leak detection near the generators or at ozone application points has expanded. And with expanded use of ozone leak detectors has come the need for a tool to generate the low level ozone gas needed to calibrate ozone sensors.

ATI’s Model A23-14 is a portable generator designed to produce an ozone gas concentration below 1 ppm, which can be used for detector calibration at almost any location. The generator uses a compressed air cylinder to supply dry air to an ultraviolet cell where ozone gas is formed. The resulting flow of air with a small amount of ozone exits the generator cell through fluorocarbon outlet tubing that is used to deliver the ozone standard to a gas sensor.

Operation of the ozone gas generator is very simple. The UV generator cell is plugged into any convenient power outlet and the valve on the air cylinder is opened. The cylinder valve is a fixed flow regulator so that no flow control is required. The outlet tubing from the generator is connected to your ozone gas sensor for whatever period is needed for calibration and then the system is shut off. Generator output is nominally around 0.8 ppm, but each generator is individually marked with an accurate ozone gas concentration value measured prior to shipment.

Ozone generators are supplied in a durable molded case with sufficient space for outlet tubing and calibration adapters. The basic kit contains the generator, one 103 liter air cylinder with fixed flow regulator and 3 feet of outlet tubing.

Series D12 Digital Gas Detection Transmitter from ATI

Series D12 Digital Gas Transmitter from Analytical Technology features loop powered transmission, loop powered with HART, transmitter with integral relay or a transmitter with MOBUS. Gas detection systems come in all shapes and sizes. Some require simple 4-20 mA transmission. Some are better suited to local alarm relay functions. Some relay require both. And increasingly, digital communication directly to the transmitter is desirable. Not to mention the fact that self-testing sensor capability adds to the reliability of any system.

We could not come up with a catchy name that would convey all the capabilities of the D12, so we’ll just explain everything our transmitter can provide – starting with our four different configurations.

Features

  • For measurement and data transmission to remote display and alarm equipment, the D12 will operate in 2-wire mode (except for combustible gas). Integral LCD indicates gas concentration as well as alarm conditions.
  • Loop powered with HART for plants operating with HART protocol communications systems, the D12 can be supplied with this option. Our HART output supports both 4-20 mA and constant current mode of operation.
  • Transmitter with integral relays for systems requiring local alarm functions, or systems where discrete outputs are desired, the D12 can provide 3 relay outputs. Relays are assignable to any alarm set point or fault condition and are fully programmable for set point, hysteresis and time delay.
  • When RS-485 communication is desirable, D12 transmitters with alarm relays can be supplied with a MODBUS interface. Software supports up to 247 unique addresses for large system use.
  • Operating functions such as calibration, alarm setup, alarm reset, data view and setup options are all available using a magnetic tools. It is not necessary to open the enclosure when making adjustments.
  • Measured gas values are stored at user definable intervals and can be recalled when needed on the LCD display. Data can be downloaded using MODBUS interface.
  • Gas concentrations are display in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. a backlight is available when operating in 3 wire mode.
  • Program settings stored in the transmitters may be protected by a user selectable 4-digit password. Operators may still review all functions, but changes may only be made by authorized personnel.
  • The D12 electronic assembly plugs easily into the power supply board in the base of the enclosure. Transmitters can be removed for wiring and quickly replaced in the event of a fault condition.
  • Transmitters are designed for operation in hazardous areas. The case aluminum housing for the D12 transmitter is rated for Class 1, Division 1, Group B, C, D locations and is UL, FM and CSA certified.
  • The output range for a particular sensor is programmable within the range boundaries set in that sensor.
  • Optional relay outputs can be used for local alarm functions. All relays are programmable for set point, hysteresis, on-delay, off-delay and other variables. Even a remote reset feature is provided for in the transmitter design.
  • Transmitter analog output can be set to user definable values. This provides for complete loop testing without the need to apply gas to the sensor.
  • Alarm relays may be activated on command to allow testing of local alarm devices. Any combination of relays may be activated based on operator selection. Output and alarms may also be inhibited for maintenance and calibration.
  • The transmitter is available with either HART or MODBUS protocol. The Hart protocol supports the HART Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS protocol supports 9600 baud access to concentration and status information and supports alarm setup and many other functions on either RS-485 or RS-232(software selectable).

Sensor Flexibility

No matter which style of transmitter you choose, your D12 transmitter includes features that enhance performance and provide operational flexibility, starting with out own advanced electrochemical sensors.

  • Every toxic gas transmitter will accept up to 46 different sensors, greatly reducing the need for multiple transmitter models. The self aligning sensor holder simply plugs in, with automatic sensor recognition and verification when contact is made.
  • Plug-in sensors store calibration data, allowing sensors to be calibrated separately from the transmitter. This allows bench calibration (or factory calibration) of sensors to reduce the necessity for carrying calibration gas around the plant. Sensors are even interchangeable with ATI’s C16 PortaSens II portable gas detector.
  • Each time a sensor is zeroed or calibrated, the data is stored in sensor memory. Calibration history can be recalled and sensor condition reviewed by operating personnel whenever necessary.

Sensor Response Verification

For many toxic and combustible gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to insure system integrity.

  • Sensor response is verified with an actual gas sample, generated on demand. Electronic sensor and circuit tests just cannot provide the same level of confidence.
  •  Auto-Test gas generators are easily installed and removed when necessary. Generators store run time information accessible to operators and are automatically tested for compatibility with the installed sensor.
  • Systems using the Auto-Test generators store a testing log indicating the number of tests performed as well as test results. This data is stored in individual sensor memory for later review.

Series F12 Digital Gas Detection Transmitter from ATI

The Series F12 Gas Transmitter is an Intrinsically Safe (IS) version of ATI’s explosion proof D12 transmitter. In its standard form, it is designed for detection of a variety of toxic gases in hazardous area applications requiring IS devices. In addition, it is also well suited for all general purpose applications where toxic gas measurement is required. For IS installations, this transmitter is also available with a Hart communication option.

F12 Transmitter use ATI’s standard smart sensors for maximum flexibility. Sensors are easily exchanged and contain all calibration constants in sensor memory, eliminating the need for field calibration of transmitters. Sensors may be calibrated on the bench and then simply plugged into the transmitter. Calibration data is read into the transmitter automatically and no other adjustments are normally required. For general purpose gas detection applications, the F12 transmitter is also available in Non-IS versions. One version provides for easy interface to RS-485 networks using a standard MODBUS communication protocol. A second version provides a complete AC powered instrument with 3 alarm relays (SPST) available for external alarming.

Features

  • Transmitter are designed for use in application requiring intrinsically safe devices for safety purposes.
  • Every transmitter will accept up to 45 different sensor modules, greatly reducing the need for multiple transmitter models.
  • Gas generators permanently installed on the sensor verify sensor operation by providing a bump test of the sensor from daily to once a week.
  • Plug in sensors store calibration data, allowing sensors to be calibrated separately from the transmitter. This allows bench calibration (or factory calibration) of sensors to reduce the necessity for carrying calibration gas around the plant.
  •  A non-IS version of the transmitter provides 3 integral alarm relays. Relays and programmable for setpoint, hysteresis, on-delay and other variables. Systems with alarms are available for operation from 12-30 VDC supplies or from 115 or 230 VAC power.
  • The IS version of the transmitter is available with Hart communications. The Hart protocol supports the Hart Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The non-IS versions of the transmitter are available with MODBUS communications. The MODBUS protocol supports 9600 baud access to concentration and status information and supports alarm setup and many other functions.
  • Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters.
  •  Measured gas values are stored at user designable intervals and can be recalled when needed on the LCD display. Data can be downloaded using a Hart or MODBUS interface.
  • Each time a sensor is zeroed or calibrated, the data is stored in memory. Calibration history can be recalled and sensor condition reviewed by operating personnel whenever necessary.
  • Operating functions such as calibration, alarm setup, alarm reset, data view and setup options are all available using sealed front panel switches on the face of the Nema 4X transmitter enclosure.
  • For use in applications where condensation is a problem, this heater option keeps the sensor above the whew point to eliminate loss of sensitivity due to moisture blockage on the sensor face.
  • Transmitter analog output can be set to user definable values and relay outputs can be set to specific states for complete simulation of detection system operation. Output and alarms may also be inhibited for maintenance and calibration.

A14/11 Economy Modular Gas Detection System from Analytical Technology
GasSens is a flexible component system providing a variety of options to meet individual gas detection and alarm requirements. Economical and low maintenance, this system is your best choice for reliable leak detection. GasSens detection systems consist of individual modules that can be located where required. Sensor/transmitters located in the area where gas leakage or buildup might occur, provide the basic measurement for the system. Sensor transmitters are available in either NEMA 4X or explosion-proof versions and can be supplied with ATI’s exclusive Auto-Test automatic sensor testing system. Receiver modules provide the electronic brains for the detection and alarm system. Each compact module includes a digital display of gas concentration, isolated analog output, and 4 relay outputs. Receivers may be located up to 1,000 feet from sensor/transmitters for remote indication or can provide local control functions such as valve shut off while transmitting a 4-20 mA signal to remote displays or dataloggers. Receiver modules provide an interface between the detection system and external alarming and data logging requirements. One module is used with each sensor/transmitter.

Features

  • The LED display Indicates gas concentration directly in ppm, ppb or %. The display may be operated in high intensity mode for outdoor use or in normal mode for indoor application
  • An isolated 4-20 mA output is standard. The output will drive loads up to 1,000 ohms for use in recording, data logging or computer input.
  • Two alarm setpoints are factory adjusted to standard values but may be set to any value from 5% to 100% of range. Front panel LED’s marked Warning and Alarm indicate the status of each alarm setpoint. A standard alarm time delay of 2 seconds or a longer delay of 10 seconds may be selected. In addition, alarms may be switch programmed to activate either above or below the setpoint.
  • Three alarm output relays are SPDT with unpowered contacts for use in activating external signaling devices, control elements or for input to telemetry or annunciator systems. Each relay may be assigned to either alarm setpoint for application flexibility. Relays are factory set to energize on alarm, but may be switch programmed for fail safe operation. Relays may be also set either latching or non-latching operation.
  • Trouble alarm & relay should the sensor/transmitter input be lost, a trouble light (LED) on the front panel will flash and an associated relay will activate. For those systems equipped with the Sensor Auto-Test feature, this alarm will also activate if the sensor does not respond to the automated gas test.
  •  A single front panel switch marked A/R serves a number of functions. When an alarm occurs, the switch will silence an audible horn wired to the module and will change the alarm lights from flash to steady on. After the alarm condition has cleared, the switch will also activate an electronic module test, inhibit alarm contacts and activate the sensor Auto-Test.
  • Terminals are provided for connection of a remote reset switch so that alarms can be acknowledged form a remote location or through a telemetry system.
  • External electrical connections are made to plug in terminal blocks. Should module service ever be needed, modules can be replaced in minutes.
GasSens gas detection systems employ electrochemical sensors developed and manufactured by ATI. Expertise in electrochemistry and sensor design provide the foundation for leak detection systems that perform continuously with minimal maintenance. Sensors are rated for ambient temperature from -25 to 50ºC, allowing both indoor and outdoor applications. Excellent zero stability and high sensitivity and selectivity combine to make ATI sensors the best available. Gas sensors are closely coupled to a digital transmitter for excellent noise immunity and the ability to transmit long distances using unshielded cable. The transmitter is powered from the receiver module and uses a unique current pulse position technique to send information to the receiver over a two wire connection. The receiver connection in not polarity sensitive, virtually eliminating the possibility of incorrect transmitter wiring. Sensor/transmitters can be located up to 1,000 feet from receiver modules. Sensor/transmitters are housed in shielded NEMA 4X enclosures for use in almost any industrial environment and are designed to meet intrinsic safety standards. An explosion proof version is available.

Auto-Test – Savings & Safety

A major expense in gas detection systems is the cost of regular testing to ensure that sensors are responding. This requires a technician to inspect sensors weekly and apply a small amount of gas manually to check response. ATI has developed a unique system to reduce this maintenance requirement. Available on most ATI digital sensor/transmitters is an option called “Auto-Test.” This option consists of an electrochemical gas generator closely coupled to the sensor. Every 24 hours, the receiver automatically activates the generator, producing a small amount of gas that diffuses into the sensor, just as it would if a gas leak occurred. The microcomputer is the receiver analyzes the output of the transmitter to determine that the sensor is responding normally. When proper sensor response is detected, the generator is turned off and the system goes back to normal operation. If no sensor response is detected, the TROUBLE light on the receiver will flash and the trouble relay will activate. During testing, alarm relays are inhibited so that external alarms are not activated. The Auto-Test feature ensures that each sensor is regularly tested with gas. Premature sensor failure or blockage of the sensor membrane is quickly detected. In addition, self-testing will alert maintenance personnel when a sensor has reached the end of its useful life. Since sensors normally last anywhere from 12 months to over 3 years, this feature allows users to determine when sensor replacement is needed.

Power Supply Module

A compact universal power supply in a DIN rail module similar to the receiver was developed. The power supply will accept any AC or DC input from 85 to 225 volts, without adjustment. Other options include a battery back up system and horn and strobe light options.

B12 Series 2-Wire Transmitter for Wet Gas Streams

Increasingly stringent air quality requirements have led to expanded use of wet scrubber systems to control air emissions. Chlorine storage facilities and chemical process plants are frequently required to scrub exhaust gas streams to remove halogen and acid gases. Unfortunately, monitoring reactive gas concentration in moisture saturated air streams presents problems for standard diffusion sensors. Condensing water in these air lines can quickly blind diffusion sensors, rendering them inoperable. ATI’s Series B12 Wet Gas System was developed to meet the need for reliable measurements in wet scrubber outlets for other gas streams that might be saturated with water vapor. Systems have been developed for monitoring strong oxidants (chlorine, bromine, chlorine dioxide, or ozone), acid gases (HCl or HF) and hydrogen. The basic B12 Wet Gas System consists of a loop-powered 2-wire transmitter and a corrosion resistant sensor specifically engineered to operate at 100% RH. Sensors are designed for direct insertion into vent stacks or may be used in a flowcell if sample can be pumped to the sensor. When remote display and alarm relay functions are required, the B12 Wet Gas Transmitters can be connected to ATI’s B14 Alarm Receiver System. This system will provide direct digital display of gas concentration, plus 3 alarm setpoints, remote alarm reset input and retransmit 4-20 mA output. Or, the B12 transmitter may be used separately and tied directly to the users DCS, PLC or other equipment. Either way, the B12 is an excellent solution to a difficult monitoring problem.

UniSens Universal 2-Wire Transmitter

The UniSens universal 2-wire gas transmitter handles 28 different gases, providing the most economical and flexible gas measurement system available today. Time was, monitoring multiple gases meant using different gas transmitters – each with its own maintenance problems, its own appetite for spare parts, its own installation headaches and so on.

Never again, thanks to ATI. The UniSens universal 2-wire gas transmitter handles 28 different gases, providing the most economical and flexible gas measurement system available today. Combining universal electronics, bench calibration capability, automatic sensor verification, fault detection and alarming and superior sensor technology, UniSens is your best transmitter choice.

UniSens is designed for ambient gas monitoring in all kinds of industrial environments: gas storage areas, gas compressor rooms, process piping galleries, rail car sidings, analyzer shacks, gas cabinets, chemical process areas and more.

In fact, the UniSens transmitter can be used most anywhere that hazardous gas conditions might develop either through leakage or through natural build up.

ATI sensing modules consist of an electrochemical gas diffusion sensor and a solid state memory assembly. These sensors provide excellent response time, maximum selectivity and superior temperature stability for reliable gas sensing in a wide range of environments. The companion memory assembly stores operational information and calibration constants, along with gas sensor identification, sensing module range and software revision level. Complete sensing modules are housed in convenient snap-in packages that mate easily with UniSens transmitters.

This unique combination of sensor and memory lets you calibrate sensing modules with any UniSens transmitter. So instead of calibrating in the field, you can bench calibrate sensing modules with a spare transmitter; once the sensors are snapped into a field transmitter, their calibration constants upload automatically.

The UniSens microcomputer controlled transmitter provides a local digital display and a 4-20 mA analog output proportional to gas concentration. It works with any ATI sensing module, configuring its own display and output range automatically based on data read from the module’s memory. Zero and calibration data is also read into memory, so the transmitter is automatically calibrated when it’s connected to a calibrated module.

Magnetic controls on the front of the transmitter allow field calibration, manual activation of the Auto-Test feature (if installed) and review of sensing module data including gas type, range and number of successful Auto-Tests. The transmitter can also act as an analog output simulator to facilitate complete loop testing. Outputs of 4.0, 12.0 and 20.0 mA are selectable via the front panel, along with a trouble signal of 3.6 mA. The transmitter is housed in a durable cast aluminum shell with an 11 pin octal base for easy installation and removal. And since UniSens transmitter are 100% interchangeable, one unit can service as a backup for every type of gas in use.

Auto-Test – Savings & Safety

Available on many ATI sensing modules, the optional Auto-Test gas generator can cut testing costs dramatically by automatically verifying sensor response. The Auto-Test gas generator is coupled to the end of the sensor as an integral part of the sensing module. Every 24 hours, the transmitter activates the generator and monitors the sensor for response. If the sensor responds properly, the system reverts to normal operation; if it fails, output is driven to 3.6 mA to signal trouble. (During testing, the output signal is held at the pre-test value). The transmitter maintains a log of completed tests and can display the time until the next scheduled test. An operator can manually activate the Auto-Test, too.

Combustible Auto-Test Sensor

Now sensor response can be verified every 24 hours automatically. Combustible gas detectors are used in a wide variety of industrial plants to detect gas leakage or buildup before it reaches explosive levels. These detectors rely on thermal oxidation of any combustible gas or vapor on the surface of a heated catalyst. In other words, they simply burn the gas and measure the heat released in the combustion process.

While this type of sensor is generally stable and reliable, it is also subject to poisoning by silicon vapor, lead compounds and other environmental contaminants. To detect loss of sensitivity, most users test combustible sensors either weekly or biweekly to ensure response. The procedure is simple, but requires manpower to perform the test.

ATI’s Auto-Test Combustible Gas Transmitter eliminates the need for frequent response checks. This transmitter performs an automatic gas test on the sensing element every 24 hours. The result is a combustible gas detector system with a level of reliability beyond that of any other system available. This daily sensor response verification is as close to a fail-safe detection system as you can find, with the added benefit of greatly reduced manual testing.

Transmitter Features

  •  Transmitters contain an LCD display indicating LEL values locally.
  • Non-intrusive calibration using a magnetic transmitter controls allow adjustments without removing enclosure cover.
  • Manual Auto-Test -the hydrogen generator may be activated manually on command to observe sensor response, if desired.
  • The result of each Auto-Test is logged in transmitter memory. Operators may review the number of passes and fails from the LCD.
  • The 4-20 mA output from the transmitter may be manually set to 3, 4, 12 or 20 mA in order to test external alarm devices.
  • Electronic transmitters are modular, plugging into a standard relay base for ease of service.
  • Where installations require the sensor be located remote from transmitter electronics, sensor may be supplied with an explosion-proof junction box and a remote gas feed system to facilitate calibration.

Auto-Test System Operation

Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas, heating the active element and changing its resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration. As long as the active element remains in good condition, the sensor will respond rapidly to the presence of combustible gas.

The Auto-Test sensor is actually a combination of a gas sensor and an electrochemical hydrogen gas generator (patent pending) integrated into an explosion-proof stainless steel housing. When activated by the electronic transmitter, the generator produces hydrogen that diffuses to the gas sensor through the flame arrestor protecting the sensor. If the sensor responds properly, the transmitter will show a “Pass” indication. Should the sensor not respond properly, and “Auto-Test Fail” message will activate at the transmitter and the 4-20 mA output from the transmitter will drop to 3 mA, providing for remote fault indication.

Gases and hydrocarbon vapors such as methane, propane, butane, gasoline, toluene, hydrogen and many others can be reliably monitored in process buildings, analyzer enclosures, pump stations and gas compressor stations. In fact, anywhere gases or vapors may build up to explosive levels can be readily monitored using this transmitter.

C12-17 Combustible Gas Transmitters are three wire transmitters, operating from 24 VDC power supplies and transmitting a 4-20 mA signal proportional to 1-100% LEL (Lower Explosive Limit) of a particular gas or vapor. The transmitter is available either as a blind transmitter or with integral LCD display that provides local indication of gas concentration, visible through the glass window in the explosion proof housing. Units supplied with the integral display also contain a single alarm setpoint and relay for local alarm purposes. This integral is a latching alarm that can be reset with a magnetic tool without opening the enclosure.

C12-17 transmitter can be connected directly to PLC, DCS or computer based alarm systems without additional hardware. If complete alarm systems are needed, ATI can supply Series B14 modular alarm receivers or Series C14 multi-point scanning alarm units to provide all required alarm functions.

Sensor Operation

Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas, heating the active element and changing it’s resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration.

Explosion proof sensor assemblies are made of 316 stainless steel for maximum corrosion protection. A sinter bonded flame arrestor provides the gas diffusion path to the sensing elements while maintaining the flame proof integrity of the assembly. Sensing elements are specially designed for maximum poison resistance and long life in harsh industrial environments, with sensor life typically 2 years or more.

Dri-Gas Gas Sampling System

Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions. ATI has developed a solution to this problem with a gas sampling system that also conditions the sample by removing water vapor. The Dri-Gas sampling system draws gas samples from high humidity vent stacks, ducts, wet wells or other humid locations. The system removes water vapor from the gas sample by contact with a cold plate that condenses moisture and delivers a dehumidified gas sample suitable for toxic and combustible gas monitoring equipment. Excess condensate is pumped to a drain fitting on the bottom of the enclosure and can be collected if necessary.

Dri-Gas systems contain a diaphragm sampling pump with brushless DC motor providing operational life in excess of 10,000 hours. The pump is capable of pulling inlet line vacuum of up to 10″ Hg. making it suitable for sampling duct systems with negative pressures. The outlet of the pump is controlled by an adjustable rotameter allowing system sample flow to be set to the normal ate of 500 cc/min. A differential pressure switch across the pump provides an alarm should the inlet line or outlet lines become blocked. An alarm lamp on the door provides local alarm indication and a SPDT alarm contact is available for remote alarm indication.

An optional inlet filter assembly is available for applications where gas streams may contain dust or debris that might cause problems in the air pump. A replaceable filter element on the end of the inlet assembly can be easily changed when necessary.

A plugged inlet filter will be indicated by a fault indication. A package of filter elements are supplied with the inlet assembly.

Features

  • Condensing water vapor removed continuously
  • Sample from ducts under vacuum
  • Gas sensor “blinding” eliminated
  • Virtually maintenance free
  • Options for 120 VAC or 230 VAC operation

Installation

The gas sampling system is suitable for either indoor or outdoor installation, but outdoor installations must be protected from wind driven rain. It is also best to protect it from direct sunlight to minimize solar heating or the interior. Outlet tubing containing the dried air sample should be connected directly to the gas sensor flowcells and distances should be kept as short as possible. Teflon lined PVC sample inlet and outlet tubing is recommended to minimize loss of reactive gases.

The diagram below shows a typical installation with the output to an F12 transmitter. This is an example only. The dried gas sample can be fed to a variety of gas sensors including ATI’s D12, D12IT, B12, F12 or other manufacturers.

E12-15IR High Level Ammonia Gas Detector from ATI
The E12-15IR High Level Ammonia Gas Detector is a rugged reliable microprocessor based intelligent gas detector. The E12-15 can be used to monitor from ppm levels to explosive levels of ammonia gas. The E12-15 is ideally suited for use in harsh environments where electrochemical sensor life can be short. Areas such as engine rooms, emergency vents, or other high level NH3 areas are excellent applications. The E12-15 IR Infrared Gas Detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology. The E12-15 IR is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to full scale. The Model E12-15 IR uses infrared absorption technology for detecting ammonia gas. Gases absorb infrared light only at certain wavelengths. The concentration of a gas can be quantified by measuring and comparing intensities in light bands where there is significant absorption by the target gas. The Model E12-15 IR uses an infrared light source that passes collimated light through a waveguide containing the gas sample. At the other end of the waveguide is a multi channel receiver. The measuring channel intensities and the reference channel intensities are then analyzed to quantify the gas concentration. The gas concentration is then represented at the output as a gas density measurement of % Vol measurement or ppm.

Features

  • Requires no routine calibration to ensure proper operation
  • Continuous self test automatically indicates a fault, with fail to safe operation
  • A multi layered filtering system protects optics from dirt and water ingress
  • Straight optical path eliminates the need for reflective surfaces, such as mirrors or beam splitters
  • Highly resistant to poisoning and etching
  • Standard 4-20 mA output
  • Explosion proof housing designed for harsh environments

Series A24 Puffer Bump Test Gas Generator from ATI

Many safety programs require response testing of the portable detectors used for personal monitoring, prior to use. Fixed detectors must also be tested to ensure they remain sensitive to the target gas.

Regulator “puff tests” can provide a quick check of sensor response. These involve briefly exposing the gas sensors to a puff of air containing a small amount of the target gas. This is often done quite effectively using cylinder gas from calibration cylinders. However, the high cost of the cylinder gas can make this test fairly expensive. What’s more, compressed gas cylinder can be difficult to transport, creating possible supply problems for users.

The A24 Puffer is a portable, battery operated instrument containing a gas generator and simple hand pump that provides the puff of air needed for sensor response checks.

For puff testing diffusion gas detectors, the Puffer includes a short outlet tube. Gas is ejected from the generator by pressing the bladder on the front of the unit. For testing detectors with internal sampling pumps, a plug on the unit is removed so that the sampling pump can pull air through the generator cell for delivery to the detector.

Puffers are water resistant for use in any environment and are designed to intrinsic safety standards. Generator cells provide hundreds of tests, with an LED to indicate the remaining life of the generator cell. Generator cells are easily changed and the life indicator can be reset when a new generator is installed.

Puffer units are available for testing the following gas sensors:

  • Chlorine
  • Hydrogen Sulfide
  • Ammonia

PortaSens III Gas Leak Detector from Analytical Technology
The ATI PortaSens II has been updated to the PortaSens III portable gas leak detector. The new PortaSens III is a rugged hand held device used to detect leaks of toxic or otherwise dangerous gas and also to detect oxygen displacement. The D16 quickly adapts to measure different gases by inserting the appropriate gas sensor module which retains all of the calibration and configuration settings for the target gas. An internal pump with a flexible wand is included for point sampling around suspect pipe fittings and confined spaces. Readings and settings are presented on a backlighted, resistive touch, color graphics LCD with a beeper to notify you of alarms and other events. Readings are recorded in .csv files (ASCII text, comma-separated values) and transferred to a PC using the supplied USB cable. No external application is required. The files may be opened with any text editor or directly by applications like Microsoft Excel. Power is provided from a rechargeable NiMH D-cell battery. The battery should be removed and charged in an external charger after each use. The battery is not used or even required when the device is connected to a USB port. The inlet port, located on the manifold lid, is fitted with a quick disconnect fitting to connect the flexible want. The wand can be used for probing closely around pipes and fittings and for sampled confined spaces without entering. The wand is lined with Teflon and is inert to nearly all vapors and gases. Flexible tubing may be connected to the inlet port to sample high gas concentration or those beyond the reach of the wand. Fluorocarbon based tubing is strongly recommended for measuring low concentrations of reactive gases. Other materials may be used for high range measurements where the adsorption of gas by the tubing is negligible or where you are probing or significant leaks. The internal walls of the wand and any inlet tubing must be kept dry. Water on the walls may absorb soluble gases and decrease the gas readings, presenting an unsafe condition. If the inside of the wand or tubing gets wet, dry dry air through it for 10-15 minutes. Features Interchangeable smart sensors for over 30 gases Internal sample pump and external sampling wand One hand pistol grip design Easy to read back lit color graphics, LCD Instantaneous and timed sampling modes of operation Visual and audible alarms Internal datalogger with RS-232 output Specifications Range Dependent on gas, see chart below Display Backlighted, resistive touch sensitive 320 x 240 color graphics LCD with an anti-glare overlay.

Gas Sample Pump for Fixed Point Systems from Analytical Technology
A21 Sampling Systems use a high quality diaphragm pump operated by a brushless DC motor to provide continuous sampling over long periods of time. Sampling pumps are rated for over 10,000 hours of continuous operation and diaphragms in the pump may be changed easily if necessary. The pump will draw samples against a vacuum of up to 10″ Hg for sampling negative pressure duct systems when necessary. In addition to the sampling pump, A21 systems contain various components needed to insure reliable sample measurement. A flowmeter mounted on the front panel allows the user to adjust the sample flowrate to the desired value, normally around 500 cc/min. Internal to the system is a loss of flow detector that will warn of sampling system problems that could compromise the gas measurement system. A loss of flow alarm light on the front panel provides local flow loss indication while an internal relay can be used to indicate this alarm remotely. Installation Monitoring gas levels using a sample draw system requires that the installation be done carefully and that the nature of the target gas be considered. In general, it is best to locate the gas sensor on the vacuum (inlet) side of the sample system. This insures that the gas sample will be measured before contacting pump or flow detection components that might affect gas concentration. This is especially important when sampling for reactive gases such as chlorine, sulfur dioxide or acid gases. The type of tubing used on the portion of the sampling system between the sample point and the inlet port of the gas sensor is another important consideration. Reactive gases require the use of Teflon or other fluorocarbon tubing, while non-reactive gases can be samples using flexible PVC tubing. Sampling from gas streams saturated with moisture may require heated sample tubing, and the effect of condensation on the gas sensor must be carefully evaluated. For fastest response, gas sampling lines between the sample point and the inlet to the gas sensor should be kept as short as possible. Sample transport time depends on the internal diameter of the sampling tube used as shown below.

The D12-IR utilizes a compact IR sensor in a corrosion resistant housing with sintered flame arrestor to meet hazardous area classification requirements and is suitable for most plant environments. The D12-IR gas transmitter eliminates the poisoning problems inherent in catalytic bead sensors. While catalytic LEL sensors offer reliable service, the presence of silicon vapors, hydrogen sulfide and halogenated hydrocarbons can quickly degrade sensor performance. Infrared sensing technology is not susceptible to these potential interferants which means greater measurement stability and longer sensor life. The D12-IR transmitter can also be configured with Infrared sensor for carbon dioxide (CO2) or nitrous oxide (N20) detection. All sensor versions can operate in diffusion mode for ambient air or with a flow cell for pumped samples. The D12-IR is available in four configurations:  For measurement and data transmission to remote display and alarm equipment, the D12-IR operates in 3 wire mode. Integral LCD indicates gas concentration as well as alarm conditions Transmitter with HART for plants operating with HART protocol communications systems, the D12-IR can be supplied with this option. The HART output supports both 4-20 mA and constant current mode of operation. Transmitter with integral relays for systems requiring local alarm functions or systems where discrete outputs are desired, the D12-IR can provide 3 relay outputs. Relays are assignable to any alarm setpoint or fault condition and are fully programmable for setpoint, hysteresis and time delay. When RS-485 communication is desirable, D12-IR transmitters with alarm relays can be supplied with a Modbus interface. software supports up to 247 unique addresses for large system use. Features  Infrared sensing element is protected inside a stainless steel assembly with a sintered stainless steel flame arrestor. Because the IR sensor is always in an active state, the transmitter continuously monitors critical sensor functions and indicates any sensor problems both on the display and through the analog output. D12-IR transmitters can be factory calibrated for volumetric methane measurements in special applications. Ranges from 0-10%, to 0-100% by volume are available. A separate sensor is also available for high percent level measurements of heavier hydrocarbons such a butane and propane. Each time a sensor is zeroed or spanned the data is stored in memory. Calibration history can be recalled and sensor condition reviewed by operating personnel when necessary. Optional relays outputs can be used for local alarm functions. All relays are programmable for setpoint, hysteresis, on-delay, off-delay and other variables. Even a remote reset feature is provided for in the transmitter design. Transmitter analog output can be set to user definable values. This provides for complete loop testing without the need to apply gas to the sensor Alarm relays may be activated on command to allow testing of local alarm devices. Any combination of relays may be activated based on operator selection. Output and alarms may also be inhibited for maintenance and calibration.  The transmitter is available with either HART or MODBUS protocol. The HART protocol supports the HART Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS protocol supports 9600 baud access to concentration and status information and supports alarm setup and many other functions on either RS485 or RS232 (software selectable). Comes with a register/tag database on a 3 1/2″ diskette. Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. A back light is available.  Measured gas values are stored at user definable intervals and can be recalled when needed on the LCD display. Data can be downloaded using an MODBUS interface. Each time a sensor is zeroed or calibrated, the data is stored in memory. Calibration history can be recalled and sensor condition reviewed by operating personnel whenever necessary. Operating functions such as calibration, alarm setup, alarm reset, data view and setup options are all available using a magnetic tool. It is never necessary to open the enclosure when making adjustments.  Program settings stored in the transmitter may be protected by a user selectable password. Operators may still review all function, but changes may only be made by authorized personnel. Transmitter analog output can be set to user definable values and relay outputs can be set to specific states for complete simulation of detection system operation. Output and alarms may also be inhibited for maintenance and calibration. The D12 electronic assembly plus easily into a terminal board in the base of the enclosure. Transmitters can be easily removed for wiring and quickly replaced in the event of a fault condition. Transmitters are designed for operation in hazardous areas.

Ozone Calibration Gas Generator
The use of ozone gas is increasing rapidly in a wide variety of applications, such as water treatment, odor control and food processing. As the number of ozone generators in use has expanded, the need for gas leak detection near the generators or at ozone application points has expanded. And with expanded use of ozone leak detectors has come the need for a tool to generate the low level ozone gas needed to calibrate ozone sensors. ATI’s Model A23-14 is a portable generator designed to produce an ozone gas concentration below 1 ppm, which can be used for detector calibration at almost any location. The generator uses a compressed air cylinder to supply dry air to an ultraviolet cell where ozone gas is formed. The resulting flow of air with a small amount of ozone exits the generator cell through fluorocarbon outlet tubing that is used to deliver the ozone standard to a gas sensor. Operation of the ozone gas generator is very simple. The UV generator cell is plugged into any convenient power outlet and the valve on the air cylinder is opened. The cylinder valve is a fixed flow regulator so that no flow control is required. The outlet tubing from the generator is connected to your ozone gas sensor for whatever period is needed for calibration and then the system is shut off. Generator output is nominally around 0.8 ppm, but each generator is individually marked with an accurate ozone gas concentration value measured prior to shipment. Ozone generators are supplied in a durable molded case with sufficient space for outlet tubing and calibration adapters. The basic kit contains the generator, one 103 liter air cylinder with fixed flow regulator and 3 feet of outlet tubing. Specifications Generator Type Ultraviolet Output Nominally 0.8 ppm, but individually certified Accuracy ± 0.1 ppm Warm-Up Time 1 minute Air Supply 103 L cylinder with a fixed flow regulator Outlet Flow 500 cc per minute Power 120 VAC, 50/Hz standard Temperature Limit 5 to 40°C Ordering Information For pricing, please call AFC International at 1-800-952-3293, 219-987-6825 or fax 219-987-6826 or email sales@afcintl.com.

Series D12 Digital Gas Detection Transmitter from ATI
Series D12 Digital Gas Transmitter from Analytical Technology features loop powered transmission, loop powered with HART, transmitter with integral relay or a transmitter with MOBUS. Gas detection systems come in all shapes and sizes. Some require simple 4-20 mA transmission. Some are better suited to local alarm relay functions. Some relay require both. And increasingly, digital communication directly to the transmitter is desirable. Not to mention the fact that self-testing sensor capability adds to the reliability of any system. We could not come up with a catchy name that would convey all the capabilities of the D12, so we’ll just explain everything our transmitter can provide – starting with our four different configurations. Features For measurement and data transmission to remote display and alarm equipment, the D12 will operate in 2-wire mode (except for combustible gas). Integral LCD indicates gas concentration as well as alarm conditions. Loop powered with HART for plants operating with HART protocol communications systems, the D12 can be supplied with this option. Our HART output supports both 4-20 mA and constant current mode of operation. Transmitter with integral relays for systems requiring local alarm functions, or systems where discrete outputs are desired, the D12 can provide 3 relay outputs. Relays are assignable to any alarm set point or fault condition and are fully programmable for set point, hysteresis and time delay. When RS-485 communication is desirable, D12 transmitters with alarm relays can be supplied with a MODBUS interface. Software supports up to 247 unique addresses for large system use. Operating functions such as calibration, alarm setup, alarm reset, data view and setup options are all available using a magnetic tools. It is not necessary to open the enclosure when making adjustments. Measured gas values are stored at user definable intervals and can be recalled when needed on the LCD display. Data can be downloaded using MODBUS interface. Gas concentrations are display in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. a backlight is available when operating in 3 wire mode. Program settings stored in the transmitters may be protected by a user selectable 4-digit password. Operators may still review all functions, but changes may only be made by authorized personnel. The D12 electronic assembly plugs easily into the power supply board in the base of the enclosure. Transmitters can be removed for wiring and quickly replaced in the event of a fault condition. Transmitters are designed for operation in hazardous areas. The case aluminum housing for the D12 transmitter is rated for Class 1, Division 1, Group B, C, D locations and is UL, FM and CSA certified. The output range for a particular sensor is programmable within the range boundaries set in that sensor. Optional relay outputs can be used for local alarm functions. All relays are programmable for set point, hysteresis, on-delay, off-delay and other variables. Even a remote reset feature is provided for in the transmitter design. Transmitter analog output can be set to user definable values. This provides for complete loop testing without the need to apply gas to the sensor. Alarm relays may be activated on command to allow testing of local alarm devices. Any combination of relays may be activated based on operator selection. Output and alarms may also be inhibited for maintenance and calibration. The transmitter is available with either HART or MODBUS protocol. The Hart protocol supports the HART Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS protocol supports 9600 baud access to concentration and status information and supports alarm setup and many other functions on either RS-485 or RS-232(software selectable). Sensor Flexibility No matter which style of transmitter you choose, your D12 transmitter includes features that enhance performance and provide operational flexibility, starting with out own advanced electrochemical sensors. Every toxic gas transmitter will accept up to 46 different sensors, greatly reducing the need for multiple transmitter models. The self aligning sensor holder simply plugs in, with automatic sensor recognition and verification when contact is made. Plug-in sensors store calibration data, allowing sensors to be calibrated separately from the transmitter. This allows bench calibration (or factory calibration) of sensors to reduce the necessity for carrying calibration gas around the plant. Sensors are even interchangeable with ATI’s C16 PortaSens II portable gas detector. Each time a sensor is zeroed or calibrated, the data is stored in sensor memory. Calibration history can be recalled and sensor condition reviewed by operating personnel whenever necessary. Sensor Response Verification For many toxic and combustible gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to insure system integrity. Sensor response is verified with an actual gas sample, generated on demand. Electronic sensor and circuit tests just cannot provide the same level of confidence.  Auto-Test gas generators are easily installed and removed when necessary. Generators store run time information accessible to operators and are automatically tested for compatibility with the installed sensor. Systems using the Auto-Test generators store a testing log indicating the number of tests performed as well as test results. This data is stored in individual sensor memory for later review.

A14/11 Economy Modular Gas Detection System from Analytical Technology
GasSens is a flexible component system providing a variety of options to meet individual gas detection and alarm requirements. Economical and low maintenance, this system is your best choice for reliable leak detection. GasSens detection systems consist of individual modules that can be located where required. Sensor/transmitters located in the area where gas leakage or buildup might occur, provide the basic measurement for the system. Sensor transmitters are available in either NEMA 4X or explosion-proof versions and can be supplied with ATI’s exclusive Auto-Test automatic sensor testing system. Receiver modules provide the electronic brains for the detection and alarm system. Each compact module includes a digital display of gas concentration, isolated analog output, and 4 relay outputs. Receivers may be located up to 1,000 feet from sensor/transmitters for remote indication or can provide local control functions such as valve shut off while transmitting a 4-20 mA signal to remote displays or dataloggers. Receiver modules provide an interface between the detection system and external alarming and data logging requirements. One module is used with each sensor/transmitter. Features The LED display Indicates gas concentration directly in ppm, ppb or %. The display may be operated in high intensity mode for outdoor use or in normal mode for indoor application An isolated 4-20 mA output is standard. The output will drive loads up to 1,000 ohms for use in recording, data logging or computer input. Two alarm setpoints are factory adjusted to standard values but may be set to any value from 5% to 100% of range. Front panel LED’s marked Warning and Alarm indicate the status of each alarm setpoint. A standard alarm time delay of 2 seconds or a longer delay of 10 seconds may be selected. In addition, alarms may be switch programmed to activate either above or below the setpoint. Three alarm output relays are SPDT with unpowered contacts for use in activating external signaling devices, control elements or for input to telemetry or annunciator systems. Each relay may be assigned to either alarm setpoint for application flexibility. Relays are factory set to energize on alarm, but may be switch programmed for fail safe operation. Relays may be also set either latching or non-latching operation. Trouble alarm & relay should the sensor/transmitter input be lost, a trouble light (LED) on the front panel will flash and an associated relay will activate. For those systems equipped with the Sensor Auto-Test feature, this alarm will also activate if the sensor does not respond to the automated gas test.  A single front panel switch marked A/R serves a number of functions. When an alarm occurs, the switch will silence an audible horn wired to the module and will change the alarm lights from flash to steady on. After the alarm condition has cleared, the switch will also activate an electronic module test, inhibit alarm contacts and activate the sensor Auto-Test. Terminals are provided for connection of a remote reset switch so that alarms can be acknowledged form a remote location or through a telemetry system. External electrical connections are made to plug in terminal blocks. Should module service ever be needed, modules can be replaced in minutes. GasSens gas detection systems employ electrochemical sensors developed and manufactured by ATI. Expertise in electrochemistry and sensor design provide the foundation for leak detection systems that perform continuously with minimal maintenance. Sensors are rated for ambient temperature from -25 to 50ºC, allowing both indoor and outdoor applications. Excellent zero stability and high sensitivity and selectivity combine to make ATI sensors the best available. Gas sensors are closely coupled to a digital transmitter for excellent noise immunity and the ability to transmit long distances using unshielded cable. The transmitter is powered from the receiver module and uses a unique current pulse position technique to send information to the receiver over a two wire connection. The receiver connection in not polarity sensitive, virtually eliminating the possibility of incorrect transmitter wiring. Sensor/transmitters can be located up to 1,000 feet from receiver modules. Sensor/transmitters are housed in shielded NEMA 4X enclosures for use in almost any industrial environment and are designed to meet intrinsic safety standards. An explosion proof version is available. Auto-Test – Savings & Safety A major expense in gas detection systems is the cost of regular testing to ensure that sensors are responding. This requires a technician to inspect sensors weekly and apply a small amount of gas manually to check response. ATI has developed a unique system to reduce this maintenance requirement. Available on most ATI digital sensor/transmitters is an option called “Auto-Test.” This option consists of an electrochemical gas generator closely coupled to the sensor. Every 24 hours, the receiver automatically activates the generator, producing a small amount of gas that diffuses into the sensor, just as it would if a gas leak occurred. The microcomputer is the receiver analyzes the output of the transmitter to determine that the sensor is responding normally. When proper sensor response is detected, the generator is turned off and the system goes back to normal operation. If no sensor response is detected, the TROUBLE light on the receiver will flash and the trouble relay will activate. During testing, alarm relays are inhibited so that external alarms are not activated. The Auto-Test feature ensures that each sensor is regularly tested with gas. Premature sensor failure or blockage of the sensor membrane is quickly detected. In addition, self-testing will alert maintenance personnel when a sensor has reached the end of its useful life. Since sensors normally last anywhere from 12 months to over 3 years, this feature allows users to determine when sensor replacement is needed. Power Supply Module A compact universal power supply in a DIN rail module similar to the receiver was developed. The power supply will accept any AC or DC input from 85 to 225 volts, without adjustment. Other options include a battery back up system and horn and strobe light options.

Series B12 Gas Detection Transmitter from Analytical Technology
Series B12 gas detection transmitters are loop powered instruments that transmit a 4-20 mA signal linearly proportional to gas concentration. Operated from a 24 VDC power supply, the transmitter will drive loads up to 675 ohms. Alternatively, the unit can operate at 12 VDC – with reduced output load – for applications requiring battery operation. Transmitters are normally supplied with the sensor close coupled to the enclosure. However, for special applications, the unit can be supplied with separate sensors that can be located up to 25 feet from the transmitter. Sensor duct mounting adapters and sensor flowcells can also be provided for specific applications.

Explosion proof optional, Class 1, Div 1, Groups B, C & D Controls Zero and span potentiometers mounted on transmitter circuit board Display Optional 3-digit LCD (not available with explosion proof enclosure) B12 Series 2-Wire Transmitter for Wet Gas Streams Increasingly stringent air quality requirements have led to expanded use of wet scrubber systems to control air emissions. Chlorine storage facilities and chemical process plants are frequently required to scrub exhaust gas streams to remove halogen and acid gases. Unfortunately, monitoring reactive gas concentration in moisture saturated air streams presents problems for standard diffusion sensors. Condensing water in these air lines can quickly blind diffusion sensors, rendering them inoperable. ATI’s Series B12 Wet Gas System was developed to meet the need for reliable measurements in wet scrubber outlets for other gas streams that might be saturated with water vapor. Systems have been developed for monitoring strong oxidants (chlorine, bromine, chlorine dioxide, or ozone), acid gases (HCl or HF) and hydrogen. The basic B12 Wet Gas System consists of a loop-powered 2-wire transmitter and a corrosion resistant sensor specifically engineered to operate at 100% RH. Sensors are designed for direct insertion into vent stacks or may be used in a flowcell if sample can be pumped to the sensor. When remote display and alarm relay functions are required, the B12 Wet Gas Transmitters can be connected to ATI’s B14 Alarm Receiver System. This system will provide direct digital display of gas concentration, plus 3 alarm setpoints, remote alarm reset input and retransmit 4-20 mA output. Or, the B12 transmitter may be used separately and tied directly to the users DCS, PLC or other equipment. Either way, the B12 is an excellent solution to a difficult monitoring problem.

UniSens Universal 2-Wire Transmitter
The UniSens universal 2-wire gas transmitter handles 28 different gases, providing the most economical and flexible gas measurement system available today. Time was, monitoring multiple gases meant using different gas transmitters – each with its own maintenance problems, its own appetite for spare parts, its own installation headaches and so on. Never again, thanks to ATI. The UniSens universal 2-wire gas transmitter handles 28 different gases, providing the most economical and flexible gas measurement system available today. Combining universal electronics, bench calibration capability, automatic sensor verification, fault detection and alarming and superior sensor technology, UniSens is your best transmitter choice. UniSens is designed for ambient gas monitoring in all kinds of industrial environments: gas storage areas, gas compressor rooms, process piping galleries, rail car sidings, analyzer shacks, gas cabinets, chemical process areas and more. In fact, the UniSens transmitter can be used most anywhere that hazardous gas conditions might develop either through leakage or through natural build up. ATI sensing modules consist of an electrochemical gas diffusion sensor and a solid state memory assembly. These sensors provide excellent response time, maximum selectivity and superior temperature stability for reliable gas sensing in a wide range of environments. The companion memory assembly stores operational information and calibration constants, along with gas sensor identification, sensing module range and software revision level. Complete sensing modules are housed in convenient snap-in packages that mate easily with UniSens transmitters. This unique combination of sensor and memory lets you calibrate sensing modules with any UniSens transmitter. So instead of calibrating in the field, you can bench calibrate sensing modules with a spare transmitter; once the sensors are snapped into a field transmitter, their calibration constants upload automatically. The UniSens microcomputer controlled transmitter provides a local digital display and a 4-20 mA analog output proportional to gas concentration. It works with any ATI sensing module, configuring its own display and output range automatically based on data read from the module’s memory. Zero and calibration data is also read into memory, so the transmitter is automatically calibrated when it’s connected to a calibrated module. Magnetic controls on the front of the transmitter allow field calibration, manual activation of the Auto-Test feature (if installed) and review of sensing module data including gas type, range and number of successful Auto-Tests. The transmitter can also act as an analog output simulator to facilitate complete loop testing. Outputs of 4.0, 12.0 and 20.0 mA are selectable via the front panel, along with a trouble signal of 3.6 mA. The transmitter is housed in a durable cast aluminum shell with an 11 pin octal base for easy installation and removal. And since UniSens transmitter are 100% interchangeable, one unit can service as a backup for every type of gas in use.

The Auto-Test gas generator is coupled to the end of the sensor as an integral part of the sensing module. Every 24 hours, the transmitter activates the generator and monitors the sensor for response. If the sensor responds properly, the system reverts to normal operation; if it fails, output is driven to 3.6 mA to signal trouble. (During testing, the output signal is held at the pre-test value). The transmitter maintains a log of completed tests and can display the time until the next scheduled test. An operator can manually activate the Auto-Test, too. Combustible Auto-Test Sensor Now sensor response can be verified every 24 hours automatically. Combustible gas detectors are used in a wide variety of industrial plants to detect gas leakage or buildup before it reaches explosive levels. These detectors rely on thermal oxidation of any combustible gas or vapor on the surface of a heated catalyst. In other words, they simply burn the gas and measure the heat released in the combustion process. While this type of sensor is generally stable and reliable, it is also subject to poisoning by silicon vapor, lead compounds and other environmental contaminants. To detect loss of sensitivity, most users test combustible sensors either weekly or biweekly to ensure response. The procedure is simple, but requires manpower to perform the test. ATI’s Auto-Test Combustible Gas Transmitter eliminates the need for frequent response checks. This transmitter performs an automatic gas test on the sensing element every 24 hours. The result is a combustible gas detector system with a level of reliability beyond that of any other system available. This daily sensor response verification is as close to a fail-safe detection system as you can find, with the added benefit of greatly reduced manual testing. Transmitter Features  Transmitters contain an LCD display indicating LEL values locally. Non-intrusive calibration using a magnetic transmitter controls allow adjustments without removing enclosure cover. Manual Auto-Test -the hydrogen generator may be activated manually on command to observe sensor response, if desired. The result of each Auto-Test is logged in transmitter memory. Operators may review the number of passes and fails from the LCD. The 4-20 mA output from the transmitter may be manually set to 3, 4, 12 or 20 mA in order to test external alarm devices. Electronic transmitters are modular, plugging into a standard relay base for ease of service. Where installations require the sensor be located remote from transmitter electronics, sensor may be supplied with an explosion-proof junction box and a remote gas feed system to facilitate calibration. Auto-Test System Operation Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas, heating the active element and changing its resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration. As long as the active element remains in good condition, the sensor will respond rapidly to the presence of combustible gas. The Auto-Test sensor is actually a combination of a gas sensor and an electrochemical hydrogen gas generator (patent pending) integrated into an explosion-proof stainless steel housing. When activated by the electronic transmitter, the generator produces hydrogen that diffuses to the gas sensor through the flame arrestor protecting the sensor. If the sensor responds properly, the transmitter will show a “Pass” indication. Should the sensor not respond properly, and “Auto-Test Fail” message will activate at the transmitter and the 4-20 mA output from the transmitter will drop to 3 mA, providing for remote fault indication.

Model C12-17 Combustible Gas Transmitter from Analytical Technology
The Model C12-17 is a stand alone gas transmitter designed to detect potentially hazardous concentrations of combustible gases in ambient air. Gases and hydrocarbon vapors such as methane, propane, butane, gasoline, toluene, hydrogen and many others can be reliably monitored in process buildings, analyzer enclosures, pump stations and gas compressor stations. In fact, anywhere gases or vapors may build up to explosive levels can be readily monitored using this transmitter. C12-17 Combustible Gas Transmitters are three wire transmitters, operating from 24 VDC power supplies and transmitting a 4-20 mA signal proportional to 1-100% LEL (Lower Explosive Limit) of a particular gas or vapor. The transmitter is available either as a blind transmitter or with integral LCD display that provides local indication of gas concentration, visible through the glass window in the explosion proof housing. Units supplied with the integral display also contain a single alarm setpoint and relay for local alarm purposes. This integral is a latching alarm that can be reset with a magnetic tool without opening the enclosure. C12-17 transmitter can be connected directly to PLC, DCS or computer based alarm systems without additional hardware. If complete alarm systems are needed, ATI can supply Series B14 modular alarm receivers or Series C14 multi-point scanning alarm units to provide all required alarm functions. Sensor Operation Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas, heating the active element and changing it’s resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration. Explosion proof sensor assemblies are made of 316 stainless steel for maximum corrosion protection. A sinter bonded flame arrestor provides the gas diffusion path to the sensing elements while maintaining the flame proof integrity of the assembly. Sensing elements are specially designed for maximum poison resistance and long life in harsh industrial environments, with sensor life typically 2 years or more.

Dri-Gas Gas Sampling System
Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions. ATI has developed a solution to this problem with a gas sampling system that also conditions the sample by removing water vapor. The Dri-Gas sampling system draws gas samples from high humidity vent stacks, ducts, wet wells or other humid locations. The system removes water vapor from the gas sample by contact with a cold plate that condenses moisture and delivers a dehumidified gas sample suitable for toxic and combustible gas monitoring equipment. Excess condensate is pumped to a drain fitting on the bottom of the enclosure and can be collected if necessary. Dri-Gas systems contain a diaphragm sampling pump with brushless DC motor providing operational life in excess of 10,000 hours. The pump is capable of pulling inlet line vacuum of up to 10″ Hg. making it suitable for sampling duct systems with negative pressures. The outlet of the pump is controlled by an adjustable rotameter allowing system sample flow to be set to the normal ate of 500 cc/min. A differential pressure switch across the pump provides an alarm should the inlet line or outlet lines become blocked. An alarm lamp on the door provides local alarm indication and a SPDT alarm contact is available for remote alarm indication. An optional inlet filter assembly is available for applications where gas streams may contain dust or debris that might cause problems in the air pump. A replaceable filter element on the end of the inlet assembly can be easily changed when necessary. A plugged inlet filter will be indicated by a fault indication. A package of filter elements are supplied with the inlet assembly. Features Condensing water vapor removed continuously Sample from ducts under vacuum Gas sensor “blinding” eliminated Virtually maintenance free Options for 120 VAC or 230 VAC operation Installation The gas sampling system is suitable for either indoor or outdoor installation, but outdoor installations must be protected from wind driven rain. It is also best to protect it from direct sunlight to minimize solar heating or the interior. Outlet tubing containing the dried air sample should be connected directly to the gas sensor flowcells and distances should be kept as short as possible. Teflon lined PVC sample inlet and outlet tubing is recommended to minimize loss of reactive gases. The diagram below shows a typical installation with the output to an F12 transmitter. This is an example only. The dried gas sample can be fed to a variety of gas sensors including ATI’s D12, D12IT, B12, F12 or other manufacturers.

Short Description:

Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions.

E12-15IR High Level Ammonia Gas Detector from ATI
The E12-15IR High Level Ammonia Gas Detector is a rugged reliable microprocessor based intelligent gas detector. The E12-15 can be used to monitor from ppm levels to explosive levels of ammonia gas. The E12-15 is ideally suited for use in harsh environments where electrochemical sensor life can be short. Areas such as engine rooms, emergency vents, or other high level NH3 areas are excellent applications. The E12-15 IR Infrared Gas Detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology. The E12-15 IR is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to full scale. The Model E12-15 IR uses infrared absorption technology for detecting ammonia gas. Gases absorb infrared light only at certain wavelengths. The concentration of a gas can be quantified by measuring and comparing intensities in light bands where there is significant absorption by the target gas. The Model E12-15 IR uses an infrared light source that passes collimated light through a waveguide containing the gas sample. At the other end of the waveguide is a multi channel receiver. The measuring channel intensities and the reference channel intensities are then analyzed to quantify the gas concentration. The gas concentration is then represented at the output as a gas density measurement of % Vol measurement or ppm. Features Requires no routine calibration to ensure proper operation Continuous self test automatically indicates a fault, with fail to safe operation A multi layered filtering system protects optics from dirt and water ingress Straight optical path eliminates the need for reflective surfaces, such as mirrors or beam splitters Highly resistant to poisoning and etching Standard 4-20 mA output Explosion proof housing designed for harsh environments Specifications Detectable Gases Ammonia Range 0-1%, 0-2%, 0-5%, 0-10% & 0-15% Output 4-20 mA (source type) , max 1000 ohm load at 24 VDC supply voltage Response Time T50< 15 seconds T90< 30 seconds Construction 316 stainless steel Accuracy ±3% of full scale for applied gas concentrations up to 50% of full scale ±5% of full scale for applied gas concentrations above 50% of full scale Operating Temperature -40 to 70°C Operating Humidity 0-99% RH non-condensing Operating Voltage 18-32 VDC Power Consumption 5.1 Watts Max Maximum Current Draw Average: 210 mA, Peak 400 mA Approvals CSA: For -40 to 50°C operation, performance tested CAS: C1, Div 1, Groups B, C, D, T5-pending IECEX: C1, Zn 1, Groups IIC, T5-pending Dimensions 5.5x 2.5″ Weight 3.7 pounds Ordering Information For pricing, please call AFC International at 1-800-952-3293, 219-987-6825 or fax 219-987-6826 or email sales@afcintl.com.

Series A24 Puffer Bump Test Gas Generator from ATI
Many safety programs require response testing of the portable detectors used for personal monitoring, prior to use. Fixed detectors must also be tested to ensure they remain sensitive to the target gas. Regulator “puff tests” can provide a quick check of sensor response. These involve briefly exposing the gas sensors to a puff of air containing a small amount of the target gas. This is often done quite effectively using cylinder gas from calibration cylinders. However, the high cost of the cylinder gas can make this test fairly expensive. What’s more, compressed gas cylinder can be difficult to transport, creating possible supply problems for users. The A24 Puffer is a portable, battery operated instrument containing a gas generator and simple hand pump that provides the puff of air needed for sensor response checks. For puff testing diffusion gas detectors, the Puffer includes a short outlet tube. Gas is ejected from the generator by pressing the bladder on the front of the unit. For testing detectors with internal sampling pumps, a plug on the unit is removed so that the sampling pump can pull air through the generator cell for delivery to the detector. Puffers are water resistant for use in any environment and are designed to intrinsic safety standards. Generator cells provide hundreds of tests, with an LED to indicate the remaining life of the generator cell. Generator cells are easily changed and the life indicator can be reset when a new generator is installed. Puffer units are available for testing the following gas sensors: Chlorine Hydrogen Sulfide Ammonia Specifications Power 9 VDC Alkaline battery Generator Electrochemical Generator Life 1000 Cycles for Chlorine, 350 cycles for other gases Pump Manual bladder Display Single digit LED Outlet Tube 6″ polyethylene Enclosure Nema 4X, IP-66 Size 4.7″ x 3.2″ x 2.4″ Weight 0.7 pounds Ordering Information For pricing, please call AFC International at 1-800-952-3293, 219-987-6825 or fax 219-987-6826 or email sales@afcintl.com. Each Puffer bump test generator is supplied with a specific gas generator cell factory installed. Spare generator cells may be ordered separately. Spare generators should be stored in a refrigerator in the sealed container in which they are shipped.
