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.
  •  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. The cast 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.

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.

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.

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.

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.

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.

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

RaeGuard 2 PID Fixed Detector for VOCs
The RaeGuard 2 PID is a fixed photoionization detector (PID) that measures a broad range of volatile organic compounds (VOCs). The RaeGuard 2 PID from Honeywell by Rae Systems operates on 10 to 28 VDC and provides an analog (4-20mA) three-wire single output, and RS-485 Modbus digital signal output. Calibration and maintenance have been greatly simplified as the digital PID module can be easily removed in hazardous locations for calibrations and maintenance. The RaeGuard 2 PID has a graphic display and LED light status indicator for fault and alarm conditions. In addition, Low, High and Fault relays can be configured to trigger external alarms or process controls. Over 200 correction factors are pre-programmed and allow users to display readings of a specific target gas. A magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.

Features

  • Class 1, Division 1 (Zone 1) continuous VOC monitoring solution for hazardous locations
  • Three wire 4-20 mA analog output and RS-0485 digital communication in ModBus protocol
  • Three dry contact relays (<30V, 2A) normally open (or normally closed), one for High and Low alarm, another for Fault alarm
  • Explosion proof stainless steel enclosure suitable for outdoor hazardous environment applications
  • Magnetic key interface eliminates the need to open the explosion proof housing when adjusting parameters
  • Continuous VOC monitoring in hazardous and non-hazardous area locations
  • Reduced maintenance costs due to easily removable sensor module. Sensor and lamp can be removed without tools and serviced in hazardous locations
  • Faster response time with sample flow through design powered by internal diaphragm pump
  • Humidity compensation ensures accurate readings even in humid environments

SEC 3100 literature

SEC 3000 Gas Detection Sensor from Sensor Electronics

The SEC 3000 gas detector is a unique design combining intrinsically safe and explosion proof approved standards. This allows for quick and simple field installation of a calibrated sensor module into the gas detector in hazardous locations with power applied. The SEC 3000 sensor module retains operating parameters and calibration settings. Once the sensor module is plugged into the gas detector, the sensor module automatically uploads current information to the control board in the SEC 3000. Changing to a different type of gas sensor is accomplished by only changing the sensor module board. The existing housing and wiring remains intact.

An industry standard 4-20 mA analog output provides remote alarm, fault and calibration signals. The entire unit utilizes self-diagnostics, identifies problems and simultaneously transmits status.

The SEC 3000 can be used in conjunction with the SEC 3100 explosion proof transmitter. The SEC 3100 has a backlit LCD display, non intrusive local calibration, 4-20 mA output, optional relays, RS485 interface and intrinsic barrier.

Features

  • Compact low cost design
  • No field gas calibration required
  • Intrinsically safe and explosion proof
  • Universal control board
  • Interchangeable sensor modules for oxygen and toxic gases
  • Temperature compensated sensor
  • Stand alone gas detector with 4-20 mA output
  • Corrosion resistant 316 stainless steel housing construction
  • Long life electrochemical sensors
  • Can be mated with SEC 3100 transmitter
  • Optional heater with closed loop temperature control ensures accuracy in low temperature applications

Applications

  • Petrochemical
  • Medical
  • Semi conductor
  • Mining
  • Pulp & paper
  • Offshore

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.  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. The cast 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.

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.

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 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.

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.

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.

SEC 3000 Gas Detection Sensor from Sensor Electronics
The SEC 3000 gas detector is a unique design combining intrinsically safe and explosion proof approved standards. This allows for quick and simple field installation of a calibrated sensor module into the gas detector in hazardous locations with power applied. The SEC 3000 sensor module retains operating parameters and calibration settings. Once the sensor module is plugged into the gas detector, the sensor module automatically uploads current information to the control board in the SEC 3000. Changing to a different type of gas sensor is accomplished by only changing the sensor module board. The existing housing and wiring remains intact. An industry standard 4-20 mA analog output provides remote alarm, fault and calibration signals. The entire unit utilizes self-diagnostics, identifies problems and simultaneously transmits status.
