D12 Digital Gas Detection Transmitter from ATI
D12 Digital Gas Detection Transmitter from Analytical Technology features loop powered transmission, loop powered with HART, transmitter with integral relay or a transmitter with MOBUS.
Description
Series D12 Digital Gas Detection 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.
Features
- Backlit LCD Display
- Non-Intrusive operating functions such as calibration, alarm setup, alarm reset, data view, and setup
- Options are all available using a magnetic tool.
- No need to open the enclosure when making adjustments.
- Password Protection
- Modular Electronics
- Scalable 4-20 mA: The output range for a particular sensor is programmable within the range boundaries set in that sensor.
- Three Internal Alarm Relays
- Analog Output Simulation
- Relay Output Simulation
- Serial Communication Interface
Sensor Flexibility
No matter which style of transmitter you choose, your D12 Digital Gas Detection 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.
