When safety, accuracy, and longevity are non-negotiable, the ATI D12-IR Infrared Toxic Gas Transmitter delivers unmatched performance for gas detection in hazardous environments. Engineered with infrared (IR) sensing technology, the D12-IR is ideal for detecting combustible gases (methane, ethane, propane, butane), carbon dioxide (CO₂), volumetric methane, and nitrous oxide (N₂O). Whether for petrochemical, wastewater, or manufacturing facilities, the D12-IR offers powerful gas detection with minimal maintenance.
Why Choose the D12-IR?
Traditional catalytic sensors can suffer from degradation when exposed to silicon vapors, hydrogen sulfide, or halogenated hydrocarbons. The D12-IR overcomes these limitations by using advanced infrared technology, which is not susceptible to these common sensor poisons. The result is longer sensor life, improved reliability, and consistent measurement stability.
Key Features at a Glance
High-Visibility Display
- LCD Graphics Display with backlight ensures gas concentrations, alarm indicators, and system menus are easy to read even in low-light environments.
Internal Data Logging
- Built-in data logger stores gas concentration values at configurable intervals. Retrieve data on the LCD or download it via the MODBUS interface for detailed analysis.
Non-Intrusive, Magnetic Interface
- All configuration and calibration functions can be performed without opening the enclosure—just use the magnetic tool to access settings via the 3-button interface.
Password Protection
- Safeguard critical settings with a customizable 4-digit password. Operators can still review functions, but only authorized users can make changes.
Modular Electronics
- Easy plug-and-play electronics allow for quick replacement and servicing of the transmitter without re-wiring or extensive downtime.
Robust Design for Hazardous Locations
- Explosion-Proof Enclosure: Cast aluminum housing is UL, FM, and CSA certified for Class 1, Division 1, Groups B, C, D environments.
- IR Sensor with Flame Arrestor: The sensing element is housed in stainless steel with a sintered flame arrestor, meeting rigorous safety requirements.
Advanced Functionality
- Fail-Safe Operation: The IR sensor is always active, continuously monitoring its own integrity and alerting users to any performance issues.
- Scalable 4-20 mA Output: Easily programmable output range based on sensor specifications.
- High-Range Gas Detection: Factory-calibrated options available for methane detection up to 100% by volume, with additional sensors for heavier hydrocarbons.
- Sensor Calibration History: Every calibration (zero/span) is logged for traceability and diagnostics.
- Alarm Relays: Optional three internal relays, programmable for setpoints, delays, and hysteresis, including remote reset functionality.
- Output Simulations: Simulate analog and relay outputs for testing without applying gas.
Communication Options
- MODBUS (RS485 or RS232): Access real-time data, alarm settings, and diagnostic functions at 9600 baud.
- HART Protocol: Supports HART Universal and Common Practice Commands via 1200 baud FSK modem for remote interface and diagnostics.
Application Flexibility
The D12-IR is perfect for:
- Petrochemical facilities
- Refineries
