SensAlert IR Infrared Gas Detector 

The fixed point Non-Dispersive Infrared (NDIR) LEL detector is designed for performance in harsh and hazardous Hydrocarbon gas environments. Utilizing solid-state infrared technology, this detector delivers dependable hydrocarbon gas detection with minimal maintenance requirements.

• High Reliability and Durability
  The SensAlert IR has a straight-forward design and rugged 316 stainless steel sensor construction to withstand the most demanding applications.

• No Routine Calibration and Virtually Maintenance Free
  There is no scheduled calibration programs required for the operation of this instrument and required maintenance is limited to zeroing. You can practically “fire it and forget it,” except for normal periodic testing.

• Operates in Anaerobic Atmospheres and Constant Hydrocarbon Background
  The self-contained optics fully function in applications where there is no oxygen or hydrocarbons are regularly present. The SensAlert IR optics are also immune to poisoning and etching.

• Dual Wavelength NDIR Technology
  The sensing and reference elements are self-compensating for optical integrity
  and other signal inhibitors.

• 3-Wire 4-20 mA Linear Output
  Detectors can be installed in new construction or retrofits using using 3-wires.  Detectors communicate faults and special functions using signals below 4 mA.

• Dual Infrared Sensors and Remote Mount Capability
  One or two infrared sensors can be mounted locally or remotely up to 250 feet / 76 meters away from the transmitter.
