Sensidyne Gas Detection

Point Hydrocarbons - IR

Point Infrared Gas Detector for Hydrocarbon Gas Detection

Point Hydrocarbons - IR
  • High Reliability and Durability

    The Point Hydrocarbon – IR has a straight-forward design and rugged 316 stainless steel construction to withstand the most demanding applications.

  • Dual Wavelength NDIR Technology

    The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors.

  • 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 Point Hydrocarbon – IR optics are also immune to poisoning and etching.

  • No Routine Calibration and Virtually Maintenance Free

    There is no scheduled calibration programs required for the operation of this instrument and maintenance is limited to an annual zeroing.

  • 3-Wire 4-20 mA Linear Output

    These point detectors can be installed in new construction or retrofit situations using using 3-wires. The detectors communicate faults and special functions using signals below 4 mA.

Point Hydrocarbon — Infrared

Using a solid state collimated Infrared light source and self compensating heated optics, the Point Hydrocarbon NDIR LEL detector is ideally suited for use in very harsh and hazardous environments demanding low-maintenance gas detectors. The 316ss explosion proof housing has no mirrors or beam splitters and the optics are sealed from dirt and water ingress. With a 100 mm plus optical path, response time is <5 seconds.

The Point Hydrocarbon Infrared gas detector performs reliably in the presence of silicone and other catalytic poisoning agents and operates in Oxygen-free environments or background LEL levels. There are no known poisons that affect the sensor technology. The advanced processor-based electronics are sealed and have no user access or adjustments. The recommended maintenance interval is one year.
