PointWatch™ (PIR9400) IR Gas Detector

ATEXCSAEACIECEx

The PIR9400 is well suited for use in harsh environments and where the cost of required maintenance for conventional catalytic detectors is prohibitive.

The PointWatch™ IR 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's ability to detect hazards.

Features

  • Requires no routine calibration 
  • The internal heating system reduces condensation, allowing reliable operation through temperature extremes
  • Continuous self-test automatically indicates a fault or fouled optics condition
  • Provides a 4-20 mA output signal, corresponding to the detected gas concentration

Technical Specifications

  • Globally certified for use in Class I, Divisions 1 and 2, and Zones 1 and 2 hazardous areas
  • Approved to provide continuous monitoring of methane gas concentrations in the range of 0 to 100% LFL
  • Most flammable hydrocarbon vapors (such as ethane, ethylene, propane, butane and propylene) are also detectable but, the detector has not been third-party approved with them
  • Compliant with the ANSI/ISA 12.13.01-2000 performance standard
