Honeywell Sensepoint Catalytic Gas Detectors

Honeywell Sensepoint flammable, toxic and Oxygen gas detectors offer users a high quality, low cost solution to their industrial gas monitoring needs. Installation in potentially explosive atmospheres is made by the use of a suitable Ex d or Ex e approved junction box.  (Consider the Honeywell XNX Transmitter  alternately Fluidic can supply with a low cost Bartec JB). The industry standard outputs from Sensepoint are connected to either a choice of Honeywell Analytics’ controllers (such as the Honeywell Touchpoint Plus) or 3rd party DCS/ PLC systems. Honeywell Sensepoint flammable and toxic gas detectors are certified to the latest ATEX/IECEx safety and performance standards.


Honeywell Sensepoint Catalytic Gas Detector Measurement types

  • Flammable 0-100% LEL
  • Flammable PPM (Typically 0-10% LEL)
  • Hydrogen Sulphide (H2S) 20/50/100ppm
  • Carbon Monoxide (CO) 100/200/500ppm
  • Ammonia (NH3) 50/1000ppm
  • Chlorine (Cl2) 5/15ppm
  • Oxygen (O2) 25% V / V
  • Hydrogen (H2) 1000/10,000ppm
  • Sulfur Dioxide (SO2) 15/50ppm
  • Nitric Oxide (NO) 100ppm
  • Nitrogen Dioxide (NO2) 10ppm


Note that for light density gases, such as methane (natural gas) – where the sensor should be mounted at height – consider using the collector cone and gassing block (see photos top left)


Honeywell Sensepoint Catalytic Gas Detector Specs and Benefits

  • PPS Construction, IP65 as standard, IP67 with weather protection fitted
  • ATEX/IECEx Safety Approvals
  • Flammable, toxic and Oxygen versions available
  • High performance, low cost design
  • Suitable for new and retro fit applications
  • SurecellTM electrochemical sensors
  • Poison resistant catalytic bead
  • Fast and reliable
  • Typical 2 to 5 years operational life


The flammable detector is available in either % LEL or PPM detection range versions and provides an industry standard mV bridge output. Typical life expectancy is greater than 5 years, after which the detector is simply replaced with a new one. The toxic detectors are supplied pre calibrated for easy installation and provide an industry standard 2 wire 4-20mA loop output. User connections are Ex d, while front end Intrinsic Safety (IS) design allows for easy exchange of the replaceable sensor while powered. IS design also removes the need for a sinter enabling very fast speed of response and detection of ‘sticky’ gases such as Chlorine and Ammonia.  Honeywell Sensepoint has proven its suitability across a wide range of demanding applications by delivering high performance and reliability at an affordable cost.
