Fixed combustible, toxic & asphyxiating gas detector - SENSEPOINT
The SensePoint gas detector is an economical and efficient solution that meets the needs of users who want to detect and monitor combustible gas, toxic gas and oxygen in potentially explosive atmospheres (ATEX zones).
This fixed monitor consists of an Exd or Exe approved housing and a certified gas sensor. With an IP65 protection rating, The Honeywell SensePoint fixed gas detector is protected against water and dust infiltration and its four-way connection box makes it very easy to install. Detailed description
The SensePoint fixed gas detector
Flammable gas detector
The Honeywell SensePoint fixed gas detector has a poison resistant pellistor catalytic detection system, which is part of a 3-wire mV bridge measurement circuit. The flammable combustible fixed gas detector measures target gas concentrations between 0 and 100% of the LEL (Lower Explosive Limit) for which it is calibrated.
Fixed toxic gas detector
Equipped with a high performance electrochemical gas sensor, the Honeywell fixed gas monitor detects toxic gases (in ppm) present in ambient air. The SensePoint toxic gas version is available for Cl2, CO, H2, H2S, NH3, NO, NO2 or SO2 gases with a 4-20 mA 2-wire linear output.
Oxygen gas detector (lack of oxygen)
This version of the SensePoint gas detector measures the oxygen depletion as a volume percentage (% / vol.) Like the toxic gas version, it has a 4-20 mA 2-wire linear output.
