Monicon CGS500 Thermocatalytic Combustible Gas Sensor

Combustible gas sensorThe Monicon CGS500 combustible gas sensor has been designed to measure concentrations of combustible gases in the range 0-100% LEL. The CGS500 is fitted in an EExe certified junction box.

Each sensor contains two thermocatalytic beads. Combustible gases oxidise on the surface of the active bead whilst the reference bead compensates for changes in temperature, pressure etc. Each bead consists of a coil of fine platinum wire surrounded by an alumina based substrate containing a catalyst.

An electric current is passed through the bead which raises the temperature to a level where oxidation will occur. The catalyst reduces the temperature at which oxidation occurs, thus prolonging the life of the bead and resulting in much lower power consumption. 


Key Features:

  • Detects most hydrocarbons
  • Fast response time
  • Low drift
  • Not affected by catalytic poisons
  • Temperature compensated
  • Wheatstone Bridge (pellistor) compatible
  • Sensor MTBF of 10 years
  • Rugged stainless steel body
  • Many accessories options
  • Certified ATEX II 2 G EEx d IIC T6
