Catalytic Combustion Gas Sensor
Application:
Can be used for leak alarm or concentration detection of natural gas, liquefied gas, coal gas and other flammable gases in (non-industrial) public placesProduct characteristics:
The bridge output voltage is linear and has a fast response speedDescription
ZC25A catalytic combustion gas sensor works according to the principle of catalytic combustion effect. It is composed of a detection element and a compensation element paired to form an arm of the bridge. When encountering combustible gas, the resistance of the detection element increases, and the output voltage of the bridge changes. The voltage change increases in direct proportion to the increase in gas concentration. The compensation element plays a reference and temperature and humidity compensation role.
