Catalytic Combustion Gas Sensor

ZC28/ZC28C Catalytic Combustion Type Gas Sensor

for industry gas monitoring

Application:

Concentration detection of flammable gases such as natural gas,liquefied gas, coal gas,and alkanes at industrial sites,flammable gas leak alarms, flammable gas detectors, and gas concentration meters

Product characteristics:

Good stability
Quick response
The bridge output is linear
Good repeatability and selectivity
Excellent resistance to the interference of H2S gas and organosilicone

1. Description


    The ZC28/ZC28C 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 variable increases in direct proportion to the increase of gas concentration. The compensation element plays a role of reference and temperature and humidity compensation.
