Catalytic Combustion Gas Sensor
Application:
Concentration detection of hydrogen, acetylene gasoline and organic vapour such as alcohol, ketone and benzene in the industrial fieldProduct characteristics:
Good stability1. Description
ZC2521-A catalytic combustion type gas sensor works according to the principle of catalytic combustion effect, by the detection element and compensation element pairing constitute a bridge arm, in the combustible gas detection element resistance increases, the bridge output voltage changes, the voltage variable increases with the increase of gas concentration and proportional to the compensation element reference and temperature and humidity compensation.
