ZC2521-I Catalytic Combustion Gas Sensor

Application:

Concentration detection of hydrogen, acetylene gasoline and organic vapour such as alcohol, ketone and benzene in the industrial field

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

ZC2521-I 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.
