Catalytic Combustion Gas Sensor
for industry gas monitoring
Application:
Concentration detection of natural gas, liquefied gas, coal gas, alkane class and other combustible gases in the industrial siteProduct characteristics:
Good stability1. Description
ZC28 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.
2. Application
It can be used to test the concentration of natural gas in domestic and industrial sites. It can also be applied to combustible gas leakage alarm, combustible gas detector, gas concentration meter.
