Catalytic Combustion Gas Sensor
Application:
Can be used in the lakege alarm or concentration detection of natural gas ,liquefied gas ,coal gas and other combustible gases in civil and commercial fields.Product characteristics:
good stability1. Description
ZC25D 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.
