Catalytic Combustion Gas Sensor
Application:
Concentration detection of hydrogen, acetylene, gasoline, alcohol, ketone, benzene and other organic vapors at industrial sitesProduct characteristics:
The bridge output voltage is linearDescription
The ZC2528-I catalytic combustion gas sensor operates based on the principle of catalytic combustion. It consists of a pair of sensing elements and compensating elements forming one arm of a bridge. When exposed to combustible gas, the sensing element's resistance increases, causing the bridge's output voltage to change. This voltage increases in direct proportion to gas concentration. The compensating element acts as a reference and provides temperature and humidity compensation.
