1. Description

The ZC25B-1 catalytic combustion gas sensor works according to the principle of catalytic combustion effect. It is composed of a detection element and a compensation element paired to form an arm of the bridge. When encountering combustible gas, the resistance of the detection element increases, and the output voltage of the bridge changes. The voltage change increases in direct proportion to the increase in gas concentration. The compensation element plays a role in reference and temperature and humidity compensation.
