Catalytic combustion sensor MC105 product description
-
The MC105 catalytic element operates based on the principle of catalytic combustion effect. It consists of a detection element and a compensation element paired to form two arms of a bridge. When exposed to combustible gas, the resistance of the detection element increases, causing a change in the bridge output voltage. This voltage change increases proportionally with gas concentration. The compensation element serves as a reference and provides temperature and humidity compensation.
