Catalytic sensor
The MC112 type 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 Wheatstone bridge. When encountering flammable gas, the resistance of the detection element increases, causing a change in the bridge output voltage. This voltage variation increases proportionally with the gas concentration. The compensation element serves as a reference and provides temperature and humidity compensation.
