MC115 Catalytic Element Product Description
-
The MC115 catalytic element operates 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 combustible gases, the resistance of the detection element increases, causing a change in the bridge output voltage. This voltage change increases proportionally with gas concentration, while the compensation element provides reference and temperature/humidity compensation.
