UK Alphasense catalytic combustion methane sensor CH4 sensor - CH-D3

1. Catalytic combustion methane sensor CH4 sensorCH-D3Introduction:
Catalytic combustion gas sensorMethane sensorCH-D3 utilizes the thermal effect principle of catalytic combustion. It consists of a detection element and a compensation element paired to form a measuring bridge. When encountering combustible gas, the combustible gas combusts on the surface of the detection element carrier and under the action of the catalyst, raising the carrier temperature, which correspondingly increases the internal platinum wire resistance, thereby unbalancing the balanced bridge and outputting an electrical signal proportional to the combustible gas concentration.
