1. catalytic combustion gas sensor CH-A3 product introduction:
The catalytic combustion gas sensor uses the thermal effect principle of catalytic combustion. The detection element and the compensation element pair to form a measuring bridge. When encountering combustible gas, the combustible gas burns under the action of the detection element carrier surface and the catalyst. The temperature of the carrier increases, and the resistance of the platinum wire inside it also increases accordingly, so that the balance bridge loses balance and outputs an electrical signal proportional to the concentration of combustible gas.
