UK alphasense catalytic combustion methane sensor CH4 sensor
The catalytic combustion methane sensor CH4 sensor CH-D3 utilizes the principle of thermal effect from catalytic combustion. It consists of a detection element and a compensation element paired to form a measuring bridge. When encountering a combustible gas, the gas combusts on the surface of the detection element's carrier and under the action of the catalyst, causing the carrier temperature to rise, and the internal platinum wire resistance correspondingly increases, thereby unbalancing the balanced bridge and outputting an electrical signal proportional to the concentration of the combustible gas.
