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