The DSC01-G50K-SG catalytic combustion gas sensor operates based on the principle of catalytic combustion. It consists of a sensing element and a compensating element paired as one arm of a bridge. When combustible gases are encountered, the resistance of the sensing element increases, resulting in a change in the bridge output voltage. This voltage change is directly proportional to the gas concentration, with the compensating element serving as a reference and providing temperature and humidity compensation.
Features
* High stability
* Excellent resistance to poisoning
* Fast response and recovery time
* Not affected by orientation
* High linearity
Applications
