Product Introduction
SME- 005 catalytic combustion gas sensor works on the principle of catalytic contact combustion effect. It is composed of a detection element and a compensation element paired to form an arm of the bridge. When encountering combustible gas, the resistance of the detection element increases, and the output voltage of the bridge changes. The voltage variable increases in direct proportion to the increase in gas concentration. The compensation element plays a reference and temperature and humidity compensation role
