Thermal Conductivity CO2 Sensor (CO2 Sensor) MD62 Product Description
-
The MD62 gas sensing element is made based on the principle that the total thermal conductivity of mixed gas changes with the content of the gas to be analyzed. It consists of a detection element and a compensation element paired to form two arms of a bridge. When encountering combustible gas, the resistance of the detection element decreases; when encountering non-combustible gas, the resistance of the detection element increases (air background). The bridge outputs a voltage variable, which increases proportionally with gas concentration. The compensation element provides reference and temperature compensation.
