Product Description:

The MD heat conduction gas sensor is made according to the principle that the total thermal conductivity of the mixed gas changes with the content of the gas to be analyzed. The detection element and the compensation element are paired to form an arm of the bridge. The resistance of the detection element becomes smaller when it encounters a gas with a larger thermal conductivity than air, and when it encounters a gas with a smaller thermal conductivity than air (air background), the output voltage of the bridge changes, and the voltage variable increases with the gas concentration. It increases proportionally, and the compensation element plays a role of reference and temperature compensation.
