Ethanol transmitter MT-ETHA


The principle of the change of heat conduction through the adsorption of gas on the surface of metal oxide semiconductor by ethanol sensor determines the concentration of gas by the change of resistance value of platinum coil.
The two arms of the bridge are matched by the detection element and the compensation element.
The resistance of the detection element decreases and the output voltage of the bridge is changed when the alcohol is encountered.
The change of the voltage increases proportionally with the increase of the gas concentration, and the compensation element acts as reference and temperature compensation.
