The sensing element is made of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater.
In the presence of the gas to detect, sensor conductivity increases according to the gas concentration in the air.
A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
Gas sensor with high sensitivity to low concentrations of air contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke.
The sensor can detect hydrogen at a level of several ppm and is housed in a standard TO-5 case.
Due to the miniaturized sensing chip, the heater requires a current of only 42mA.
The range is 1-30ppm of hydrogen.
