FIGARO PRODUCT INFORMATION TGS 2201 - for detection of Gasoline and Diesel Exhaust Gas Features: * Dual sensor element * High sensitivity to exhaust gases emitted by both gasoline and diesel-fueled engines * Long life and low cost * Uses simple electrical circuit Applications: * Automobile ventilation control The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater.
In the presence of a detectable gas, the sensor's conductivity changes depending on the gas concentration in the air.
A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the ...
