Gas sensors based on tin dioxide for exhaust gas application, modeling of response for pure gases and for mixtures

Résumé

This paper concerns tin dioxide gas sensors for automotive exhaust gas application. It consists in elaborating robust sensors on alumina substrate by screen-printing technology. Sensors have been tested on a synthetic gas bench which is able to generate high gas velocity and gases at high temperatures close to real exhaust gas conditions. The responses of the sensors to three gases were modeled, and the classical model of electrical conductivity with one reducing or oxidizing pollutant gas was extended to mixtures. Comparisons between models and experiments are presented with good agreements.
