Abstract

L'invention concerne un détecteur d'oxygène et de NO¿x? combiné. D'une manière générale, le détecteur combiné met en oeuvre un corps de détecteur (220) comprenant deux types différents d'électrodes des couches d'électrodes poreuses à l'oxygène (16a, 16c) et des couches d'électrodes poreuses à l'oxygène et dissociatives (16b, 16d). Selon un mode de réalisation de l'invention, le détecteur comprend un corps de détecteur, une sortie de signal électrique de teneur en oxygène et une sortie de signal électrique de teneur en NO¿x?. Le corps du détecteur est disposé dans le gaz et comprend une pluralité de couches d'électrodes poreuses à l'oxygène et une pluralité de couches d'électrodes poreuses à l'oxygène et dissociatives. Les couches d'électrodes poreuses à l'oxygène et dissociatives comprennent un matériau sélectionné pour la dissociation de NO¿x? en azote et oxygène.
