Abstract

Senseur d'oxygène destiné à déterminer la teneur en oxygène des gaz d'échappement d'un moteur à combustion interne. Senseur comprenant une résistance au bioxyde de titane et une résistance au bioxyde de zirconium montées dans un isolateur en céramique disposé dans un boîtier métallique adapté à être connecté au système d'échappement du moteur; la valeur de la seconde résistance ne varie qu'en fonction de la température des gaz tandis que la valeur de la première résistance varie en fonction à la fois de la température des gaz et de leur teneur en oxygène, de sorte que l'effet de la température des gaz sur le senseur se trouve réduit ou éliminé pour sa plage de fonctionnement. Senseur d'oxygène applicable aux moteurs d'automobiles.
