Abstract

a. Dispositif de mesure de la pression partielle d'oxygène utilisant une pile à concentration d'oxygene en électrolyte solide conduisant les ions oxygène pour déterminer la pression partielle d'oxygène de gaz d'echappement. b. Il comprend une structure monolithique et un élément cylindrique dans lequel sont placées et auquel sont fixées ladite pile à concentration d'oxygène et ladite structure monolithique, de façon à ce que le gaz d'échappement que l'on doit étudier atteigne ladite pile à concentration d'oxygène après qu'il ait traversé ladite structure monolithique. c. Mesure du taux d'oxygène dans les gaz d'échappement.
