Abstract

L'invention concerne une cellule de mesure permettant de déterminer la concentration en oxygène d'un mélange gazeux et comprenant dans un corps de cellule isolé intérieurement deux électrodes, une de référence au contact de l'air et l'autre de mesure au contact du gaz à analyser, cette cellule étant pourvue d'une paroi de séparation en oxyde de zirconium stabilisé. Cette paroi de séparation est constituée par une plaque dont la surface concave des bords latéraux vient s'imbriquer de façon étanche dans un épaulement de surface complémentaire convexe prévu dans un support métallique transversalement solidaire du corps de cellule. Application aux moteurs à combustion interne.
