Abstract

Sonde de détection de variations de composition d'un flux de mélange gazeux à partir d'un effet de pile sur une électrolyte solide dont une face est soumise aux gaz à mesurer et l'autre face à un gaz de référence, l'électrolyte solide ayant la forme d'un tube ouvert à ses extrémités et traversé par le gaz de référence passant à l'intérieur du tube-électrolyte, dont surface externe est balayée par le flux de gaz à mesurer. Le tube électrolyte débouche en porte à faux dans la veine d'écoulement, son gaz de référence débitant en circulation dans ladite veine par l'orifice de l'extrémité libre dudit tube. Application au dosage des variations de composition des gaz d'échappement d'un moteur à combustion interne en cours de fonctionnement en vue de sa dépollution.
