Abstract

Détecteur d'oxygène à électrolyte solide possédant un revêtement protecteur destiné à protéger le film conducteur de catalyse externe de ce détecteur. Détecteur dont le revêtement est formé du produit de réaction inorganique d'un oxyde et d'un acide inorganique qui forme une matrice destinée à lier les particules discrètes d'oxyde à la manière d'un revêtement adhésif déposé sur le film conducteur. Détecteur applicable à la détermination de la teneur en oxygène des gaz d'échappement des moteurs d'automobiles.
