Abstract

Sonde de dosage d'un composant de flux gazeux par mesure de sa pression partielle à partir d'un élément de mesure dont la résistance varie en fonction de cette pression partielle à la La variation de résistance de l'élément de mesure propre à la température est compensée par comparaison avec la résistance d'un second élément soumis à la variation de température et insensible à la pression partielle du composant à mesurer. Application à la mesure de la pression partielle d'oxygène dans le flux de gaz d'échappement de moteurs à combustion interne.
