Abstract

Procédé de mesure et/ou de calibrage d'un détecteur de gaz (10) servant à déterminer en particulier les composants gazeux contenant de l'oxygène dans des mélanges gazeux, notamment dans les gaz d'échappement de moteurs à combustion interne, * le détecteur de gaz ayant au moins une électrode intérieure (21, 31), au moins une électrode extérieure (22) et au moins une électrode de décomposition (41) pour décomposer de manière électrochimique certains composants gazeux, * au moins une électrode intérieure (21, 31) et au moins une électrode de décomposition (41) étant installées dans des chambres ou segments (20, 30, 40) du détecteur de gaz qui sont séparées, et * un courant ionique induit par la décomposition des composants gazeux déterminés est utilisé pour déterminer les composants gazeux, procédé caractérisé en ce que la mesure et/ou le calibrage est effectuée pendant le fonctionnement courant du détecteur de gaz (10) en ce que, - dans une étape (a), par une opération de pompage électrochimique, on enlève le composant gazeux à déterminer et/ou l'oxygène d'au moins l'une des chambres ou segments (20, 30, 40), - dans ne étape (b), par des opérations de pompage électrochimique, on introduit de manière ciblée de l'oxygène dans au moins l'une des chambres ou segments de chambre (20, 30, 40), - on mesure les variations produites par l'oxygène introduit par rapport à une autre électrode (51), et - en utilisant les valeurs mesurées on mesure et/ou on calibre le détecteur de gaz (10).
