Title (EN) A DUAL GAS SENSOR STRUCTURE AND MEASUREMENT METHOD
(FR) STRUCTURE À DOUBLE CAPTEUR DE GAZ ET PROCÉDÉ DE MESURE
Abstract:
(EN) The invention relates to a sensor structure and a method. The sensor structure includes a first sensor (1) having a sensing element (13) sensitive to humidity of the environment. In accordance with the invention the sensor structure also includes a second sensor (2) having a sensing element (13) sensitive to humidity, the second sensor (2) comprising a catalytic permeable layer (16) positioned on the second sensor (2) such that it is between the sensing element (13) of the second sensor (2) and the environment.
(FR) L'invention concerne une structure à capteurs et un procédé. La structure à capteur comprend un premier capteur (1) ayant un élément capteur (13) sensible à l'humidité de l'environnement. Selon le mode de réalisation de l'invention, la structure à capteurs comprend également un second capteur (2) ayant un élément capteur (13) sensible à l'humidité, le second capteur (2) comprenant une couche perméable catalytique (16) positionnée sur le second capteur (2) de sorte qu'il est placé entre l'élément capteur (13) du second capteur (2) et l'environnement.
