Title (EN) SENSOR FOR DETECTING NON-BURNT HYDROCARBONS
(FR) CAPTEUR SERVANT A DETECTER LES HYDROCARBURES NON BRULES
Abstract:
(EN) Sensor for the detection of unburnt hydrocarbons, and including a catalytic surface at which a chemical reaction may take place in the presence of the catalyst, where the reaction influences a semiconductor device that in this way can deliver a signal, at which the sensor for the elimination of other disturbing sources to which the sensor is sensitive are detected by means of one or several additional essentially similar sensors where however the actual sensor function has been blocked so that these additional sensors or parts deliver signals corresponding to possible disturbances.
(FR) Capteur permettant de détecter les hydrocarbures non brûlés, qui comprend une surface catalytique sur laquelle une réaction chimique peut se produire en présence d'un catalyseur. La réaction influe sur un dispositif à semi-conducteur qui peut ainsi délivrer un signal. Des sources de perturbation auxquelles le capteur est sensible et qu'il faut éliminer sont détectées au moyen d'un ou plusieurs capteurs essentiellement similaires, mais dans lesquels la véritable fonction de capteur a été bloquée, de façon que ces capteurs ou des parties de ces capteurs délivrent des signaux correspondant aux perturbations éventuelles.
