Abstract
Procédé de contrôle d'un capteur thermocatalytique pour les systèmes de télémesure de la concentration de méthane dans les mines, dans lesquels un capteur comportant un élément thermocatalytique sensible dans une chambre de réaction qui est limitée par une paroi perméable aux gaz est introduit d'une façon fixe dans le système de la mine, caractérisé en ce que lors du branchement du capteur en régime de fonctionnement de mesure et lors de l'application d'une tension électrique à son élément sensible pour l'obtention d'une température de chauffage requise, on détermine le signal maximal de sortie du capteur directement au moment de son branchement et ensuite on mesure le signal de sortie stabilisé du capteur et la durée du processus transitoire entre lesdits signaux maximal et stable.
