The present invention relates to a device for measuring the concentration of hydrogen in a gaseous mixture and in particular in the air constituting, for example, the atmosphere inside closed premises. This device comprises a sensor (1) in contact with said gaseous mixture, said sensor (1) being linked to calculating and display means (2), in which said sensor comprises a catalyst (13) capable of provoking an exothermic reaction with the hydrogen contained in the gaseous mixture, conducting means (14) fixed to said catalyst for transferring essentially by conduction the thermal energy released by said reaction from said catalyst (13) to a cold point (18), means for measuring the temperature T1 (21) of said catalyst and the temperature T2 (22) of said cold point (18) being linked to means for calculating the value of the molar concentration of hydrogen in a gaseous mixture from the temperature gradient measured T1-T2, said means of calculation communicating said value of hydrogen concentration to said display means.
L'invention est relative à un dispositif de mesure de la concentration en hydrogène dans un mélange gazeux en particulier dans l'air constituant par exemple l'atmosphère d'un local fermé. Ce dispositif comprend un capteur (1) en contact avec ledit mélange gazeux, ledit capteur (1) étant relié à des moyens de calcul et d'affichage (2), dans lequel ledit capteur comprend un catalyseur (13) susceptible de provoquer une réaction exothermique avec l'hydrogène contenu dans le mélange gazeux, des moyens conducteurs (14) fixés audit catalyseur pour transférer essentiellement par conduction l'énergie thermique générée par ladite réaction depuis ledit catalyseur (13) jusqu'à un point froid (18), des moyens de mesure de la température T1 (21) dudit catalyseur et de la température T2 (22) dudit point froid (18) reliés aux moyens de calcul de la valeur de la concentration molaire en hydrogène dans le mélange gazeux à partir du gradient de température mesuré T1-T2, lesdits moyens de calcul fournissant ladite valeur de la concentration en hydrogène auxdits moyens d'affichage.
