Abstract

Device for detecting and dosing at least one constituent of a gas mixture by catalytic reaction, which carries two elements of identical and variable electrical resistance as a function of temperature, placed in the zone of said gas mixture and the surface of one of which is they are subjected to a catalytic reaction that affects their temperature in the presence of the gaseous constituent to be dosed, their variation of electrical resistance resulting from that of the other element being the analogical electrical measurement of said gaseous constituent, characterized in that the resistant elements they are strong metal wires of the same metal, one of which is coated with a catalyst layer.
