Abstract

Gas detector apparatus, characterized in that it is composed of a balanced wheatstone bridge, in one of whose branches a heating resistance is inserted, this bridge being connected to a source of electrical voltage, capable of producing a heating of the heating resistance to produce the catalytic combustión of the gas put in contact with this resistance, this bridge behaving on the other hand in its diagonal of exit of an apparatus that detects its imbalance.
