摘要：To measure the content, in a gaseous medium, of a combustible gas whose nature is known, a resistance-type element either with a catalytic surface or which is sensitive to variations in concentration of said gas in said medium is heated electrically; the value of a quantity representative of the concentration of said gas is detected, and, according to a conversion law established beforehand by calibration, a measurement for said conversion is deduced. Said element is heated in a cyclic manner, in cycles consisting of a heating phase, a second phase during which the intensity (I) is adjusted to maintain the resistive element at a set temperature and the stabilised value of the voltage (U) at the terminals of said detector is measured, and a third phase during which the heating power is reduced. On average, the electric current flowing during the second phase is appreciably lower than the heating current.
