ABSTRACT:
In a process for determining the percentage of combustible gases in air by means of a detection element catalytically supporting the combustion, this detection element is heated with an excitation function according to a predeterminable current-voltage pattern, and the response function resulting from this is investigated with respect to the position of its maximum (differentiation). If a time interval limit (3) is exceeded by the maximum, a first gas type factor is sent to the evaluating circuit, and if the maximum does not reach the interval limit (3), a second gas type factor is determined and is evaluated as a calibrating value and for the classification of the combustible gases to be investigated.
