DEVELOPMENT OF A SOFTWARE-ALGORITHMIC METHOD FOR PROCESSING THE THERMOCATALYTIC SENSORS CHARACTERISTICS FOR THE IDENTIFICATION OF FLAMMABLE GASES IN AIR AND MULTICOMPONENT MIXTURES

Software-algorithmic method for processing the temperature characteristics of a catalytic sensor for recognizing the type and determining the concentration of flammable gases in multicomponent mixtures has been developed and its applicability has been evaluated. The scheme of the software-algorithmic method is presented, experimental studies of single-component, two-component and multicomponent mixtures consisting of hydrocarbons and hydrogen are carried out. The results showed that the method makes it possible to recognize the type of combustible gas and determine the concentration with an accuracy of up to 90%.
