Abstract
A combustible gas sensor for detecting a combustible analyte includes a first sensing element including a first conductive element in electrical connection with an electronic circuitry, a first support structure in operative connection with the first conductive element, a catalyst supported on the first support structure for catalyzing a reaction of the analyte, and a system for measuring a variable related to the reactance of the first sensing element. Changes in the measured variable over time provide an indication of an operational status of the first sensing element.
