  • Operating method and sensor for gas analysis
    Patent number: 4703646
    Abstract: A method for using a dynamic gas sensor for analysis and detection of one or more gases or gas components of a gas mixture includes using the response time constant for the gas sensor to the gas as a measured value so that detection ensues from the response time constant. Selectively different behavior and sensitivities of the gas sensor occurs by selection of its operating temperature, or by varying the temperature, or by modulation of its temperature at predetermined frequencies. A sensor for use in the present method may include a heating element integrated therewith and may also include a plurality of detectors arranged in an array.
