Abstract
A gas detection device and a process monitor an area for a combustible target gas. A heating segment of a detector () is heated when electrical current flows therethrough. A heating segment of a compensator () is heated when electrical current flows therethrough. An electrical voltage is applied to both the detector and the compensator. The heating of the detector () causes a combustible target gas to be oxidized in an interior of the gas detection device. A detection variable, which depends on the temperature (Temp_) of the detector, and a detection variable, which depends on the temperature (Temp_) of the compensator, are measured. A presence and/or a concentration of a target gas are determined as a function of the detection variables. A quality parameter is measured and increases as the detection variable depending on the detector temperature increases and as the detection variable depending on the compensator temperature decreases.
