Abstract
A method is disclosed for operating a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, with a characteristic of the sensor arrangement being recorded in an initialization phase from measured values of the at least one measuring sensor and of the at least one reference sensor, and an alarm being given during continuous operation if the deviation from the characteristic lies outside a tolerance band. It is proposed to suspend the alarm dynamically so long as the changes in the measured value in the variation over time of the at least one measuring sensor or in the variation over time of the at least one reference sensor differ by more than a definable limit within a definable time interval.
