Abstract:
In a method for calibrating at least one sensor having at least one signal-conducting connection to at least one signal converter, a sensor characteristic is recorded by the determination of at least one measurand at at least two different temperatures, the extent of the influence of a further value influencing the sensor is determined from the sensor characteristic by means of a functional relation, the extent of the influence of the further influencing value is considered in the calibration and the influence of the further influencing value is balanced in the calibration. As a result, the influence of a further influencing value acting on the sensor is corrected. The sensor can be a structure borne sound sensor which may have a membrane with a sensor element arranged on the membrane. Vibrations on the membrane can be captured by the sensor element, such as a piezoresistive element.
