Method and device for analyzing a sensor element

Abstract

A method and a device for analyzing a sensor element are described, which allow a temperature dependence of the sensor element to be considered without an additional temperature sensor in particular. The sensor element outputs a signal as a function of a measured variable. The signal of the sensor element is analyzed in a first analysis operating mode to detect the measured variable. The signal of the sensor element is analyzed in a second analysis operating mode to detect a characteristic variable of the sensor element which is different from the measured variable.
