Abstract
The invention relates to an active sensor element for recording the speed of an exhaust gas turbocharger, comprising a suppressor circuit which has at least one diode. In order to specify a device for temperature measurement at the turbocharger and in particular at the turbocharger in the region of the active sensor, the current-voltage characteristics of the diode are evaluated for determining the temperature in the sensor element.
