ABSTRACT:
The invention relates to a sensor protection circuit for at least one sensor (6), especially in a motor vehicle electric system, comprising at least one supply line (3, 4) for supplying current to the sensor (6) and a current measuring unit (8) for detecting the electric current flowing through the supply line (3), in order to prevent damage to the sensor (6) as a result of excess voltage. Said current measuring unit (8) is connected to a current limiting device or to a switch element in order to limit the current or to disconnect the supply line (3).
