Abstract (en)
[origin: DE10232941A1] A sensor protection circuit for at least one sensor (6), especially within a motor vehicle power supply network, with at least one power supply cable (3, 4) and at least one current measurement unit (8) for measurement of the current through the supply cable. The current measurement unit is connected to a current limiter or a switch to limit or switch-off the current and thus prevent damage to the sensor by a too-high voltage.
