  • Diagnostic device for detecting short circuits or line interruptions in an inductive sensor
    Patent number: 6456085
    Abstract: A symmetrical voltage divider whose tap is supplied with a reference voltage via a resistor is connected between the terminals of an inductive sensor. A diagnostic voltage is applied to the tap. Using evaluation devices, the diagnostic voltage is compared with two threshold values in a stationary state, and then sampled in the operational state, and a difference is calculated from the largest and smallest sampled, values and is compared with a third threshold value. Short circuits or line interruptions are detected from the comparison result and are displayed.
