ABSTRACT:
An analytical circuit for an inductive electromagnetic sensor with external excitation (1) generates an output signal which is transformed to give an output signal (out), by means of transformation to a reference voltage (Vref) in an inverting low-pass filter (12), which has no hysteresis delay and is free from multiple triggering. By comparison of the reference voltage with three voltage thresholds in a diagnostic circuit (6), line interruptions and short-circuits are recognised by battery voltage or reference voltage potentials.
