Abstract
An electronic monitoring system provides an actual value sensor which detects an actual value of a component to be monitored, e.g., the rotational speed of a drive motor, and emits actual value signals, a signal path along which actual value signals are transmitted, and an evaluating unit connected to the signal path. The signal path is divided into two separate but parallel signal paths along which the actual value signals emitted by the actual value sensor are processed differently. For example, the actual value signals emitted by the actual value sensor may undergo digital signal processing along one path and analog signal processing along the other path. The actual value signals transmitted along the two paths are received by the evaluating unit which compares the signals and initiates appropriate steps if there are deviations between the two sets of actual value signals.
