Abstract
In order to monitor the correct mounting of a rotation transducer on a rotary part, the output signal of the rotation of the indicator is caused to produce a first pulse at a particular angular position. An additional reference mark transducer is coupled to the rotary part to produce a second pulse for timing comparisons with the first pulse. Mechanical slippage of the rotation transducer on the rotary part can then be detected when one of the pulses is present without the other, and the failure of either of the transducers to operate can also be detected. The device is useful for assuring reliable operation of the rotation transducer controlling fuel injection in a Diesel engine.
