ABSTRACT:
An apparatus for detecting a disconnection of a sensor by monitoring a signal in a signal-carrying line for receiving an output signal of the sensor through a connector. The apparatus includes a feeder circuit for causing a current to flow through the connector to the sensor for a predetermined time period in the absence of the output signal of the sensor. The current flow causes elimination of an oxide film produced in the connector with time, resulting in the prevention of attenuation of the output signal due to the oxide film and in ensuring accurate detection of the disconnection of the sensor irrespective of secular change.
