Abstract

A sensor device comprises a sensor connected to a first signal and responsive to an external field to produce a sensor signal, a test device connected to a second signal and electrically connected in series with the sensor by an electrical test connection providing a test signal, and a monitor circuit electrically connected to the first, second and test signals. The monitor circuit comprises a processing circuit and a determination circuit. The processing circuit is responsive to the test signal and a predetermined processing value to form a processing output signal. The determination circuit is responsive to the processing output signal to determine a diagnostic signal. A sensor circuit responsive to the sensor signal provides a sensor device signal responsive to the external field.
