ABSTRACT:
A method for testing gauges includes applying a rotation signal to the gauge. An AC input signal is superimposed on a first coil of the gauge. A second coil of the gauge is monitored to detect a coupled AC output signal. The rotational signal is varied while the AC output signal is monitored. The operational status of the gauge is determined responsive to the AC output signal and a process output signal indicative of the operational status is provided.
