Abstract
A proximity sensor interface device (PSID) for determining if a proximity sensor is in an acceptable position with respect to a target device is described. The PSID includes a frequency generator, a processing device, a memory associated with the processing device, a display, and an RC circuit. The processing device is programmed to route a signal generated by the frequency generator through the proximity sensor and the RC circuit for a prescribed period of time and the processing device is programmed to measure a discharge time of the RC circuit. The processing device is further programmed to cause the display to provide an indication of whether the relative position of the proximity sensor and the target device are within prescribed tolerances, based on the discharge time.
