Abstract:
1. A proximity sensor interface device (PSID) for determining if a proximity sensor is in an acceptable position with respect to a target device, said PSID comprising: a frequency generator; a processing device; a memory associated with said processing device, wherein said memory comprises a sensor response envelope stored therein comprising: a display; an RC circuit, said processing device programmed to route a signal generated by said frequency generator through the proximity sensor and said RC circuit for a prescribed period of time, said processing device programmed to measure a discharge time of said RC circuit, said processing device programmed to determine whether a response of the proximity sensor satisfies a threshold associated with the high response curve and the low response curve, said processing device further programmed to cause said display to provide an indication of whether a relative position of the proximity sensor and target device are within prescribed tolerances, based on the discharge time; and an enclosure housing said frequency generator, said processing device, said memory, and said RC circuit, said enclosure including a handle and configured for hand-held use.
