1. A manufacturing quality control system for monitoring the proximity of a workpiece to a machine tool, comprising:

  • a proximity sensor attached to the machine tool for deriving a first distance measurement based upon the distance between the workpiece and the machine tool;

    a wireless transmitter for generating a radio frequency signal including a first sequence of data representative of the first distance measurement, the wireless transmitter being provided with the first distance measurement from the proximity sensor; and

    a remote data processing device in communication with the wireless transmitter and including a sensor status module for generating proximity information from the value of the first distance measurement as represented by the first sequence of data derived from the received radio frequency signal.
