Patent ID: 7768258

Claim:
An apparatus for monitoring the position of a conductive target, said apparatus comprising: a. an eddy current probe, wherein said eddy current probe comprises an inductor which can be positioned near said conductive target; b. an oscillator connected to said inductor, said oscillator being capable of generating a frequency to excite said inductor; c. a cable electrically connecting said oscillator to said probe, said cable and said probe forming a resonant circuit having a particular probe identification and a resonant frequency; d. a demodulator connected to said eddy current probe, said demodulator capable of receiving an input from the eddy current probe and generating an output; e. an analog to digital converter connected to said demodulator, said analog to digital converter capable of receiving the output from the demodulator; and f. a table unique to the particular probe identification utilized in the apparatus, said table generated based on the resonant frequency of a probe and cable configuration having the particular probe identification.
