  • Patent number: 5138268
    Abstract: A device and method for detecting the thickness of an essentially nonconducting material during movement of the material within the dielectric between the plates of a capacitance detection probe is disclosed. The detection probe is electrically coupled to a material thickness analysis system containing an oscillator with an output frequency that is a related to the dielectric between the plates. Storage and analysis of output frequencies for the oscillator with and without the nonconducting material between the plates generates material thickness information.
