ABSTRACT:
A method and apparatus for determining thickness of a metallic layer being deposited on a collector. The method includes applying an electromagnetic field to a conductive layer on the collector. Then the temperature or the change in temperature of the collector is determined. The metal thickness is determined as a function of the temperature or change in temperature. The apparatus includes a collector, a thermocouple associated with the collector, and a source of an electromagnetic field.
