Abstract
This paper proposes a new method of using the spherical capacitive pro be instead of the common planar probe to increase the accuracy in meas uring the thickness of non-conducting coatings on metals. The measurin g conversion model of the spherical capacitive probe and Its electric circuit are discussed and effective methods for overcoming the unfavou rable influence caused by the spherical capacitive probe are introduce d as well.
