Abstract

On the basis of a transformer-type eddy current transducer, a measuring system has been constructed that allows one to estimate the possibility of using the eddy current method for measuring the thickness of conductive and dielectric coatings deposited on a conductive substrate. The design of the measuring system and the measurement techniques are described. Data that demonstrate the dependence of the amplitude part of the signal on objects of various thicknesses are presented; the maximum object dimensions at which these measurements are feasible have been found experimentally.
