A new gage system was made based on the eddy-current transducer. The system makes it possible to evaluate the possibility of using the eddy current method to measure the thickness of conductive and dielectric coatings applied on a conductive base material. One of the important advantages of the developed gage system is the possibility of local measurement of the thicknesses of conductive and non-conductive coatings. In this article, in particular, the measurement features are described in detail, as well as the specificity of the gage system. Also it represents data, showing the dependence of signal amplitude on objects of different thicknesses, and experiments proved the limiting dimensions, at which measuring data are useful.
