Measuring non-conducting thickness on conductors - using eddy current coil with frequency varied to adjust phase

A measuring method for the thickness of non-conducting coatings on electrically conducting and magnetic materials is for producing measurement results independent of the coated material characteristics or tilting of the measurement probe. The eddy current principle is employed in which a coil carryi...
