Abstract. The article discusses the results of studying a signal from an eddy-current transducer in the form of an overhead inductive coil. An assessment of the change in the signal from sheets and mats of thermally expanded graphite of various thicknesses and densities is carried out. It was found that the amplitude of the signal resistance depends on the density and thickness of the test object. An uneven distribution of the amplitude over the area of samples from mats and thin sheets was found.
