Abstract

Measurements using eddy current transducers in a wide frequency range are considered. Resonance properties have been investigated, hodographs of transducer signals have been constructed depending on the signal frequency and the thickness of the electrically conductive coating on an electrically conductive nonmagnetic base, and the phase method of detuning from the gap for different signal frequencies is considered. A comparative analysis of the dependencies of the amplitude of the insertion voltage and the penetration depth of the electromagnetic field into the coating material at different excitation frequencies of the transducer is performed.
