A draft of an extended general classification of eddy current designs was proposed. In particular, multielement eddy current transducers, which realize the technology of electronic or combined scanning of the surface of the object of control, as well as the far-field eddy current transducers were added to the proposed classification for the first time. Examples of the design of eddy current transducer structures are given, in particular, of multielement eddy current transducers and far-field eddy current transducers. 26 References, 7 Figures.
