Abstract

The article presents the structure of a subminiaturized eddy-current transducer (EST) of a transformer type with the exciting, measuring and compensation windings, which is based on the pyramid-shaped core providing the localization of the magnetic field on the area of 0.0025 mmý. It also presents the main transducer parameters that allow providing this localization of the magnetic field. A measurement procedure that allows one to perform high-accuracy monitoring of flaws in different alloys is described. The eddy-current transducer was successfully tested on several objects, e.g., a 5.5 m thick duralumin alloy and welded seams of 5 mm thick titanium plates. The penetration depth of the field of eddy currents into the investigated object is determined and the dependences, describing the response of the ECT at different depths of the defect, are outlined. The dependences of the ECT signal on the flaws in these structures are given
