Standard flaws for eddy current probe characterization
NDT International, 1989 Calibration procedures for eddy current inspections often involve the use of artifact standards containing manufactured flaws. The manufactured flaw is assumed to be a good approximation of the type of flaw being sought during the inspection. These manufactured flaws are most often produced by electrical discharge machining (EDM), milling, or the ...

Eddy Current Probe Performance Characterization
NDT International, 1989 Single-coil, absolute eddy current probes are used extensively by the Air Force for inspection of aluminum airframe structures. Because of the large variations in probe performance [1], a specification is needed to ensure that probes meet minimum performance criteria.

, 1993 Eddy current probes fabricated with cores made of ferrite-loaded silicone rubber RTV are flexible; they can be used to scan components with contours of varying radii. A typical application would be the inspection of rocket nozzles; the radius of curvature changes between the throat and the base, with additional curvature in the axial direction.

Comparison of defect detection limits in Lorentz force eddy current testing and classical eddy current testing [PDF]
Journal of Sensors and Sensor Systems, 2018 Lorentz force eddy current testing (LET) is a motion-induced eddy current testing method in the framework of nondestructive testing. In this study, we address the question of how this method is classified in comparison with a commercial eddy current ...
