Abstract: A centering assembly for an eddy current probe includes a foot element having a plurality of resilient cantilevered legs projecting radially about a central aperture and an adjustment element moveable relative to the foot element for exerting a radial force on the plurality of resilient cantilevered legs. Movement of the adjustment element allows an outside diameter of the plurality of resilient cantilevered legs to be maintained consistent as the plurality of resilient cantilevered legs are worn down during use.

Abstract: A device and method of eddy current based nondestructive testing of tubular structures made of electrically conductive materials is disclosed. The device includes a plurality of excitation electromagnets having an axis of symmetry and magnetoresistive sensors having an easy axis for magnetic field sensing; wherein the magnetoresistive sensors are arranged in a circular array on a single plane with the easy axis aligned radially with respect to the circular pattern and wherein the electromagnets are arranged in a circular pattern on both sides of the plane with their axes of symmetry being arranged parallel to the plane and orthogonal to radii of the circular pattern on which the electromagnets are placed.
