Abstract
An eddy current probe which can be moved by hand to a surface to be tested. A toroidal-shaped first resilient member contacts the bottom face of a support member. An elastic membrane extends over the bore of the first resilient member, contacts the bottom lateral surface of the first resilient member, and is unattached to the radially-inward-facing surface of the first resilient member. A more elastic, second resilient member is placed in the bore, is unattached to the first resilient member, and contacts the bottom surface of the elastic membrane. A flexible, surface-conformable, eddy current sensing coil overlies a portion of the bottom side of the second resilient member.
