Abstract: There is described an Eddy current probe for non-destructive testing, comprising: a first leg extending along a first longitudinal axis between a first proximal end and a first distal end; a second leg extending along a second longitudinal axis between a second proximal end and a second distal end; a high magnetic permeability body extending at least partially between the first and second longitudinal axes, the high magnetic permeability body being spaced apart from the first and second legs by a gap and the high magnetic permeability body and the first and second legs being each made of a high magnetic permeability material; and at least one excitation coil each secured to at least one of the first leg and the second leg.

Abstract: A Pulsed Eddy Current device for inspecting an object made of an electrically conductive material comprising: at least one dual-purpose coil serving a dual purpose of producing a supplied magnetic field in the object and measuring a produced magnetic field emitted by the object, a transmitter circuit driving the dual-purpose coil(s) with an electrical signal, a shut-off current circuit for the transmitter circuit for cutting-off a current in the dual-purpose coil(s) during a cut-off phase of the electrical signal, the shut-off current circuit applying a voltage inversion on the dual-purpose coil(s) and a receiver circuit for reading the produced magnetic field from the dual-purpose coil(s). A method for inspecting an object comprising supplying a voltage on at least one dual-purpose coil, cutting-off a current in the dual-purpose coil(s) by applying a voltage inversion on the dual-purpose coil(s) and receiving, at the dual-purpose coil(s), a produced magnetic field.
