The eddy current method is based on electromagnetic induction and is ideal for detecting surface discontinuities and property variations in conductive materials, without the need for direct contact or the use of a couplant.
Eddy Currents (EC)
Inspection of coatings, detection of cracks in conductive surfaces, measurement of layer thickness, inspection of aircraft and heat exchangers.
Fast, portable method, sensitive to surface defects, does not require special preparation of the part and allows the detection of subtle variations in the material.
