Abstract :
This paper presents a moving magnetic flux type sensor with shading coils for eddy current testing. We have developed a new sensor which uses the moving magnetic field generated by shading coils to detect cracks and defects on the reverse side surface of an object. In this paper, the development and improvement of our new NDT sensor are shown by means of FEM and some results are discussed
