Abstract

Remote field eddy current was an effective non-destructive testing technology for tubular structure such as pipes and tubes. Firstly, experiment results using conventional sensor, the reason of poor sensitivity was analyzed and discussed by finite element simulation. Secondly, novel high resolution sensor with orthogonal magnetic field and self-differential mode pick-up coil was proposed. At last, proposed senor was verified experimentally using various type defects, and conclusions were drawn as followed: detection ability and sensitivity of remote field eddy current testing system using proposed senor improved significantly compared with using conventional sensor, especially for axial crack which is not easily to detect using conventional sensor, and sensitivity to various types defects remained almost the same.
