TEST APPARATUS FOR DETECTING DEFECT OF PIPE USING REOMTE FIELD EDDY CURRENT

摘要

The present invention relates to a test device to detect a defect of a pipe by using a remote field eddy current. According to the present invention, the test device to detect a defect of a pipe by using a remote field eddy current includes: an exciter part stored in a pipe, and forming a magnetic field by receiving a current; a receiver part separated from the exciter part in a longitudinal direction of the pipe, and detecting the magnetic field; a shaft equipped with the exciter part and the receiver part; and a support part installed on the shaft, and attached to the inner wall of the pipe. Therefore, the present invention is capable of having the excellent reliability of measurement by preventing the eccentricity of the exciter part and attaching the receiver part to the pipe.
