The complicated type nondestructive inspection apparatus using the hybrid magnetic induction thin film sensor

摘要

The present invention relates to a hybrid nondestructive inspection apparatus using a hybrid induction magnetic thin film sensor , and more particularly is , applying an alternating magnetic field in the excitation coil by using a permanent magnet and at the same time induces a magnetic flux induced in the subject by the magnetization of the test body is wound with a leakage flux change of the magnetic flux induced in the subject on the sensor core within the thin film sensor by detecting part that the nose , to be able to quantitatively check the size of the defect as well as the test body including specialized operation and can detect the defect by a simple operation without the need for , surface , the back surface of the subject in a single measurement , the internal and can detect all the defects of the outer , or a material non-magnetic or magnetic body of the subject is possible for both the effect regardless of particle . ;
