The leakage magnetic field detection technology mainly uses magnetic sensors such as Hall devices to detect changes in the leakage magnetic field by partially magnetizing the test piece.
Linked by the driver and the recorder, the transverse excitation MFL inline detector is mainly composed of a support system, a drive system, a magnetization system, a sensor system.
As a common non-destructive testing method, steel pipe magnetic flux leakage testing has formed a complete set of industry standards and specifications.
