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.
Leakage magnetic field detection refers to the formation of a leakage magnetic field on the surface or near surface of a ferromagnetic material due to defects after magnetization.
Magnetic Flux Leakage Testing does not require preprocessing of the test object, is easy to obtain detection signals, has a high degree of automation, and can detect different types of defects.
