Arbejdsprincip for magnetisk flux lækagedetektor
Apr 20, 2025
The working principle of magnetic flux leakage detector is based on the fact that after the ferromagnetic material is magnetized, a leakage magnetic field is formed on its surface due to defects on the surface or near the surface of the test piece. When the ferromagnetic material is magnetized, if there are defects on its surface or near the surface, the magnetic permeability will change, causing the magnetic flux to be Forvrænget, og en del af den magnetiske flux lækker ind i rummet på overfladen af materialet og danner et lækage magnetfelt .
