Description
вихревые токи. В месте размещени отрезка металлической леиты формируетс локальное неоднородное магнитное поле.

Ориентаци отрезка металлической ленты в пределах от 30 до 60° относительно оси вращени приводит к тому, что локальное неоднородное поле взаимодействует с полем дефекта сначала преимущественно под одной катушкой, затем под другой , что обуславливает по вление сигнала раз-баланса, по которому -суд т о наличии прот женной трещины.eddy currents. A local non-uniform magnetic field is formed at the location of the metal leita section. If there are no cracks in the controlled cylinder, when the modulator 2 rotates around the product, there is no imbalance signal at the output of the differentially connected measuring coils. The orientation of the metal strip in the range from 30 to 60 ° relative to the axis of rotation causes the local non-uniform field to interact with the field of the defect, primarily primarily under one coil and then under the other, which causes the appearance of a time-balance signal. about the presence of an extended crack.
