It is a general-purpose DC MPI equipment dedicated for working pieces with AC/DC MPI requirement (military, aeronautics, astronautics, manufacturing and maintenance and repair enterprises). DC inspection is able to detect deeper flaws due to small skin effect and even distribution on internal surface of inspected working pieces; AC inspection has strong skin effect, and it is complementary to DC inspection and increases the function of the equipment.

Features and Functions:

AC/DC magnetization, full-wave or half-wave DC with a certain detection depth;

AC inspection is equipped with cut down phase control applying method of continuation and residual field method for flaw detection;

Resultant magnetization, AC automatic attenuation and AC super-low frequency demagnetization;

Electrical, pneumatic or manually pedaling;

Controllable silicon adjusting, continuous adjustable current, overvoltage and over temperature protection;

TRMS of AC;

3P full-wave DC magnetization is equipped with prompt interruption function to enable end face detection;

Automatic tracking of magnetization current and automatic compensation.
