Magnetic resonance tester

01. Thread Inspection

By applying eddy current and ultrasonic methods, fine defects on the surface and inside of the rolling roll are found
It is a system that can measure stress.

In particular, the Array-type eddy current sensor is a fatal disadvantage of the conventional rotary eddy current sensor
By eliminating the phenomenon of the insensitivity zone caused by the lift-off phenomenon, the defect detection capability
It has a dramatically improved and has a semi-permanent lifespan with no mechanical drive elements.
