Magnetic Flux Leakage Testing (MLFT) System

Magnetic Flux Leakage Testing System

Advantages of Flux leakage testing :

  • Highly sensitive test method for the detection of longitudinal defects on steel bars

  • No coupling liquid

  • Quick to install and easy to operate

  • Reliable and reproducible test results

  • Automatic marking and sorting of the tested bars

  • High production speeds

  • Several reporting options

AC flux leakage principle

RFL - Probe Arm

Magnetic Flux Leakage Testing (MFLT)

  • Based on automated Flux leakage inspection system.

  • Uses high energy A.C. Magnetic Leak fields for detection of longitudinal flaws.

  • Real time display of ongoing inspection.

  • Fully automated defective marking & sorting of the material.
