MT Crack Detectors / Sources

Lightweight Testing Benches

Lightweight testing benches MAS series for MT are designed for inspection single pieces up to the batch inspection of ferromagnetic parts for the presence of longitudinally or transversely oriented cracks on the outer surface by means of magnetic particle inspection method.

Standard delivery for all models

  • coil 250 mm (I.D.), manual feed
  • right tailstock with position locking, manual feed, manual lever clamping of inspected part
  • reversible parking position of the coil allowing the insertion of objects from the top
  • stainless steel bathtub with sloped spout in the middle of the tub
  • prismatic supports and clamping Cu plate with contacts made of Cu fabric (replaceable)
  • Fe models have reinforced support structure and clamping tailstock for higher load of tested samples

Recommended sources

Power sources for MAS series magnetizing benches may be used individually, depending on the requirements. Generally, for MAS Al we recommend the source up to ZP 2000 and for MAS Fe – up to ZP 5000. I order to speed up the test cycle, the ideal choice are dual sources, which enable both magnetization by passage of current and coil magnetization simultaneously.

Optional accessories (for extra charge)

  • max. coil dimension of 350 mm (square shaped 400 mm)
  • stationary or hand UV lamps
  • pneumatic clamping with possible cycle automation
  • pump – manual or automatic applying of detecting suspension, circulating system for the testing liquid distribution, stainless steel reservoir with continuous mixing 15, 20 litres (inner shape of the reservoir prevents sedimentation)
  • switch for longitudinal/transverse magnetization after clamping
  • girder for suspension lights
  • darkening cabin
  • tailored clamping panels
  • adjustable nozzles system for serial testing
  • secured both-hands operation
  • short supporting legs


Modifications are possible according to the customer's requirements and wishes.
