Probe, rotors, reference blocks



They are used to: detection small  and deep surface cracks of unknown orientation, detection of corrosion on bonded or riveted aluminum layers, wall thickness inspection, penetration of multi-layer aluminum structures, crack detection on complex forged parts, inspection possible very close to the edge of the test specimen, determine differences in the conductivity, inspection of edge turbine blades e.g. Alphajet engine Larzac.

They are used to: dynamic inspection of the inner surface of bore holes, dynamic inspection of the surface holes cone-shaped,  inspection of the holes cone-shaped before and after machining. To

inspect smooth surfaces of bore holes, the probes are manufactured in plastics housing and with a higher sensitivity. They can be connected to rotors SR1, SR2, MR# and SMR4 in version MF- and HF-.

Reference patterns should be used in any application. They are available in many configurations. Reference patterns are manufactured of the following materials:

  • Aluminum
  • Steel
  • Austenitic steel
  • Titanium

 Types and markings:

TP1 – Universaly pattern 4-ply (aluminum, steel, austenitic steel, titanium) with cuts about depth from 0,2 mm to 0,5mm on the each plate. Additional hole is formed Φ 9,5 mm with longitudinal incisions about depth 0,5 mm spaced at 900.
