WE WILL FIND A SOLUTION FOR YOUR INSPECTION PROBLEM.

Electro Magnetic Acoustic Transducer (EMAT)

Key Benefits of EMAT

  • No couplant needed.
  • Contact-free to inspection surface. Scanning is possible.
  • Inspection surface should be free from loose deposits.
  • Low spread of shear / transverse waves. High resolution.
  • Operating temperature from -30°C to +550°C.
  • Applicable for almost all metals.
  • Limitations: Casting-Centrifugal casting – cast Alloy 800.
  • Low maintenance cost, easy handling.
