EMAT TECHNOLOGY

emat The main specialization of ULTRAKRAFT is a design and production of automated ultrasonic systems using electromagnetic-acoustic transducer (EMAT).

PRINCIPLES OF EMAT

Electromagnetic-acoustic method of the generation of ultrasound  is a method for converting of a high-frequency electromagnetic wave of conductor with current into elastic deformations (ultrasound) on the surface of testing object with the frequency multiple or equal  to electromagnetic wave.

Electromagnetic-acoustic receiving of ultrasound is based on the inverse effect of converting relative to the EMAT-emitting of ultrasound.

EMAT-technology of emitting and receiving of ultrasound have some advantages, which are impossible for others technologies including Piezo-method. They are following:

  • providing of safe and reliable testing of objects with dirty surface;

  • testing of moving objects at high speed without any limitations;

  • testing of objects with extremal curvature;

  • testing of objects at cold and extremal cold conditions without any limitations;

  • testing of heated objects (up to 1200 Celsius degree)
