EMAT Transducer
EMAT Transducer
An EMAT (Electromagnetic Acoustic Transducer) is a non-contact inspection device that gives an ultrasonic pulse in the unit or example examined, instead of the transducer. An EMAT Transducer makes ultrasonic waves into a test aim with 2 interacting magnetic areas. Electromagnetic-acoustic transducers acts by completely various physical principles and do not require couplant. EMAT transducers make ultrasound waves in electric conductive materials through Lorentz force, through electro magnetostrictive impact, or through a mixing thereof.
