Electromagnetic acoustic transducer

EMAT (or electromagnetic acoustic transducer) is a device that receives and transmits ultrasonic waves in conductive or magnetic materials. This inspection method offers many advantages including non-contact and complaint-free operation, ability to measure coated materials and the ability to excite special wave types that provide advantages in certain test applications. The non-contact EMAT approach provides significant advantages in time, cost, quality and appearance of tested pipe.
