EMAT Transducers

EMATs (electromagnetic acoustic transducers) are single element transducers that use a magnetostrictive effect to transmit and receive ultrasonic waves. EMATs offer unique advantages—they can be used without couplant, there’s no need to remove external scale prior to an inspection, they can be used in contact or at a small distance from the surface, they can be used on hot parts, and they work well on small-diameter pipes.
