Electro-Magnetic Acoustic Transducer

EMAT (Electro Magnetic Acoustic Transducers) inspection technique can be used on carbon steel as well as exotic alloys such as 9 Cr, 5 Cr and 304L. Due to the use of magnetism to induce sound into a test piece the EMAT pitch-catch ultrasound can maintain acoustic contact with the rough surfaces, inspect a narrow area, and can scan faster than that of conventional pitch-catch ultrasound.


EMAT can be utilized both for online and offline applications. The diversity of EMAT allows it to be used in a multitude of differing conditions. The high speed screening allows EMAT to cover large areas at a time thus being more time efficient. EMAT tools and system are lightweight, portable and can inspect areas with rough surfaces or coated areas without the use of an additional couplant. EMAT provides 100% coverage and the ease of repeatability for localized and general corrosion is what sets this technology in its own category.
