Electromagnetic Acoustic Testing (EMAT) stands at the forefront of non-destructive ultrasonic testing technology, offering a revolutionary alternative to conventional piezo crystal probes. Unlike traditional probes, EMAT operates as a non-contact device, eliminating the need for couplant gel and enabling the generation of ultrasonic waves without physical contact with the test surface.

The EMAT transducer comprises essential components such as an induction coil, magnetic flux concentrator, and permanent magnet, which work in tandem to induce eddy currents on the surface of the test object. These currents, interacting with the permanent magnetic field, generate ultrasonic waves directly on the surface, allowing for precise thickness measurement. Notably, EMAT is unique in its ability to transmit and receive transversal (shear) waves, enabling superior resolution and sensitivity compared to longitudinal waves produced by traditional probes.

TechCorr leverages EMAT technology to offer advanced tank testing systems capable of examining even the largest tanks in the industry, providing a comprehensive approach to tank compliance and integrity management. With the ability to operate with minimal surface preparation and without couplant gel, EMAT represents a game-changing solution for engineers and plant operations managers seeking efficient and accurate non-destructive testing methods.
