High-Performance High-Temperature Corrosion Detector with Advanced Lift-off Features

Electromagnetic Acoustic Transducer (EMAT), a new technology emerging in the field of non-destructive testing, uses electromagnetic coupling to both generate and detect ultrasonic waves. Compared to conventional ultrasonic testing techniques, EMAT offers advantages such as high precision, no need for couplant, non-contact operation, suitability for high-temperature inspections, and ease in exciting various ultrasonic waveforms. As a result, electromagnetic acoustics is increasingly gaining attention and recognition in industrial applications.

EMAT electromagnetic ultrasonic technology consists of a permanent magnet and a conductor carrying alternating current. As AC energy flows through the non-contact coil, it generates an alternating magnetic field, which induces eddy currents on the surface of the base material. Charged particles moving within this magnetic field experience the Lorentz force, causing them to repeatedly change direction along the surface of the object being inspected. This Lorentz force induces controlled micro-vibrations in the particles within the eddy current region, ultimately generating ultrasonic waves at the surface of the base material. The rebounded ultrasonic energy is then directly detected by the non-contact coil—primarily through mechanisms like magnetostriction—and the resulting detection signals provide valuable characteristic data.
