TOFD Transducers & Wedges

Time-of-flight diffraction (TOFD) transducers and wedges generate refracted longitudinal waves in steel and are commonly used to size cracks. The transducers are highly damped, offering excellent resolution in challenging applications. They have a sensitive composite element and are available in frequencies from 2.25 MHz to 15 MHz and in sizes from 3 mm (0.25 in.) to 12 mm (0.5 in.).
