Direct-contact ultrasonic transducer

with delay lineshear wave

Single element normal incidence Shear Wave Transducers contact transducers introduce shear waves directly into the test piece without the use of refracted wave mode conversion. We recommend the use of our SWC shear wave couplant for general purpose testing. Advantages: • Generate shear waves which propagate perpendicular to the test surface • For ease of alignment, the direction of the polarization of shear wave is nominally in line with the right angle connector • The ratio of the longitudinal to shear wave components is generally below -30 dB Applications: • Shear wave velocity measurements • Calculation of Young's Modulus of elasticity and shear modulus (see Technical Notes, page 46) • Characterization of material grain structure Direct Contact Series • WC-5 wear plate increases durability and wear resistance • Available in both the Standard and Fingertip case styles • 303 stainless steel case Delay Line Series • Integral delay line permits measurements at higher frequencies • Fused silica delay line minimizes attenuation and provides physical protection to the crystal element
