Normal Incidence Shear Wave Transducers

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.

Overview
Direct Contact Series
Delay Line Series

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
