Panametrics-NDT Ultrasonic Transducers

We recommend the use of our SWC shear wave couplant for general purpose testing.

Normal Incidence Shear Wave Transducers

Single element contact transducers introduce shear waves directly into the test piece without the use of refracted wave mode conversion.

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 cas
  

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
