Linearly Polarised Shear Wave

 
Linearly polarised bulk shear wave probe (LPS3035) for general purpose use, such as with Sonemat's GS2020 EMAT adaptor box system or Sonemat's PR5000 EMAT Pulser-Receiver.

Typical applications for this EMAT include: wall thickness measurements and acoustic birefringence measurement due to stress or texture.
