A radially polarised shear bulk wave EMAT (HWS2225-GC) for general purpose use,
such as with Sonemat's GS2020 EMAT adaptor box system or Sonemat's PR5000 EMAT Pulser-Receiver.
Type: Pulse-echo Working Principle: Lorentz (will also use magnetostrictive effect if available). Wave Type: Normal incidence, centro-symmetric radially polarised bulk shear wave. Excitation Frequency: Broadband (spike), optimised for peak energy around 5 MHz. Working Voltage: 400 V - 1000 V. Magnet Type: Single Neodymium Iron Boride (NIB) magnet; working field normal to sample. Connector: BNC Standard 50
Ω. Temperature Range: 0 - 80
°c. Recommended Driver: Sonemat GS2020 EMAT adaptor box with any modern flaw detector, or Sonemat PR pulser-reciever. Options: High temperature and high signal variants are available. Price: £500
