DEM & PDEM


Overview

Twin Compression Dual Element.

DEM

Twin crystal contact compression probe with a medium bandwidth. Stainless steel housing to protect the acrylic face from overwear.

PDEM

The PDEM offers the same characteristics as the DEM but with improved resolution and sensitivity.

Features

  • Lead metaniobate crystal (DEM)
  • Composite PZT (PDEM)
  • Medium damped for medium bandwidth
  • Peek face
