Sonatest DEM and PDEM Dual Transducers

Sonatest DEM and PDEM Dual Transducers

Fingertip Dual Transducers for near surface resolution

Overview

The Sonatest DEM and PDEM Fingertip Dual Transducers are for corrosion thickness measurements on pipes and tanks to measure wall thickness and detect pitting corrosion. The DEM is medium damped and features semi-circular lead zirconate titanate crystal; the PDEM is also medium damped and features Piezo composite crystal.

Features

  • Dual normal beam compression wave contact transducers
  • Semi Circular lead zirconate titanate crystals (DEM)
  • Semi Circular Piezo composite crystal (PDEM)
  • Max operating temperature 50°C / 120°F
  • Medium damped for medium bandwidth
  • High Temperature options for max temperature operation at 285°C / 545°F

Applications

DEM and PDEM Transducers are used for general non destructive testing purposes. High temperature models are available for the DEM. Common Applications include:

  • Thickness inspection
  • Casting Inspection for near surface flaws
  • High temperature inspection (DEM)
