Technology & Features
DU Dual-Element Transducers
Model DU are general purpose dual-element transducers with side-mounted Microdot connectors. Replaceable/interchangeable delay lines and cross-talk barriers greatly extend versatility, cost-effectiveness, service life and can be contoured to fit I.D. or O.D. curved surfaces.
Dual-element contacts are longitudinal-wave (straight beam) transducers designed for near-surface and thin range flaw detection and thickness measurement. Two elements, one transmitter and one receiver, are mounted at an included (roof) angle to improve signals-to-noise ratio and optimize near-surface resolution.
Thickness gauging on thick & thin parts
Near-surface and thin range flaw detection
Thickness gauging on pitted, curved, and irregular surfaces
*GP Series – General Purpose series of transducers are recommended for most applications and have a good trade-off between sensitivity and resolution. They have a medium frequency bandwidth of 40-65% at -6db but with more ring-down cycles in the waveform.
