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. 

Typical Applications

• Thickness gauging on thick & thin parts
• Near-surface and thin range flaw detection
• Thickness gauging on pitted, curved, and irregular surfaces

Series

*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.
