Model DU Dual-Element Contact 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 signal-to-noise ratio and optimize near-surface resolution.
