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 (SNR) and optimize near-surface resolution.
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.
