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 ADP Dual-Element Contact Transducers Model ADP are small-diameter, low-profile transducers with 2 fixed co-axial cable and BNC connectors*. They are especially suitable for flaw detection and thickness measurement on pitted, curved, and irregular surfaces. Because the elements are mounted on internal delay lines they can be contoured to fit I.D. or O.D. curved surfaces.
