Cylindrical ultrasonic transducer BBND-AI

platemulti-transducerpiezoelectric

Product Overview
The BBND-AI is designed for automated, mechanized and water-coupled ultrasonic NDT systems. It integrates with immersion tanks, scanning mechanisms, production lines, water-jet coupling systems and dedicated fixtures. Typical targets include plates, tubes, bars, composites, contoured components and large-area structures. Non-focused, point-focused, line-focused and phased-array configurations are available to match inspection area, expected flaw size, component curvature, scanning speed, coupling method and system interface.
