Product Overview
The BBND-GF is designed for ultrasonic nondestructive testing of plates, bars, profiles, forgings, castings, billets, and industrial components. Used with an ultrasonic flaw detector, it supports the detection of internal flaws, laminations, delamination, inclusions, and bonding irregularities. It is also suitable for routine inspection of thick sections and materials that are difficult to penetrate.
Multiple frequencies, element sizes, contact faces, and connector arrangements are available to match the test material, component thickness, surface condition, inspection depth, and access space.
Key Features
- General-purpose ultrasonic flaw detection for industrial components
- Suitable for internal flaws, lamination, and bond inspection
- Frequency options from 0.5 to 10 MHz
- Element diameters from 5 to 25 mm
- Options for regular, slightly curved, and rough contact surfaces
- Standard, compact, and fingertip configurations
