Plate ultrasonic transducer BBND-GF

cylindricalcontact ultrasonicdirect-contact

Product Overview
The BBND-GF is an industrial contact ultrasonic flaw detection probe designed for nondestructive testing of plates, bars, profiles, forgings, castings, billets and other industrial components. Used with an ultrasonic flaw detector, it locates internal flaws, laminations, delaminations, inclusions and bond/interface anomalies. Multiple frequencies, element sizes, contact faces and connector options allow matching the probe to material, thickness, surface condition and access constraints.

Key Features

• General-purpose contact ultrasonic flaw detection for industrial components
• Suitable for internal flaw, lamination and bond/interface inspection
• Frequency options from 0.5 to 10 MHz
• Element diameters from 5 to 25 mm
• Contact-face options for regular, slightly curved or rough surfaces
• Probe body styles: standard, compact and fingertip
• Connector choices: Lemo 1, Lemo 00, BNC, Microdot; top or side orientation
