Angle Bean Transducers

Single Angle Shear Wave (SAO)

Features

Medium damped, lead zirconate titanate (PZT) elements tuned to provide optimum gain and resolution for general use.  
Housed in a stainless steel case with the emission point close to the front edge, enabling closer access to the weld cap without affecting the beam and covering even a greater area of the weld under inspection.  
Casing scaled in millimetres from the front of the transducer.  
Ergonomically designed for fatigue free scanning and ease of handling.  
A centre line mark for length measurement provides consistency and accuracy when sizing defects.  
Colour coded labels enable recognition of the angle.  
Acrylic wear plates allow shaping for curvature or repair when worn.  
Sets of 10 plexiglass wear plates 2 mm thick (plus acoustically matched adhesive) are available as a kit and can be ordered separately: code SASK 10/2
