Product Information

These probes are designed to fit on removable wedges. Refracted shear wave angles may be specified as required.

The AWS series are designed to meet or exceed all of the requirements outlined in AWS Structural Welding Code D1.1.

All SWS and AWS transducers utilize captive screws for fastening the probe to the wedge and have top-mount BNC connectors. High temperature wedges are for temperatures up to 400° F (205 °C).

Benchmark series SWS and AWS Style Angle Beam Transducers feature proprietary BENCHMARK COMPOSITE active elements. They are available in the same range of sizes and fit the same removable wedges as the Gamma series. Benchmark series offer a superior combination of sensitivity, resolution, and penetration for punching through highly attenuative materials. They are especially beneficial when signal to noise ratio is a problem, for example coarse grain materials and fiber reinforced composites.
