angle beam transducers, contact probes, ultrasonic testing, flaw detection, krautkramer

Ultrasonic Contact Probes, for flaw detection and sizing.

Ultrasonic angle beam transducers are preferred for parts with inclined flaws, such as welds, and are sometimes used in mechanized or automated testing. They use refraction to transmit shear or longitudinal waves at a predetermined angle, while most standard transducers generate shear waves by mode conversion. Elements are mounted on integral or replaceable wedges, requiring a couplant layer, typically a gel, oil or paste.

Our angle beam probes are available in both single and dual element types, and in multiple sizes.
