Large Angle Beam Transducers (European Standards) WB/WK and SWB/SWK Styles

WB/WK Series – Used for testing of large objects made of non-alloyed and low-alloyed steels (e.g. thick walled containers, axle shafts, all types of thick welds). WK probes generate very short echo pulses.

SWB/SWK Series – These probes are very versatile testing tools due to their good near resolution power and narrow beam spread. They enable to test small parts as well as large objects. The case dimensions are ideal for manual testing. The SWK probes generate very short echo pulses.
