Rotary Probe Systems

Rotating the ultrasonic transducers around a pipe/bar using a rotary probe offers distinct advantages over the more conventional methods of rotating or spiralling the product under test; notably High throughput test speed, on line location, multi-orientational testing (i.e. longitudinal, transverse, oblique defects or imperfections), simpler tube handling system and faster size change operations. All unicorn rotary probes utilize hydrostatic bearings which offer high load carrying characteristics and virtually no bearing wear. Rotary probes, of this type, have been utililized reliably over many years in an industrial environment.

The rotary head's mechanics can be supplied either separately or as part of a system package which includes the processing electronics and, if required, the conveyor / tube handling mechanics.

  • Overview of Annular Chamber Rotary Test Head Systems Open or Close

    The following rotary probes have adjustable angle transducers housed in an annular chamber. In operation, the annular chamber is maintained full of water and the tube passes through close tolerance inlet and outlet guides.

  • Overview Contact Shoe Rotary Test Head Systems Open or Close

    The following rotary probes utilise the contact shoe principle which provides an advantage over the annular chambers in that much larger tube off-centre conditions can be tolerated (typically 6mm) and with a special, automatic, probe shoe lift mechanism, most tube end conditions can be accommodated. This type of rotary probe can be used in on-line situations testing tubes/bars with un-cut ends straight from the production mill.
