This rotary probe has 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.

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
