A SIGMA Bore Probe is an ultrasonic inspection apparatus in which a
variety of transducers can be included. One SIGMA Bore Probe can perform
multiple inspections simultaneously: in the axial and circumferential
directions for the O.D. and I.D., including the I.D. surface with a
creeping wave, while measuring wall thickness.
Bore Probe has no absolute dimensions, the diameter can be changed to
accommodate various bore dimensions, the body length can be changed
to add more transducers. The limitations are based on the law of physics
and the imagination.
Bore Probe can be designed to contain refracting wedges which are held
in contact against the I.D. by integral opposing ball plungers, or contain
immersion facets and lenses which are held centered in the bore by radially
mounted integral ball plungers. Flooding the bore with water normally
fulfills the coupling requirements.
