ABSTRACT:
A wheel probe for ultrasonically inspecting a component, such as the wall of a pipe, is of hollow form to define a chamber in which at least one ultrasonic transducer is supported to direct and receive ultra-sound through the wheel probe. The chamber is filled with an acoustic coupling liquid, and at least one resilient diaphragm is provided in the wall of the chamber so as to deflect in response to a difference in pressure thereon and balance the pressure of the liquid with that of the environment about the wheel probe.
