Abstract
A wheel-type inspection device includes within the wheel structure a sensor head. The sensor head carries both ultrasonic transducers and a surface tracking structure maintained at fixed distance relative to the transducers. In operation, the surface tracking structure remains against the inner surface of the tire and thereby maintains a fixed distance between the transducers and the surface of the work piece under inspection. As a result, reflected sound energy analysis need not compensate for variations in distance between the transducers and the work piece because no such variations in distance occur under the disclosed device.
