Abstract
A contact ultrasonic transducer head assembly. A stationary housing is adapted to be fitted to a remotely operated manipulator. A movable assembly slidably received by the stationary housing has a plurality of independently suspended ultrasonic transducers mounted thereon. A position encoder mounted in the movable assembly monitors movement within the stationary housing. A limit switch is used to electrically disable the remotely operated manipulator when the movable assembly slides a predetermined distance into the stationary housing to prevent damage to the transducers or the surface being inspected.
