AbstractA hard faced contact ultrasound transducer device for transmitting ultrasound pulses into a workstructure at temperatures substantially above room temperature comprises a ceramic protection block, a piezoelectric element bonded to the protecting block, a damping substrate adjacent the piezoelectric element, a ceramic clamping block with standoff portions that limit the approach of the clamping block toward the ceramic protecting block, and fasteners to draw the clamping block toward the protecting block forcing the damping substrate against the piezoelectric element and the protecting block.
