Abstract

A high-temperature transducer for transmitting and/or receiving sonic energy having a housing with a cylindrical opening, a metallic acoustic window element closing one end of the opening, a cylindrical transducer crystal having one planar surface in engagement with the acoustic window rearward face, a cylindrical dampening member in contact with the crystal rearward face, a first and a second thrust disc received in the cylindrical opening with a thrust transmitting sphere between the discs, and a thrust producing compression screw threadably received in the cylindrical opening supplying pressure against the first of the thrust discs which pressure is applied by means of the sphere to the second thrust disc, to the dampening means and to the crystal rearward face to force the crystal into intimate engagement with the acoustic window for effective sound transmission.
