ABSTRACT:
A clamp-on ultrasonic transducer assembly for making ultrasonic measurements on solid materials in a temperature far removed from ambient. An electroacoustic transducer is coupled to the solid surface through an elongated buffer element enclosed within a housing which is mechanically coupled to the buffer element only in the region of contact between the buffer and the solid material to be measured.
