Ultrasonic-Transmission Testing Device

Abstract

Ultrasonic-testing apparatus measures transmission through component under inspection. Includes hand-held ultrasonic transmitter placed on one side of component and ultrasonic receiver placed on other side. However, no need to hold or manually align receiving transducer after initial setup. Transmitter loosely inserted in magnetic assembly on one side, while receiver placed in another magnetic assembly on other side. Magnetic coupling keeps transmitter and receiver assemblies pressed against component and keeps receiver alligned with transmitter as transmitter scans across surface of component. Receiver moved to locations otherwise inaccessible.
