An improved ultrasonic mechanical sector scanning transducer assembly is disclosed. An ultrasonic transducer is disposed for movement within a generally tubular housing. A drive element extends longitudinally within the housing and is coupled for transmitting motion to the transducer. Power means produces oscillatory rotative movement of the drive element and transducer. A diaphragm seal, comprising a resilient tubular membrane, provides a liquid tight seal between longitudinally displaced interior sections of the housing. The tubular membrane has one relatively narrow end and flares along its length to a wider opposite end. The narrow end is bonded about the drive element. The wider end is affixed about the periphery of the housing. A coaxial cable is coupled to the transducer and extends to the exterior of the housing. The cable is wrapped within a spiral groove extending about the outer surface of a spool or reel mounted for movement in unison with the transducer.
