The invention relates to a transmitting system for the generation of ultrasonic waves for testing materials, comprising a controllable signal generator and an ultrasonic transducer, wherein the signal generator and the ultrasonic transducer are arranged in the immediate vicinity of one another, in order to provide a transmitting system for ultrasonic testing which has higher effectiveness and lower manufacturing costs than known transmitting systems.

System for transmitting ultrasonic waves

Apparatus for the bidirectional transfer of information comprises in each case: at least one rotating component (1); a further component (2); receivers (4, 5) on the respective components (1, 2), said receivers facing one another in groups on the axis of rotation (6) of the rotating component (1); and transmitters (7, 8) fitted on the components (1, 2) eccentrically with regard to the axis of rotation and directed towards the corresponding receivers (4, 5).
