More Information
Summary:An ultrasonic transducer apparatus includes an emitter for emitting pulsed ultrasonic signals into a railroad wheel to be tested and at least one receiver for receiving the corresponding echo signals from the wheel. Transmission of the ultrasonic signals into the wheel as well as the return transmission of signals from the wheel to the receiver can be carried out in a contacting and/or non-contacting manner. The emitter (2) and the receiver (3) are arranged spaced apart from one another around the circumference of the railroad wheel (1), with a sufficient spacing distance that the receiver (3) is arranged outside of a symmetrical range (4) about the centerline (6) of the emitter (2) in which superposition of the two pulse packets of ultrasonic signals travelling around the wheel can arise.
