Abstract
In an ultrasound testing deivce for testing in particular test bodies in the form of railway tracks (4), probe elements (7) in the form of electromagnetic ultrasound transducers are arranged on a running tread (2) of a test wheel (1). When the running tread (2) runs on a running surface (3) of the railway track (4), the received echo signals can be evaluated in a control and evaluation circuit as a factor of the position of the test wheel (1) determined by a position detection device (15, 16, 17). This ultrasound testing device is characterized by the fact that the ultrasound test can be performed up to the close vicinity of the joint location and with a very low acoustic noise component at high tranlsation velocities of the test wheel (1) and even at railway track (4) joint locations having an offset.
