Method for monitoring and/or testing without destruction a transmission element, and measuring arrangement for carrying out the method

The invention relates to a method for monitoring and/or testing without destruction a transmission element having at least one magnetizable tie beam, and to a measuring arrangement for carrying out the method. The method is distinguished by the fact that a single-axis or multiple-axis measurement of the magnetic field which is disrupted by the tie beam is carried out, by at least one magnetic field sensor or an arrangement of a plurality of magnetic field sensors being guided relative to the transmission element or by the transmission element being guided relative to the measuring arrangement, and by the detected measured signals being evaluated by way of a data acquisition and evaluation device, preferably with regard to an anomaly of the detected magnetic field.
