A method for determining the rotational speed of ferromagnetic disks via the detection of permeability changes in dependence on radially directed forces in the disk includes orienting, for the measurement, at least one contactless-operating magneto-elastic sensor toward a face of the ferromagnetic disk to be measured, for detecting permeability changes in the case of occurring radial forces, and for calculating the radial forces from the permeability changes. The primary use is in the field of contactless determining data of rotating components. |
