Abstract
The invention relates to a device, an arrangement and a method for characterizing the torsion, rotation, and/or positioning of a shaft by generating a periodic magnetic field of a magnetic field generator disposed between at least two magnetic field detectors by applying a periodic exciter signal. The field is modified by the shaft and induces an output signal at each of the magnetic field detectors. The difference with respect to amplitude or phase between the exciter signal and the first output signal is detected as a first measured variable and between the exciter signal and the second output signal is detected as a second measured variable. The total of and/or the difference between the first and the second measured variables is calculated, and the torsion, rotation, and/or positioning of the shaft is characterized based thereon.
