Abstract (en)

[origin: WO2009098101A1] The invention relates to a method for increasing the interference resistance of a wheel sensor, in particular for a track clear detection system, wherein a transmission signal (13) is produced in at least one sensor channel, said signal being inductively coupled (4) to a reception signal (5) that is fed to an evaluation device (10) for detection of a magnetic field change as a result of a railway vehicle having traveled over the track (3), and a corresponding wheel sensor. In order to counteract the interference effect using eddy current braking, it is provided that a level separation between a utility signal to be evaluated and an interference signal is maximized in relation to a phase difference (16) between the transmission signal (13) and the reception signal (5), said difference being specific to the interference signal.
