摘要

The wheel sensor has an inductive sensor (1) for detecting a magnetic field change as a result of the iron wheels of a rail vehicle. The inductive sensor is arranged at a side of a rail (2) of the track. The inductive sensor comprises a transmitting coil (4) and two receiving coils (5,6). The receiving coils have adjacent partial coils (5.1,5.2,6.1,6.2) connected in series in anti-phase. The partial coils are parametrized identically.
