  • FIG. 1 shows a schematic sketch of a lateral perspective view of an arrangement with an embodiment of the sensor device according to the invention. Shown is a sensor device 1 in the form of a arranged in the region of a rail 100 wheel sensor. In this case, the sensor device 1 is arranged on the inside of the rail and aligned with respect to their detection area in such a way that it detects the wheel flange or the running surface of the sensor device 1 or moving past the sensor device 1 iron wheels of rail vehicles.
  • the sensor device 1 comprises two sensor units 10 and 20, each having two receiving coils 12, 13 and 22, 23. Relative to a given by the rail longitudinal direction of movement 5 is between the receiving coils 12, 13 and 22, 23 each have an AC-powered transmitting coil 11 and 21 respectively.
  • the transmitting coils 11, 21 are arranged such that their longitudinal axes 11a, 21a are aligned parallel to the direction of movement 5 and thus perpendicular to the longitudinal axes 12a, 13a, 22a, 23a of the receiving coils 12, 13, 22, 23.
  • the transmitting coils 11, 21 and the receiving coils 12, 13, 22, 23 of both sensor units 10, 20 with respect to the direction of movement 5 each spaced behind the other, ie in the rail longitudinal direction seen "in a row" are arranged.
  • the transmitting coils 11, 21 Due to the orientation and arrangement of the transmitter coils 11, 21, these generate magnetic fields or magnetic fluxes 60, 70, which run essentially horizontally along the rail 100. Due to the orientation of the longitudinal axes 12a, 13a, 22a, 23a of the receiving coils 12, 13, 22, 23, which are perpendicular to the direction of movement 5, the transmitting coils 11, 21 thus induce voltages in the respective receiving coils 12, 13 and 22, 23, respectively Field distorting materials due to the location of the receiving coils 12, 13, 22, 23 in the middle of the magnetic fields or magnetic fluxes 60, 70 would be extremely low. However, the rail head 110 of the rail 100 causes a field distortion, through which a Feldunsymmetrie arises which leads to receiving signals of the receiving coils 12, 13, 22, 23 in the form of a signal arresting voltage without being influenced by a passing wheel.
  • the signal voltages detected by the receiving coils 12, 13 or 22, 23 and caused by the magnetic fluxes 60, 70 advantageously add up.

  • the left sensor unit 10 When passing movement or passage of a wheel in the direction of movement 5, ie in this case from left to on the right, the left sensor unit 10 will first generate a received signal. If the wheel continues to roll, the field of the transmitting coil 21 of the right-hand sensor unit 20 is also increasingly distorted as a result. However, this field distortion additionally influences the received signal or the received voltage in the right receiver coil 13 of the left sensor unit 10 in such a way that the amplitude of the received signal, ie the received voltage, increases and the received signal as such therefore remains longer overall or decreases comparatively slowly when the wheel is traveling.
  • This effect is advantageously symmetrical to the effect that an object moving past the sensor device 1 in the form of the wheel in the middle of the sensor device 1 respectively increases the reception voltages of the central receiver coils 13, 22 with the participation of magnetic fields or magnetic fluxes 60, 70 of both transmit coils 11, 21 leads.

As a result, a further increase in the signal overlap of the two sensor units 10, 20 is achieved.
  • the receiving coils 12, 13 and 22, 23 of the respective sensor unit 10 and 20 are arranged symmetrically relative to the transmitting coil 11 and 21 of the respective sensor unit 10 ,.20 relative to the movement direction 5.
  • a corresponding symmetrical arrangement is advantageous both in terms of the space required by the sensor device and in terms of its flexible applicability.
  • the sensor device 1 has a housing 30 enclosing both sensor units 10, 20.
  • the receiving coils 13 and 22 arranged between the transmitting coils 11, 21 of the two sensor units 10, 20 it should be noted that in principle the position of these two receiving coils 13, 22 could be interchanged with one another.
  • the sensor unit 10 would thus comprise the receiver coils 12 and 22 and the sensor unit 20 would comprise the receiver coils 13 and 23, ie the two sensor units 10, 20 would "overlap" relative to the direction of movement 5, ie in the present case the rail longitudinal direction.
  • a corresponding permutation of the position of the receiving coils 13, 21 is possible because the opposite orientation of the magnetic fluxes 60, 70 of the transmitting coils 11, 21 for the respective receiving coils 13, 22 results in received signals in the form of voltages with the same sign. This advantageously makes it possible, depending on the particular circumstances and requirements to vary the overlap of the receiving voltages of the receiving coils 12, 13, 22, 23.
  • the sensor units 10 and 20, as an alternative to the representation of the FIG. 1 could also be inclined or tilted to the rail 100. In this case, therefore, the entire system comprising the transmitting coils 11, 21 and the receiving coils 12, 13, 22, 23 would be arranged rotated about an axis parallel to the rail longitudinal direction.
  • the transmitting coils 11, 21 and the receiving coils 12, 13, 22, 23 are advantageously completely free of ferromagnetic materials, i. as air coils, built.

  • the sensor unit 10 comprises analogous to the representation of FIG. 1 a transmitting coil 11 and two receiving coils 12 and 13.
  • the receiving coils 12, 13 in this case connected in series with each other in series, so that the individual received signals of the two receiving coils 12, 13 subtract and can be tapped as a signal voltage U.
  • the signal voltage U is fed to an evaluation device 40, which is spaced from the sensor unit 10 in a separate Housing 50 is arranged, which may be part of a track connection housing, for example.

Furthermore, advantageously, the subtraction of two received signals or voltages of different sign per sensor unit 10, 20 and the additional influence of the adjacent sensor unit 10 or 20 on the respective received voltage causes the field deflection caused by a passing or approaching object to be exploited several times. This has an advantageous effect on the overall signal course of the sensor device 1 in that it has an increased sensitivity.
  • the field compensating structure of the sensor device 1 with transmitting coils 11, 21 and receiving coils 12, 13, 22, 23 advantageously also increases the immunity to interference with respect to external sources.
