Abstract

A device operated by a vehicle to generate presence data and/or direction and/or speed criteria in predetermined areas along tracks, where, in predetermined areas, the magnetic fields generated by transmitter coils powered by ac (alternating current) induce different amplitude and phase voltages in the receiver coils in response to vehicles moving through these areas. These voltages are processed by means of electronic evaluation devices in said criteria and data for vehicles. Characterized in that at least one transmitter coil (S, Fig. 1) and one receiver (E), which consist of partial windings (El and Er), are located on a common ferrite core (K) in such a way that, in the uninfluenced situation of the device, the sum of all the components of the resulting magnetic field enclosed in the receiving coil is almost zero, and that, due to the field distortion that occurs when a vehicle exerts its influence on the device, the sum of all the components of the resulting field is non-zero.
