11st, the generator of 21 offer alternating currents is connected, for intuitive reason in Fig. 1 without display generator.
When wheel is passed over or through along the direction of motion 5, that is, when moving from left to right here, the sensor in left side
Unit 10 produces first receives signal.If wheel is rotated further, result causes the transmission line of the sensor unit 20 on right side
Also more and more consumingly distort the field of circle 21.However, the right side that this field distortion additionally influences left sensor unit 10 connects
Reception signal or receiving voltage in take-up circle 13 so that receive the amplitude rise of signal i.e. receiving voltage and thus
This reception signal is set to keep the longer time on the whole when wheel passes through or relatively slowly reduce.This effect is advantageously
It is symmetrical so that the object for the wheel form passed through from the side of sensor device 1 causes respectively in the center of sensor device 1
The situation that the receiving voltage of middle receiving coil 13,22 participates in the magnetic field of two transmit coils 11,21 or magnetic flux 60,70
Lower rise.It is combined with the raising for receiving signal, consequently leads to the raising of the Signal averaging when wheel passes through.This is exactly believing
Number level is favourable when smaller, because thus avoid due to interference caused by the very few superposition time.Last this to pass
Sensor arrangement 1 also can particularly securely be detected under hard situation by two sensor units 10,20 it is close or
The wheel that moves across and the especially direction of motion 5 of relevant wheel.
