Anordnung zur Erzeugung von elektrischen Signalen mittels magnetfeldabhängigen Halbleiterbauelementen.Arrangement for generating electrical signals by means of magnetic field-dependent semiconductor components.
Die vorliegende Erfindung betrifft eine Anordnung zur Erzeugung von- elektrischen Signalen mittels magnetfeldabhängigen Halbleiterbauelementen, bei der auf einem Pol einet?

Fig. 4 eine Schaltung der Feldplatten der Anordnung nach Fig. 3.FIG. 4 shows a circuit of the field plates of the arrangement according to FIG. 3.
Bei der in Fig. 1 üsrgesteilten Ausführungsform der Erfindung iöx, auf einen Pol eines Magneten 1 ein Paar von Weicheisenpoischuhen 3,3' mittels einer Klebeschicht 2 aufgebracht. Auf der dea Magneten 1 angewandten Seite der Polschuhe 3j3' ist jeweils eine Feldplatte 4,4' vorgesehen. lier sich dabei ergebende, schcniatisch durch gestrichelte Linien 5i5' angedeutete Etreufluß vorläuft so, daß die beiden Feldplatten 4,4' gleichmäßig vormagnetisiert sind. Damit ergibt sich z.B. auch bei Temperaturänderungen oder bei Einflüssen von ütreufeidern eine gleichmäßige Änderung der Vormagnetisierung in beiden Feldplatten.In the embodiment of the invention shown in FIG. 1, a pair of soft iron pouches 3, 3 ′ are applied to a pole of a magnet 1 by means of an adhesive layer 2. A field plate 4, 4 'is provided on the side of the pole shoes 3j3' applied to the magnet 1. The resulting leakage flux, indicated in a technical manner by dashed lines 5i5 ', advances in such a way that the two field plates 4, 4' are uniformly premagnetized. This results in a uniform change in the premagnetization in both field plates, for example, even in the event of temperature changes or in the event of the influence of excess coils.
Bewegt man nun genäß der Aucführungsforir. nach Fig. 1 ein Weicheisenteil 6 oder eine Anordnung aus Y/eicheisenteilen an den Feldplatten 4,4' vorbei, so wird der Streufluß durch die flußlenkende Wirkung der Weicheisenpolschuhe 3,3' zu der Feldplatte geführt, der dem Weicheisenteil 6 gegenübersteht. Da nämlich der mittlere Abstand der Weicheisenpolschuhe 3,3' kleiner als die Zahnteilung der Zahnanordnung 6 ist, steht immer nur einer Feldplatte 4 bzw. 4' ein Zahn 7 der Zahnanordnung 6 gegenüber. Wenn insbesondere der Abstand der Mitten der Feldplatte^ 4,4* gleich der halben Zahnteilung der Zahnanordnung 6 ist, wird der Wirkungsgrad der Anordnung am größten. If one moves now according to the execution form. according to FIG. 1 Soft iron part 6 or an arrangement of Y / oak iron parts the field plates 4,4 'over, so the leakage flux is through the flux-directing effect of the soft iron pole pieces 3, 3 'to the field plate out, which faces the soft iron part 6. There namely the mean distance between the soft iron pole pieces 3.3 ' is smaller than the tooth pitch of the tooth arrangement 6, there is always only one field plate 4 or 4 ', a tooth 7 of the tooth arrangement 6 opposite. In particular, if the distance between the centers of the field plate ^ 4,4 * is equal to half the tooth pitch of the tooth arrangement 6, the efficiency of the arrangement becomes the greatest.

Changes in the resistances of the field plates 4, 4 ′ resulting from the movement of the soft iron part 6 can be picked up as signals in the liull branch of the bridge according to FIG. 2.
In Fig. 3j in der gleiche Teile vie in Fig. 1 mit gleichen Besugsze.i eben versehen sind, befinden sich auf dem zweiten Pol des Magneten zwei weitere Feldplatte 7,7', an denen ein weiteres Weicheisenteil 6' in der anhand von Fig. 1 beschriebenen V/eise vorbeibewegt wird.In Fig. 3j in the same parts as in Fig. 1 with the same Besugsze.i are just provided, are on the second Pole of the magnet two further field plates 7,7 'on which a further soft iron part 6 'is moved past in the manner described with reference to FIG. 1.
