Description

Die Erfindung bezieht sich auf ein Hochfrequenzvariometer, bei welchem sich die veränderliche Induktivitätswicklung .auf einem Massekern #ibefindet und die Indüktivität dieser Wicklung durch ein Gleichstromerregersystem beeinflußt wird.The invention relates to a high frequency variometer in which the variable inductance winding is located on a ground core #ib and the inductance of this winding is influenced by a DC exciter system.

Gemäß ider Erfindung wird als Werkstoff des ,E''rregersystems ebenfalls ein Massekernmaterial benutzt. Als Werkstoff für die magnetisierbaren Teilchen des Hochfrequenzmassekernes können vorzugsweise gleichartige Teilchen dienen, wie sie für das Erregersystem angeführt worden sind.According to the invention, the material of the "exciter system." a ground core material is used. As a material for the magnetizable particles of the High-frequency mass core can preferably serve similar particles as they for the pathogen system.

Bei den Anordnungen, auf die sich die vorliegende Erfindung bezieht, ist es häufig wünschenswert, dem Gleichfeld ein Wechselfelid zu Überlagern. In einem solchen Fall würde die Verwendung eines massiven oder eines aus einem lamellierten Blechkörper bestehenden Erregerjoches ergeben, daß das Wechselfeld durch die sich in diesem Erregerjoch ausbildenden Wirbelströme stark geschwächt wird und nicht in der notwendigen Stärke die veränderliche Induktivität beeinflußt.In the arrangements to which the present invention relates, it is often desirable to superimpose an alternating field on the constant field. In one such a case would be the use of a massive one or one made of a laminated one Sheet metal body existing exciter yoke show that the alternating field through the in this exciter yoke forming eddy currents is strongly weakened and not influences the variable inductance to the required extent.

In der Zeichnung ist ein Ausführungsbeispiel der @R;rfindung dargestellt.In the drawing, an embodiment of the invention is shown.

Das Erregerjoch i ibesteht gemäß der Erfindung aus Massekernmaterial. In einem Luftspalt dieses Erregerjoches befindet sich der aus einem Hochfrequenzmassekernstoff bestehende Kern 2. Auf dem Kern 2 ist idie veränderliche Induktivität 3 aufgebracht. Die Gleichstromerregerwicklüng ist mit q. bezeichnet. Durch diese Erregerwicklung wird ein Strom vorgegebener Größe hindurchgeschickt.According to the invention, the exciter yoke consists of a mass core material. The one made of a high-frequency core material is located in an air gap of this exciter yoke Existing core 2. The variable inductance 3 is applied to the core 2. The DC exciter winding is with q. designated. Through this excitation winding a stream of predetermined size is sent through.

Auf dem aus Massekernmaterial bestehenden Erregerjoch i befindet sich außerdem noch eine ,zweite Erregerspule 5, durch die ein Wechselstrom hindurchgeleitet wird, der das sich zu dem vorhandenen Gleichfeld addierende Wechselfeld ergibt.On the exciter yoke i, which is made of a mass core material, is located also a second excitation coil 5 through which an alternating current is passed which results in the alternating field adding to the existing constant field.
