Description

Die vorliegende Erfindung bezieht sich -auf ein elektrisches Variometer- und insbesondere auf ein Mehrfachvariometer. Bei solchen elektrischen Mehrfachvariometern müssen zur Erreichung des Gleichlaufs zwischen den einzelnen Variometern Mittel zur Beeinflussung des Kurvenverlaufs vorgesehen werden, um Fertigungsstreuungen od. dgl. auszugleichen. Hierbei ist es vorteilhaft, daß die Charakteristik an möglichst vielen Punkten in Übereinstimmung gebracht werden kann, und daß vor allem die Gleichlaufe.instellung an einer beliebigen Stelle keine Änderung an einem anderen Kurvenpunkt zur Folge hat.The present invention relates to an electric variometer and in particular a multiple variometer. With such electrical multiple variometers Means must be used to achieve synchronization between the individual variometers can be provided to influence the course of the curve to avoid manufacturing deviations or the like to compensate. It is advantageous here that the characteristic is as close as possible many points can be brought into agreement, and that above all the synchronization at any point does not result in a change at any other point on the curve Has.

Gemäß der Erfindung ist zur praktischen Einhaltung des gewünschten Induktivitätswertes die Variometerspule mit einer zusätzlichen Induktivität zusammengeschaltet, die bei der Verstellung des die Variation bewirkenden Variometerteiles, das ist verstellbarer Massekern, bei Permeabilitätsabstimmung oder verstellbarer Wicklungsteil bei Koppl.ungsvariometern, in ihrem Wert um einen solchen Betrag schwankt, daß in jeder Variometerstellung - die resultierende Induktivität den gewünschten Wert erreicht. Als Gesamtinduktivität erhält man einen bestimmten Wert für jede Stellung des Variometers, wobei dieser Wert nach jeder Verstellung wieder erreicht wird. Die zusätzliche Induktivität kann sowohl in Reihe als auch parallel zur Hauptspule geschaltet werden.According to the invention, in order to practically comply with the desired Inductance value, the variometer coil is interconnected with an additional inductance, when adjusting the variometer part causing the variation, that is adjustable ground core, with permeability adjustment or adjustable winding part in coupling variometers, their value fluctuates by such an amount that in every variometer setting - the resulting inductance reaches the desired value. The total inductance is a certain value for each position of the variometer, this value is reached again after each adjustment. The additional inductance can be connected in series as well as parallel to the main coil.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Auf einer Achse i ist in bekannter Weise ein Tragarm 2 befestigt, an dem der Kern 3 angebracht ist. Der Kern 3 ist in üblicher Weise innerhalb einer Variometerspule q. durch Drehen der Achse i verstellbar. In Reihe oder parallel zu der Variömeterspule q. wird nun eine Zusatzinduktivität 5 geschaltet, die z. B. an dem nicht dargestellten Variometergehäusebefestigt ist. Auf der Variometerachse i sind über ein vorzugsweise scheibenförmiges Tragorgan 6 verstellbare Abgleichstifte 7, z. B. bestehend aus magnetisierbarem Pulverkernmaterial, angebracht, welche neben ihrer horizontalen Verstellbarkeit die Drehbewegung der Variometerachse i mitmachen.. Beim Vorbeischwenken vor der Zusatzinduktivität 5 bewirken die Massekerne 7 eine Induktivitätsänderung. Durch die .horizontale Verstellbarkeit der Massekernteile 7 kann nun die Induktivität der Zusatzspule 5 über dem Drehwinkel so verändert und eingestellt werden, daß die Abweichungen der Induktivitätswerte des Variometers vom Sollwert ausgeglichen werden.An exemplary embodiment of the invention is shown in the drawing. On an axis i, a support arm 2 is attached in a known manner, on which the core 3 is attached. The core 3 is in the usual way within a variometer coil q. adjustable by turning the axis i. In series or parallel to the variometer coil q. an additional inductance 5 is now switched, which z. B. on the not shown Variometer housing is attached. On the variometer axis i are preferably about a disc-shaped support member 6 adjustable alignment pins 7, z. B. consisting of magnetizable powder core material, attached which next to their horizontal Adjustability join in the rotation of the variometer axis i .. When swiveling past Before the additional inductance 5, the earth cores 7 cause a change in inductance. Due to the horizontal adjustability of the mass core parts 7, the inductance the additional coil 5 can be changed and adjusted over the angle of rotation so that the Deviations of the inductance values of the variometer from the nominal value are compensated.
