KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezweckt, ein elektromagnetisches Meßgerät für Gleich- und Wechselstrom von einfacher billiger Herstellungsart zu schaffen, das besonders als Tascheninstrument oder in ähnlicher Weise verwendet werden kann.The invention aims to provide an electromagnetic measuring device for direct and alternating current of simple, inexpensive production, especially as a pocket instrument or can be used in a similar manner.
Der Erfindungsgegenstand besteht aus zwei schalenförmigen, die Erregerspule einschließenden Polschuhen gleichen Durchmessers, vonThe subject of the invention consists of two shell-shaped enclosing the excitation coil Pole pieces of the same diameter, from
ίο denen der eine derart drehbar auf dem andern gelagert ist, daß die einander zugekehrten Ränder beider Polschuhe exzentrisch zur Lagerung liegen und bei Einwirkung der Erregerspule entgegen einer Federkraft zur Deckung zu kommen suchen.ίο which one so rotatable on the other is stored that the facing edges of both pole pieces are eccentric to Storage lie and when the excitation coil acts against a spring force to Seek cover to come.
In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar in Fig. r und 3 die untere feststehende Magnetschale, in Fig. 2 und 4 die obere drehbare Schale und in Fig. 5 und 6 das ganze Instrument.In the drawing, an embodiment of the subject matter of the invention is shown, and although in Fig. r and 3 the lower fixed magnetic shell, in Fig. 2 and 4 the upper rotatable Shell and in Fig. 5 and 6 the whole instrument.
Der äußere Mantel b der drehbaren Schale liegt schräg zur Achse c, und zwar so, daß der Mittelpunkt des unteren Begrenzungskreises in die Lagerachse c fällt. Zweckmäßig wird das Mantelstück b als besonderer Teil durch schrägen Abschnitt von einem Eisenzylinder hergestellt. Die untere Schale enthält den zentrisch zu ihr liegenden Elektromagnetkern und die Erregerspule i sowie die exzentrisch zu ihr angeordnete Lagerung α der oberen Schale.The outer shell b of the rotatable shell is inclined to the axis c, in such a way that the center of the lower boundary circle falls into the bearing axis c. The jacket piece b is expediently produced as a special part by means of an inclined section of an iron cylinder. The lower shell contains the electromagnet core lying centrically to it and the excitation coil i as well as the bearing α of the upper shell, which is arranged eccentrically to it.
Die Feder d, welche mit ihrem inneren Ende an der Achse c, mit dem äußeren an der Brücke h befestigt ist, bewirkt die Einstellung auf den Nullpunkt bei stromloser Erregerspule, wobei die Ränder e und f der beiden Polschuhe stark exzentrisch zueinander liegen. Die Skala kann auf der beweglichen Schale b selbst angebracht und der Zeiger feststehend angeordnet sein oder umgekehrt. Für verschiedene Meßbereiche können verschiedene Spulen i eingesetzt werden.The spring d, which is attached with its inner end to the axis c and the outer end to the bridge h , effects the adjustment to the zero point when the excitation coil is de-energized, the edges e and f of the two pole pieces being strongly eccentric to one another. The scale can be attached to the movable shell b itself and the pointer can be fixed or vice versa. Different coils i can be used for different measuring ranges.
