Description

Elektrisches Dreheisen-bleßgerät Bei Dreheisen-Meßgeräten wird die Lage des auf ;der Zeigerwelle sitzenden EiseÜblättchens, also der Zeigerausschlag, bestimmt von derRichtkraft des .durch denElektromagneten erzeugten Feldes und von der ihr das Gleichgewicht haltenden Kraft, die vom Felle des Dauermagneten herrührt. Beide Magnete sind in der Regel so angeordnet, däß die Achsen ihrer Felder aufeinander senkrecht stehen.Electric moving-iron bleeding device With moving-iron measuring devices, the Position of the ice sheet sitting on; the pointer shaft, i.e. the pointer deflection, determined by the directional force of the field generated by the electromagnet and by the force that holds it in balance, which comes from the head of the permanent magnet. Both magnets are usually arranged so that the axes of their fields are on top of each other stand vertically.

Die Nullstellung des Zeigers, dieVerteilung der Skalenwerte und der Endwert hängen, abgesehen von anderen Dingen, auch von der Lage der Feldachse des Dauermagneten gegenüber derjenigen des Elektromagneten ab. Um die Nullstellung :des Zeigers, die Verteilung,der Skalenwerte und den Endwert in dem gewünschten Sinne uni' auf leichte Weise beeinflussen. zu können, wird erfindungsgemäß der Dauermagnet beweglich angeordnet, und zwar so, idaß er in. seinem neutralen Punkt auf einem Niet sitzt, der das eine Lager der Zeigerwelle bildet, un-cl um diesen :Niet innerhalb eines gewissen Bereiches mit Zwang gedreht werden kann.The zero position of the pointer, the distribution of the scale values and the Apart from other things, the final value also depends on the position of the field axis of the Permanent magnets compared to that of the electromagnet. To reset: des Pointer, the distribution, the scale values and the final value in the desired sense uni 'influence in a light way. to be able to, according to the invention, the permanent magnet movably arranged, in such a way that it is in its neutral point on one The rivet, which forms the one bearing of the pointer shaft, sits un-cl around this: rivet within a certain area can be rotated with force.

Der Aufbau eines solchen Meßgerätes ist schematisch in Abb. i von vorne und in Abb. a im Schnitt dargestellt. Darin bedeutet a den Zeiger und b die Zeigerwelle, die mit ihren beiden Spitzen in den Vertiefungen der in (-lern :Messingrahmen c festsitzenden Schraube d und des Nietes e gelagert ist. Der Rahmen c ist in der Gehäuserückwand befestigt. Auf dem Niet e sitzt außerhalb des Rahmens der U-förmige Dauermagnet f. Seine beiden Schenkel liegen p.arwllel zur Zeigerwelle. Zwischen seinen Polen g und lt befindet sich das auf der Zeigerwelle festsitzende Eisenblättchen i. Die magnetische Achse des Elektromagneten h bildet mit der Zeigerwelle einen rechten Winkel.The structure of such a measuring device is shown schematically in Fig. I of shown in section in front and in Fig. a. Here a means the pointer and b the Pointer shaft, which with its two tips in the recesses of the in (-lern: brass frame c tight screw d and the rivet e is mounted. The frame c is in the Case back wall attached. The U-shaped one sits on the rivet e outside the frame Permanent magnet f. Its two legs are p.arwllel to the pointer shaft. Between at its poles g and lt is the iron sheet that is stuck to the pointer shaft i. The magnetic axis of the electromagnet h forms one with the pointer shaft right angle.
