Dämpfungseinrichtung für elektrische Meßinstrumente. Patentiert im Deutschen Reiche vom 29. März 1904 ab. Damping device for electrical measuring instruments. Patented in the German Empire on March 29, 1904.
Durch vorliegende Anordnung werden die Schwingungen des Zeigers elektrischer Meßinstrumente gedämpft, so daß das Instrument fast aperiodisch ist.With the present arrangement, the oscillations of the pointer of electrical measuring instruments attenuated so that the instrument is almost aperiodic.
An dem Zeiger α befindet sich die kleine Trommel b. Diese Trommel b be\vegt sich in dem als Gefäß ausgebildeten unteren Lagere. Der Zwischenraum zwischen Trommel b und der inneren Wand des Lagers c ίο ist so gering, daß die zur Dämpfung der Zeigerbewegungen in das untere Lager c eingebrachte Flüssigkeit infolge der Adhäsion nicht aus dem Gefäß auslaufen kann, gleichviel in welcher Lage oder Stellung sich das Instrument befindet. Der Rand der Trommel b hindert das Hereinfallen von Schmutz in das untere Lager c, und zwar hauptsächlich während der Arbeit.At the pointer α is the small drum b. This drum b moves in the lower bearing designed as a vessel. The space between the drum b and the inner wall of the bearing c ίο is so small that the liquid introduced into the lower bearing c to dampen the movements of the pointer cannot run out of the vessel due to the adhesion, regardless of the position or position of the instrument . The edge of the drum b prevents dirt from falling into the lower bearing c, mainly during work.
