Description

Luftdämpfung für hochempfindliche Meßinstrumente Als Luftdämpfung für hochempfindliche Meßinstrumente ist bereits vorgeschlagen worden, lange, dünne Körper, die unterhalb einer bestimmten Größe einen im Verhältnis zu ihrem Gewicht hohen Bewjegungswiderstand in Luft erfahren, am beweglichen Organ des Meßinstruments zu befestigen, wodurch ohne die sonst üblichen Luftkammern und bei nur -unbedeutender Gewichtsbelastung des bejeglichen Organs eine ausreichende Dämpfung erzielt wird. Bei Zeigerinstrumenten kann nach demselben Vorschlag sinngemäß der Zeiger für die Dämpfung herangezogen werden.Air damping for highly sensitive measuring instruments As air cushioning for highly sensitive measuring instruments have already been proposed, long, thin bodies, those below a certain size are high in relation to their weight Experience resistance to movement in air at the moving organ of the meter fasten, whereby without the otherwise usual air chambers and only insignificant Weight load of each organ sufficient damping is achieved. In the case of pointer instruments, the pointer for the Attenuation can be used.

Gemäß der Erfindung ist aus mehreren für die Dämpfung vorgesehenen langen, dünnen Körpern ein für die Ablesung erforderlicher Zeiger so aufgebaut, daß eine genügende Steifigkeit in zwei zueinander senkrechten Richtungen erzielt wird. According to the invention, several are provided for damping long, thin bodies a pointer required for reading is constructed in such a way that that a sufficient rigidity is achieved in two mutually perpendicular directions will.

Im allgemeinen kann durch Verwendung von drei solchen stabförmigen Körpern, deren Durchmesser zur Erreichung der gewollten Dämpfung nicht größer als 0,07 mm sein darf, sowohl Höhenals auch Seitensteifigkeit des Zeigers in genügendem Maß erzielt werden. In general, by using three such rod-shaped Bodies whose diameter to achieve the desired damping is not greater than 0.07 mm, both height and lateral stiffness of the pointer are sufficient Degree can be achieved.

Ein solcher Verband von den Zeiger bildenden Stäbchen führt durch sein geringes Gewicht und seinem trotzdem verhältnismäßig hohen Luftwiderstand eine hohe Dämpfung herbei. Such a bandage of small sticks forming the pointer leads through its low weight and its relatively high air resistance high attenuation.
