Abstract
Description
Es ist bekannt, für die Messung kleiner Massen (bzw. Massendifferenzen) oder Kräfte (bzw. Kraftdifferenzen) hochauflösende Präzisionswaagen oder speziell auf den Verwendungszweck zugeschnittene Vorrichtungen (z. B. Drehwaage nach Coulomb) zu verwenden.It is known to measure small masses (or Mass differences) or forces (or force differences) high resolution precision scales or especially on the Devices tailored to the intended use (e.g. Rotary balance according to Coulomb) to be used.
Nachteilig ist der technische Aufwand zur Herstellung von Präzisionswaagen und Spezialvorrichtungen und die oft umständliche Handhabung (z. B. Drehwaagen, Stromwaagen).The technical outlay for production is disadvantageous of precision scales and special devices and the often cumbersome handling (e.g. rotary scales, Power scales).
Insbesondere hat die Drehwaage nach Coulomb gravierende Mängel: Für genaue Messungen muß sie zeitaufwendig aus balanciert und mit einer geeichten Skala versehen wer den; größere Drehwinkel müssen kompensiert werden; bis weilen ist eine genaue Messung unmöglich, weil die La dungen abnehmen und der Meßvorgang zu lange dauert.In particular, the rotary scale according to Coulomb has serious Defects: For accurate measurements, it must be time-consuming balanced and provided with a calibrated scale the; larger angles of rotation must be compensated; until an exact measurement is impossible because the La take off and the measuring process takes too long.
Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die Empfindlichkeit einer Universal waage (z. B. einer elektronischen Küchenwaage) mit Hilfe einer einfachen Vorrichtung so weit zu steigern, daß die gewünschte Messung mit der Kombination Waage/Vor richtung ermöglicht wird.The invention specified in claim 1 is Underlying problem, the sensitivity of a universal scale (e.g. an electronic kitchen scale) with the help to increase a simple device so far that the desired measurement with the combination scale / pre direction is made possible.
Dieses Problem wird durch das im Patentanspruch 1 auf geführte Merkmal gelöst.This problem is solved by the in claim 1 guided feature solved.
Die mit der Erfindung erzielten Vorteile bestehen ins besondere darin, daß die Empfindlichkeit einer Univer salwaage mit einfachen Mitteln um Zehnerpotenzen (z. B. 10²) gesteigert werden kann.The advantages achieved with the invention are special in that the sensitivity of a Univer salwaage with simple means around powers of ten (e.g. 10²) can be increased.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Die Weiterbildung nach Patentanspruch 2 verhindert eine Überschreitung des Meßbereichs der eingesetzten Universalwaage. An advantageous embodiment of the invention is in Claim 2 specified. Continuing education after Claim 2 prevents exceeding the Measuring range of the universal scale used.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 3 angegeben. Die Weiterbildung nach Patentanspruch 3 verkürzt die Dauer des Meßvorgangs.Another advantageous embodiment of the invention is specified in claim 3. Continuing education according to claim 3 shortens the duration of the measurement process.
Ein Ausführungsbeispiel der Erfindung zur Messung Coulombscher Kräfte ist in der Zeichnung dargestellt. Es hat nicht die beschriebenen Mängel einer Coulombschen Drehwaage. Es bedeuten:An embodiment of the invention for measurement Coulomb forces are shown in the drawing. It does not have the described defects of a Coulomb Rotary balance. It means:
