1. Field of the Invention
The invention relates to a device for performing a weight measurement in centrifuges.
2. The Prior Art
A centrifuge of this type, however without swivellable mounting, is known from U.S. Pat. No. 5,092,995 in the form of an invertible filter centrifuge. Swivellable mountings of apparatuses for the purpose of a weight measurement with force measurement elements are known from the Siemens pamphlet: "Preiswerte Behalterinhaltsmessungen mit Kleinlastzellen und Auswageeinrichtungen" (=Economical measurements of container contents with low-load cells and weighing means). Such arrangements for weight measurement were also already used in centrifuges of the type mentioned at the beginning. From DE-32 28 714 A1 it is ultimately known to equalize interfering forces caused by gas pressures in a weighing container by a compensation means such that the weight measurement remains unaffected. This known compensation means is, however, relatively complicated and requires, in particular, separate counter-pressure containers, which are connected with the weighing container by means of lines, as well as the diversion of a force from this counter-pressure container which equalizes the interfering forces. These additional apparatuses are relatively complicated and expensive.
