Title:
A HIGH ACCURACY MEASURING DEVICE FOR MEASURING LARGE MASS
Document Type and Number:
WIPO Patent Application WO/2018/040135
Kind Code:
A1
Abstract:
A measuring device for measuring the mass of a weight, comprising a main frame(100), a main (beam 200) supported on the main frame (100) and comprising a central knife (201) and two side knives (202, 202') parallel with the central knife( 201); a balancing system (300) loaded on one end of the main beam (200) and comprising a set of counterweights (301); a weighting system (400) loaded on the other end of the main beam (200); a weight transportation system (500) capable of transporting and loading a standard weight (503) or a test weight (504) into the weighting system (400) and capable of unloading and transporting them away from the weighting system (400); and a control system (600). The central knife (201) and the two side knives (202, 202') are made from metal with a high temperature-cryogenic cycling process. The central knife (201) and the two side knives (202, 202') are configured to be adjusted in parallelism with a three-coordinates measuring machine. The control system (600) is adapted to control the balancing system (300) and the weighting system (400) to synchronously load or unload the balancing system (300) and the weighting system (400).
