Abstract
The invention relates to a measuring device for measuring the mass of a weight, comprising a main frame, a main beam supported on the main frame and comprising a central knife and two side knives parallel with the central knife; a balancing system loaded on one end of the main beam and comprising a set of counterweights; a weighting system loaded on the other end of the main beam; a weight transportation system capable of transporting and loading a standard weight or a test weight into the weighting system and capable of unloading and transporting them away from the weighting system; and a control system. The central knife and the two side knives are made from metal with a high temperature-cryogenic cycling process. The central knife and the two side knives are configured to be adjusted in parallelism with a three-coordinates measuring machine. The control system is adapted to control the balancing system and the weighting system to synchronously load or unload the balancing system and the weighting system.
