Abstract: | Balances destined for weighing of goods in vacuum are labeled as vacuum balances. Macrobalances are designed for loads above 100 g. For comparison of mass prototypes without influence of buoyancy, vacuum mass comparators were designed. Large vacuum balances are used for the determination of the specific or the atomic mass of gases. Electromagnetic vacuum precision balances are used to investigate chemical reactions at reduced gas pressure and for thermogravimetric analysis. Production processes can be controlled by means of load cells of various design. |
