| Zusammenfassung: | A balance (1) has a weighing pan (3) that is held in a predetermined free-floating and constant position relative to translatory and rotary displacements in the six degrees of freedom during use. At least six position sensors are used to measure the position of the weighing pan in all three dimensions. A weighing mechanism having at least six electromagnetic mechanisms (5) generate compensation forces (Fc1-Fc6) that act on the weighing pan by sending currents through a force coil (7) associated with an associated permanent magnet. The weight of an object on the weighing pan is determined from the amounts of current flowing in the respective force coils to maintain the weighing pan in position. |
