    摘要: An analytical balance that includes a balance scale, a wind guard encircling the balance scale, and an apparatus for generating an ionized stream of air for dissipating electrostatic charges of goods to be weighed. The apparatus for generating an ionized stream of air includes a blower that draws in air from the weighing space into at least one boundary surface of the weighing space. The blower also recycles the air back into the weighing space via at least one exhaust opening at another point. In this manner, highly effective dissipation of electrostatic charges is possible, and the stream of air can be conducted so that it exerts scarcely any vertical forces on the goods to be weighed. The analytical balance is very user-friendly in operation. Additionally, the apparatus for generating an ionized stream of air is preferably structured to be an easily installed optional component of the analytical balance.

    摘要: A top-loading balance with a housing, a weighing pan, and a load receptor, wherein the load receptor is connected with a system carrier by a parallel guidance having an upper guide and a lower guide. The system carrier is fixed relative to the housing. One of the guides is divided into two part-guides which, seen in plan view, are disposed preferably on either side of the undivided guide so that the guides do not overlap. In addition, the load receptor, the guides and the system carrier preferably form an integral component. The top-loading balance also includes strain gauges on at least one of the guides to generate a load-dependent electrical signal, which can be measured and converted into e.g. a visual display of the mass. The integral component has two cavities for batteries and the system carrier extends between the two battery cavities. Furthermore, the load receptor is constructed to be approximately U-shaped and the two limbs of the U are disposed laterally near the battery cavities. In addition, the strain gauges are arranged only on the inner side of the undivided guide. Therefore, the top-loading scale is flat and compact without compromising the stability of the scale. Preferably, the balance includes features, such as overload abutments, that protect the delicate parallel guidance, as well as features that ensure accurate measurement of off-center loads.
