Weighing scale#Balance

A decimal scale (also scale Deka, Dezimalbrückenwaage or bag balance) is a weighing device to determine the weight of an unknown mass by direct comparison with the weight of a known mass. The unknown mass, the Wägeobjekt through, is a ratio of 10:1 for the known mass, the issued standard weights.

Description

Which has a decimal scale ungleicharmigen balance beam, wherein the portion of the beam, to the work, the standard weights placed ten times as long as the section, acts on the article to be weighed of which Wägeobjekt. Due to the lever principle therefore can be determined with the standard weights placed each ten times Wägemasse what with larger weight loads represents a significant improvement over the equal arm balance. With the decimal scale heavy objects can be weighed with only a few, relatively light weights. The decimal scale is the most familiar form of a weighbridge, where the Wägeobjekt on a platform ( bridge ) is placed. This platform is connected by a bottom beam as well as the intermediate and the supporting lever with the balance arm fixed to the frame of the balance.

History

The common in German-speaking decimal scale goes to the Benedictine monk Friedrich Alois Quintenz (* 1774 in Gengenbach, † 1822 in Strasbourg) back. Quintenz improved designed by the watchmaker Jean -Baptiste Schwilgué decimal weighbridge, by transferring the in - Schwilgué decimal scale or overhead bridge down. With the patent-pending in Strasbourg in 1821 Quintenz - decimal scale weight measure comparatively large masses was much easier, because now the heavy weighed no longer had to be lifted too.
