ABSTRACT:
An automatic analytical balance is disclosed, which features a unique weighing structure. The scale comprises a flexibly pivotable shaft that pivots in one direction in response to a load being weighed, and that pivots in an opposite direction in response to a known movable weight movably disposed upon the shaft. A balance detector is operatively connected to the shaft to determine when the movement of the known weight has brought the shaft into a balanced condition. Means are provided to measure the movement of the known weight which is required to produce the balanced condition in the shaft. This measurement is indicative of the weight of the load being weighed.
