Abstract
Proposed is a compensation scale (10) in which at least one acceleration sensor (24, 25) is disposed at a movable component (14) of the scale (10) and puts out a signal to a correction signal processing arrangement (50) which determines at least one correction signal (53, 54, 56) for influencing the measuring result that appears at the output (43) as a measure for the weight or the mass (m) of the load (15) with which the movable component (14) was charged. The correction signals (53, 54, 56) eliminate the influence of translatory and rotatory interference accelerations (y, .THETA.) which act on the base plate (11) of the scale and, without being corrected, would falsify the measuring result (43) or at least unduly extend the measuring time.
