ABSTRACT:
A scale of the platform type includes a base frame, a lever mechanism for force-transmission connected to the base frame, and including a plurality of two-armed levers, a weighing platform supported by the two-armed levers, a measurement transducer disposed within the base frame and adapted for generating signals substantially proportional to a weight placed on the weighing platform, and a movable load-carrying frame surrounding the base frame, and wherein each two-armed lever is pivoted on the base frame. This concept permits attainment of scales of very low height, hardly sensitive to corner loads, namely loads offset from the center of the scale, and which have a high degree of resolution. The scale may be used for precision weighing, and may have a load region e.g. within a range from about 10 kg to about 100 kg.
