ABSTRACT:
The specification discloses a balance for measuring a load. This balance uses an electronic or optical transducer and a parallelogram support for the load to be weighed. The parallelogram linkage uses one or more torsion bars to resiliently support the load, wherein the deflection of the parallelogram is proportional to the weight of the load. When used with a capacitance transducer, the parallelogram linkage also enables the capacitor plates to remain parallel to one another as the parallelogram is loading, thereby producing a signal that can be electronically processed to provide a liner digital read out signal on indication of weight. Electronic data processing means as provided to calculate and display on indication of weight and/or volume. An optional opitcal indicator means is also disclosed to provide an optical reading of the weight of the load.
