The earliest weighing system designs were based on the work of Leonardo Da Vinci and Archimedes. They used the positioning of calibrated counterweights on a mechanical lever to balance and thereby determine the size of unknown weights.
A variation of this device used multiple levers, each of a different length and balanced with a single standard weight. In weighing technology, the first major design was represented by the introduction of electronic load cells. At present most applications prefers electronic load cells.
Load cell forms the central body of every modern electronic weighing system. The load cell should transform a mechanical deformation into an electronic signal which has to be proportional to the value of the mechanical deformation by the load cell.
If a load is used into the center line of a cylindrical load cell, it will create tension or compression. If load is used to a beam, it will create shear or bending. Beams should be installed in their double or single ended configurations. Factors are making the decision between structural and stabilization requirements.
