Let's first take a brief look at how the electron scale works. Goods in weighing machine, of the goods under the action of gravity, make the weighing sensor elastomer produces elastic deformation, the paste on the elastomer strain gauge bridge road impedance out of balance, the output electrical signal proportional to the weight value and the internal sensor amplifier, A/D converter, microprocessor and other electronic components processing output digital signals, then through Repeaters to enter data such as weighing display instrument directly show the weight. If the display instrument is connected with computer and printer, the instrument can output the weight signal to computer and other equipment at the same time, forming a complete weighing management system.

In the 1980s before the common loadometer is generally the use of lever principle of pure mechanical structure of the mechanical loadometer, also known as mechanical loadometer. In the mid-1980s, with the growing maturity of high-precision weighing sensor technology, more and more loadometer brands entered the Chinese market; With the development of the loadometer industry, people are more familiar with the loadometer. Mechanical loadometer is gradually high precision, good stability, easy to operate the analog loadometer and digital loadometer to replace.
