    In the middle of the 20th century, a simple electronic weighing instrument appeared, which made the weighing instrument enter the electronic age. The combination of microprocessors and load cells has brought about a revolution in the field of weighing. Since then, microprocessors have become more and more widely used in weighing, especially in dynamic weighing, and have basically replaced the original complex computing system. The continuous development of microelectronics technology and the emergence of large-scale and ultra-large-scale integrated circuits have enabled functions such as weighing and process control to be combined into the same electronic unit.

    In the 1980s, electronic weighing instruments spread to various fields from micro weighing to large professional weighing. The weighing instrument products have developed to thousands of specifications and varieties. The static accuracy is generally above 0.1%, and the dynamic accuracy is generally 1%. ~0.2%.

    At present, weighing instruments on the market can be divided into three categories: mechanical scales, electronic scales, and electromechanical combined scales according to their structural principles. Among them, mechanical scales are further divided into lever scales (including equal arm lever scales, which are also narrowly defined balances, unequal arm lever scales) and spring scales. Weighing instruments can also be divided into non-automatic weighing instruments and automatic weighing instruments according to the measurement method.
