The electronic truck scale is composed of three parts: a truck scale platform (also known as a load carrier), a load cell, and an electronic weighing instrument. The industry generally agrees that the instrument is the brain of the electronic truck scale, which is responsible for the functions of weighing data display, analog-to-digital (A/D) conversion, weighing data processing, and data transmission; the load cell is the heart of the truck scale. In the part, the technical indicators such as power-electricity conversion and measurement accuracy of the truck scale are determined; the weighing platform is the carrier of the truck scale, which is responsible for carrying the measured weight and ensuring that the measurement accuracy of the electronic truck scale will not be affected during the weight transfer process. GB/T 7723 “Fixed Electronic Weighing Apparatus” shows in the error distribution table of typical modules that the error distribution coefficient of the load cell is 0.7, the error distribution coefficient of the weighing indicator is 0.5, and the error distribution coefficient of the connecting parts (including the carrier) The coefficient is 0.5, which is to remind the designers and producers that the carrier is in the whole system of the weighing instrument and has an impact on the measurement accuracy.
