The development of China's electronic weighing apparatus industry has experienced a tortuous process. From the initial dependence on imported high-end ICs with more than 70 yuan each to the wide application of bipolar and triple integral circuits, the whole industry entered the spring and Autumn period and the Warring States period. All kinds of manufacturers, large and small, swarmed, and some large manufacturers with technical strength and forward-looking vision stood out, which promoted the penetration of weighbridge into the mechanical weighing instrument market and opened up new application fields. However, the requirements of the market for the improvement of the weighbridge quality and the cost pressure brought by the increasingly fierce competition urgently require the birth of the weighing instrument "China core".
