The development of China's electronic weighing apparatus industry has experienced a tortuous process. From the initial reliance on imported high-end ICs of more than 70 yuan to the wide application of bipolar and triple-integral circuits, the entire industry has entered a Spring and Autumn and Warring States era, and various large and small manufacturers have flocked, some of which have technical strength and forward-looking vision. The major manufacturers stand out from them, promote the penetration of the weighbridge into the mechanical weighing market, and open up new application fields. The market's requirements for improving the quality of weighbridges and the cost pressure brought about by increasingly fierce competition urgently require the birth of "China Core" for weighing instruments.


On December 14, 2007, under the guidance of the Electronic Information Product Management Department of the Ministry of Information Industry, the 2007 "China Chip" Technology and Development Conference and the 2nd "China Chip" sponsored by the Software and Integrated Circuit Promotion Center (CSIP) of the Ministry of Information Industry The awards ceremony was grandly held in Beijing. The high-precision Sigma-Delta ADC chip CS1242 launched by Shenzhen Chipsea Technology Co., Ltd. won the "China Chip" Most Potential Award in 2007. Among the 10 IC products awarded by "China Chip", the only one used for measurement and industrial control The IC in the field has a resolution of 24bit and an effective precision of up to 21bit. CS1242 won this honor, which means that electronic weighing instrument manufacturers also have a "Chinese core" that can compete with the high-end products of foreign top IC design companies. From then on, they can get rid of the dependence on high-priced imported ICs, as well as bipolar and triple integral technologies. The troubles in the quality of the whole machine are brought about, and the technical level and international competitiveness of the products are improved.
