Developing of high accuracy and low capacity strain gage based load cell for electronic scale

A strain gage based load cell optimized with final element analysis design. Besides some advanced stabilizing technologies like temperature impact, static overload, computer pattern recognition (CRT) technology is also used to make dynamic simulate and analysis. The multivibration stress release method base on that is creatively used in the production of this load cell. With all this technologies, high accuracy, high stability is achieved on the load cell with the capacity of 30 g. With this load cells, strain gage based electronic balance with divisions of 300,000 and resolution of less than 0.2 mg is practicable. The capacity and accuracy of this load cell is much higher than similar product on the market while its price is much lower than electromagnetic load cell. Therefore, the commercial prospect of this load cell is encouraging.
