Problems solved by technology

At present, the resistance and voltage measurement of strain gauges are completely dependent on manual testing. Due to the large output of strain gauges, many workers are required, resulting in high labor intensity, high production costs, low test efficiency, and error-prone, which is not conducive to the stability of product quality. sex control
