英文摘要：

The pressure signal measurement and the maximum pressure display system of screw press were studied, and various measurements were included in the hardware design to solve problems of small signal extraction, interference, high gain signal stability, rapid acquisition of transient signal and maintaining the peak. The circuit designed provides a reference value for general small signal processing, peak acquisition and display.
