| 摘 要： | 由于粮堆压力的特殊性,需设计粮库专用压力传感器来检测粮堆重力.利用变极距电容式压力传感器原理设计粮库专用压力传感器,但设计中遇到非线性问题.本文中运用有限元分析方法,设计了应力片模型,有效地改善了电容式压力传感器中的非线性问题.通过在国家直属粮库的实仓测试,该压力传感器性能良好.

| Abstract: | As the particularity of grain pressure,it needs to develop the special grain depot pressure sensor to measure grain-gravity.Using the theory of capacitive pressure sensor to develop the special grain depot pressure sensor,but the non-linear problems encountered in the design.The non-linear problems were solved through the finite element analysis to design the film stress model.Practice test in national grain depot proved that the pressure sensor performance is good. |
