文章从电容–液位的测量原理、机械结构的构造机制和湿度–温度–介质变化的补偿修正等方面对精密套筒式多段电容液位传感器的开发进行了深入探讨,通过机械结构造型设计、电子测量电路设计和嵌入式应用软件设计逐步完成了简易实用、高精度、温度–湿度–介质自适应、大测量范围的套筒式多段电容液位传感器的研制。<br/>The paper deeply discusses the design theory of the multistage-cylinder-capacitor-sensor for liq-uid-position from relation of capacity and liquid-position, mechanism of mechanical manufacturing and compensation for change of temperate-humidity-medium. It expounds the sensor design about mechanical structure, electronic measuring circuit and embedded software. It runs up to simple and practical, high-precision, self-adaption for temperate-humidity-medium and large mea- suring range.
