摘要
采用双电容器的结构设计了一种新型双电容式料位传感器。传感器结构简单,安装灵活,可工作在恶劣的环境中,可减小因温度和湿度造成的测量误差,可减小分布电容和寄生电容对测量结果的影响,不仅适用于金属容器,也适用于非金属容器的料位测量。
A new type of double capacitive material level sensor which adopts a structure of double-capacitor is designed.It is simple in structure,easy to be installed.This kind of sensor can work in adverse circumstances,and reduce the measure error caused by temperature and moisture,and reduce the influence of distribute capacitance and parasitism capacitance on measure result.This sensor can be used for metal container,as well as nonmetal container.
