【摘要】 主要对石油原油的含水率测量分析进行了原理建模,并利用等位第三电极对测量电容电场矫正作用,设计了用于典型油品含水率测量的射频导纳电容传感器。该方法为间接测量法,通过测量传感器的电容导纳随油品的介电常数变化来反映油品的介质组分含量,进而对油品的水分及其它杂质含量进行高精度测量,实现了对油品质量的检测与评价。更多还原

【Abstract】 In the paper, we mainly designed a model for the ratio measurement of water content in crude oil, adopting the correcting affect of the third electrode with equal electric potential on electric field of capacitance; we designed a radio frequency admittance capacitance sensor for ratio measurement of of water content in crude oil. This is an indirect measurement method, by measuring the admittance variations of capacitance sensor with the dielectric constant of oil, we can get the medium composition content of oil, and then we can measure the water content and other impurity content in the crude oil with high precision, and realize the goal of detection and evaluation of oil quality.更多还原
