摘要
介绍基于微波相移法的高含水原油含水率传感器的工作原理及其特点。通过试验分析了温度对油水混合物介电常数的影响规律。结果表明:随着温度的升高,呈乳化状态的油水混合物介电常数减小,导致出现含水率测量值低于实际值的现象,严重影响传感器的检测精度。
Both working principle and characteristics of the microwave phase-shift method-based moisture sen- sor which applied to detect the crude oil with high water content were introduced; and the experimental analy-sis of the temperature influence on the dielectric constant of the oil-water mixture was implemented to show that, when the temperature increases, the dielectric constant of emulsified oil-water mixture becomes decreased to result in a phenomena of the measured value of water content lower than the actual value and the sensor' s detection accuracy is seriously influenced.
