摘　　要：射频电容法是测量油品含水率的新方法。本文论述了该方法中的射频电容传感器的测量原理，并对传感器敏感探头进行了设计，。实际重油含水率标定测量结果表明该系统的最大非线性误差为±０５％。The radiofrequancy capacitance method is a new method measuring water content in oil.In this paper the principle of radiofrequeancy capacitive sensor in this method is discussed and designing the sensor's sensitive probe.reporrtd.The experiment results in heavy oil show, that the maximum unlinear error of the system is ±0 5%.
