| 摘 要： | 利用油与水介电常数差别较大的特性,借助电容式传感器可测出油品含水率。设计平行板式、圆柱形、圆筒形和螺旋线式4种电容传感器,对润滑油含水率进行检测。对4种传感器检测结果进行比较,分析测量值与理论值之间的差异,阐述影响电容传感器检测精度的因素,比较4种类型传感器的分辨率。结果表明:平行板式与圆柱式电容传感器对水的分辨率相对其他2种传感器效果要好,且在高含水率时,平行板传感器效果更加明显。

| Abstract: | The capacitive sensor can be used to measure the water content in lubricating oil based on the great different of dielectric constant between oil and water.Four kinds of capacitive sensors,the parallel sensor,the columniform sensor,the columnar sensor and the volute shaped sensor were designed to test the water content of lubricating oil.Differences between the measured and theoretic capacitance were analyzed,the factors that influence the measurement precision of capacitive sensors were expatiated,the reso... |
