    摘要：本文介绍一种电化学阻抗谱(Electrochemical impedance spectroscopy,EIS)在线监测机油含水率传感器。通过对其大量试验结果的分析,论述用于在线监测机油含水率变化,以便对柴油机的安全运用起保护作用的可行性。

    Abstract：A novel Electrochemical impedance spectroscopy(EIS) sensor for on-line measurement of water content in oil has been reported.It is found that the sensor,which is installed in the oil loop of the lubrication system,can detect low level water content in oil.Due to the advantages of small size and easy installation,this sensor is expected to have wide applications in oil quality monitoring and machine fault diagnosis.
