摘要
介绍一种电化学阻抗谱在线润滑油含水率传感器,并通过试验测试其性能。结果表明,该传感器可在线准确测定润滑油含水量,监测润滑油中水分含量的变化趋势,防止因冷却器泄漏、密封垫漏水等造成的润滑油中含水量短时间内显著增加而引起的设备重大事故的发生。该传感器可直接安装于润滑油通路中,具有较强的抗电磁干扰性能,在润滑油质量实时监测和机械设备故障诊断中具有广泛应用。
A novel electrochemical impedance spectroscopy（EIS）sensor for on-line measurement of water content in oil was introduced,its properties were tested.The results show that the sensor can be used for detecting the water content in the oil,monitoring water content changed trends,avoiding equipment accidents as the water content in the lubricating oil increased quickly in a short time,such as the cooler leakage,the seat destroying and so on.The sensor can be directly installed in the pathways of the lubricating oil.It has strong anti-electromagnetism performance,is expected to find wide applications in oil quality monitoring and machine fault diagnosis.
