摘要
目前基于油液介电常数的变化来在线监测润滑油品质和含水率的传感器,存在着需要对传感器输出值进行温度补偿的问题。研究一种具有自动温度补偿功能的在线润滑油水分监测传感器,通过实验考察温度和润滑油中水分含量对传感器的响应灵敏度和动态响应稳定性的影响。实验结果表明,该型传感器无需温度和其他补偿,对润滑油中水分的变化具有较高的线性响应和灵敏度,能准确测量润滑油中的水分含量,且稳定可靠。
At present, the temperature compensation is a need for the output value of the sensor used to monitor the quality and moisture content of the lubricating oil on line based on the change of the dielectric constant of the oil.An on- line lubrication moisture monitoring sensor with the function of automatic temperature compensation was studied.The influ- ence of temperature and moisture content in lubricating oil on the response sensitivity and dynamic response stability of the sensor Was investigated through experiments.The experimental results show that the sensor does not need the temperature and other compensation, which has high linear response and sensitivity to the change of moisture in the lubricating oil, and can accurately measure the moisture content in the lubricating oil, the measurement result is stable and reliable.
