摘要：

针对目前润滑油含水率检测技术仪器设备昂贵、在线测量技术较少的不足，基于微波谐振技术设计了一种在线检测装置。该装置由微控制器单元、谐振腔、同轴传输线、压控振荡器、对数检波器、PC机组成。结合有限元仿真软件HFSS，设计了微波谐振腔，并仿真水油均匀及不均匀分布状态下的S参数响应曲线，得到谐振频率与含水率的关系。试验搭建检测装置，在含水率为0~1.2%时，测得谐振频率与含水率的关系，试验结果与仿真结果相符。在16~30 ℃内进行温度补偿，提高了检测精度。最后，将检测装置接入油液管路中进行在线测量，结果证明了检测装置的有效性。

Abstract:

In view of the shortcomings of the current lubricating oil water content detection technology with expensive equipment and few online measurements， an online measurement device based on microwave resonance technology was designed. It consists of resonator， microcontroller unit， coaxial transmission line， voltage-controlled oscillator， logarithmic detector and PC. Combined with the finite element simulation software HFSS， a microwave resonator was designed， and the S-parameter response curve was simulated under the state of uniform and non-uniform distribution of water and oil， and the relationship between resonant frequency and water content was obtained. In the experiment， the measurement device was fabricated to measure the relationship between resonance frequency and water content in the range of 0~1.2%， and the results are consistent with the simulation. Temperature compensation was carried out within 16~30 ℃ to improve the measurement accuracy. Finally， the device was connected to the oil pipe for on-line measurement， and the results prove the effectiveness of the measurement device.

Key words: electromagnetic measurement, lubricating oil, microwave resonance, water content, water-oil distribution
