Development of micro scale lubricantdeterioration sensing system with high sensitivity using an arrayed waveguide grating in visible region

我们在实验室用旋转压力容器氧化试验（RPVOT）装置制备了被氧化的样品油。我们使用比色膜片分析仪测量了由样品油产生的膜片的颜色。研究了颜色与FT-IR分析的关系。因此，发现了在第一阶段检测氧化产物的可能性，这成为主动维护的关键点。此外，作为片式传感器件发展的前一阶段，对能够在润滑油中直接监测的光学传感器件进行了试制并进行了评价。结果表明，所设计的颜色参数对实际机械齿轮油的润滑诊断是有效的。

We prepared sample oils which were oxidized in the laboratory using a rotary pressure vessel oxidation test (RPVOT) apparatus. We measured the color of membrane patches produced from sample oils using the colorimetric patch analyzer. The relationship between the color and the FT-IR analysis were investigated. As a result, the possibility of the detection of the oxidation product in the first stage that became the key point of a proactive maintenance was found. Furthermore, as the former stage of the chip type sensing device development, the optical sensing device that is able to be directly monitored in the lubricant was made for trial purposes and it was evaluated. It was found that the color parameter designed in this present study is effective to a lubrication diagnosis for the real machine gear oil.
