PY - 2012 DA - 2012/06/14 TI - Novel Chromatic Technique Based on Optical Absorbance in Characterizing Mineral Hydraulic Oil Degradation SP - 131956 VL - 2012 AB - A low cost, compact, real-time, and quick measurement optical device based on the absorbance of white light, which comprised of photodiodes in a 3-element color-sensor, feedback diodes, water and temperature sensing element, and so on, was developed and tested in low absorption mineral oil. The device, a deviation from conventional electrical, mechanical, and electrochemical techniques, uses color ratio (CR) and total contamination index (TCI) parameters based on transmitted light intensity in RGB wavelengths for oil condition monitoring. Test results showed that CR corroborated CIE chromaticity ( X - ÿ 坐标），并用不同饱和油降解增加 小号 和色相 H 。CR被认为是独立的油的微粒污染物的，但依赖于化学降解。TCI在油取决于两者的化学降解和颗粒污染物，是最敏感的在蓝色波长范围内至少和在绿色。此外，结果同意这些粘度测定的，总酸值（TAN），和UV-VIS photospectrometry。CR和TCI，得到油降解比键监控参数等TAN的更清楚的指示，并且被认为是有效的标准用于表征液压矿物油的降解。SN - 1687-5915 UR - https://doi.org/10.1155/2012/131956 DO - 10.1155 /一十三万一千九百五十六分之二千〇十二JF - 摩擦学PB进展 - Hindawi出版公司公司KW - ER -
