The detector estimates oil deterioration based on the information about chemical degradation, total contamination, water content of oil and oil temperature. The oil oxidation is estimated by “chromatic ratio”, total contamination is measured by the changes in optical intensity of oil in three optical wavebands (“Red”, “Green” and “Blue”) and water content is evaluated as Relative Saturation of oil by water. The detector is able to monitor oils with low light absorption (hydraulic, transformer, turbine, compressor and etc. oils as well as oils with rather high light absorption in visible waveband (diesel and etc. oils). In a case study that the detector is applied to a diesel engine oil, it is found that the detector provides good results on oil chemical degradation as well as soot concentration Korean 한국트라이볼로지학회 기계 상태진단을 위한 인-라인형 오일 모니터링 스마트 센서 In-line Smart Oil Sensor for Machine Condition Monitoring Article 2 한국트라이볼로지학회지, v.24, no.3, pp.111 - 121 한국트라이볼로지학회지 24 3 111 121 kci ART001377996 smart sensor oil deterioration machine condition monitoring diesel engine oil
