An Experimental Study on the Light Transmission Characteristics with Oil Contamination
윤활유 오염에 따른 광투과율 변화에 관한 실험적 연구
Abstract
Change in light transmission characteristics caused by various types of oil contaminations was experimentally measured with a built-in type wear monitoring device. Three kinds of iron powders of different size distribution, carbon dust, two kinds of solutions and grease were used for the lest contaminants in this work. Light intensity of the transmitted light was treasured with the contamination level. Results showed that the transmitted light intensity decreased linearly with the contamination concentration in the oil and the slope was affected by the size distribution. Light attenuation was also caused greatly by carbon dust, water contamination and polymeric fibers mainly due to the light absorption. As a result, it was proved that the optical measurement device could be applicable effectively for detecting any significant change iii lubricating oils.
