By comparing the measurements obtained from used and unused oils of the same brand, the SKF OilCheck is able to determine the degree of change in the condition of the oil. Dielectric change is directly related to the degradation and the contamination level of the oil and will allow the user to achieve optimised intervals between oil changes and detect increased mechanical wear and loss of the oils lubricating properties. To facilitate trending the instrument is equipped with a numerical read-out.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003cspan\u003e\u003cb\u003e\u003cbr\u003eNOTE:\u003c\/b\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003eThe SKF OilCheck Monitor is not an analytical instrument.

As a\nconsequence of contamination (by water, metal particles or dirt particles) and\nby electrochemical changes (oxidation) that occur in oils, the dielectric\nconstant of the oil changes. This change in dielectric constant can be used as\nan indication and sometimes a measure of deterioration of oil. The effect of\nthe individual contaminants and electrochemical changes is discussed below.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWater\nand engine coolant:\u003c\/span\u003e\u003cbr\u003e\nThe dielectric constant of a mineral oil is typically 2.1 and the dielectric\nconstant of water is typically around 60, depending on the temperature, which\nis about a factor 30 higher than the oil. This means that contamination of the\noil with water or engine coolant will cause a rapid increase of the dielectric\nconstant of the mixture. Generally a level of 1000 ppm water or higher in oil will\nlead to a significant increase of the dielectric constant.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOil\noxidation:\u003c\/span\u003e\u003cbr\u003e\nOil oxidation, or depletion of antioxidant additives, will lead to a gradual\nincrease of the dielectric constant of the oil.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMetal\nparticles:\u003c\/span\u003e\u003cbr\u003e\nMetal particles are conductive and will lead to a strong increase in the\ndielectric constant. As the metal particles are polar, they will not stay in\nthe oil, but move to the sensor surfaces. This can show as a step-wise (small\njumps) increase of the reading during the measurement.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDust\nparticles:\u003c\/span\u003e\u003cbr\u003e\nDust\nparticles in oil will lead to an increase in the dielectric constant of the\noil. Generally dust levels of ISO 19\/16 or higher will lead to a significant\nincrease of the dielectric constant in oil.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFuel:\u003c\/span\u003e\u003cbr\u003e\nFuel is difficult to detect because the dielectric constant of petrol or diesel\nfuel is very close to the dielectric constant of mineral oil. Fuel\ncontamination does normally cause a slight decrease of the dielectric constant\nand can hence hide other forms of dilution (such as by water).\u003c\/p\u003e\n\u003cp\u003eThe\nincrease of dielectric constant is usually not proportional to the degree of\noil deterioration.
