MEASURING METHOD FOR DEGREE OF DEGRADATION OF LUBRICATING OIL, AND MEASURING DEVICE THEREFOR, AS WELL AS LUBRICATING OIL MONITORING SYSTEM IN MACHINE AND DEVICE |
摘要 |
Provided are a method of measuring a degree of degradation of a lubricating oil and a measuring device therefor, in which (a) acidity is measured through use of an ISFET of hydrogen ion sensitive type and (b) dielectric constants or electrostatic capacitances at two or more different frequencies are obtained, to thereby determine a degradation state of the lubricating oil based on the acidity and a plurality of values of the dielectric constants or the electrostatic capacitances. Accordingly, the degree of degradation of the lubricating oil can be measured easily and precisely and a degradation mechanism of the lubricating oil can be predicted. |
