  • Method and device for determining the state of degradation of a lubricant oil
    Patent number: 9063075
    Abstract: The present invention provides a method and a device for determining the degradation of a used oil. The method of the invention is based on calculating the components in the red, green and blue transmission spectral bands IRO, IGo and IBo of the unused oil, carrying out a number of measurements of the transmittance of the same oil after use, calculating the colour indices of the used oil and the reference colour index as CI=1×IR+0.5×IG+0.5IBCIREF=1×IRO0.5×IGO+0.5IBO and obtaining the overall degradation value as OD(%)=100?100×log10(CIREF/CI). By virtue of the method and the corresponding device, real-time monitoring of oil degradation is facilitated.

  • Method and Device For Determining the State of Degradation of a Lubricant Oil
    Publication number: 20140146307
    Abstract: The present invention provides a method and a device for determining the degradation of a used oil. The method of the invention is based on calculating the components in the red, green and blue transmission spectral bands IR0, IG0 and IB0 of the unused oil, carrying out a number of measurements of the transmittance of the same oil after use, calculating the colour indices of the used oil and the reference colour index as CI=1×IR+0.5×I0+0.5IBCIREF=1×IR00.5×IG0+0.5IB0 and obtaining the overall degradation value as OD(%)=100?100×log10 (CIREF/CI). By virtue of the method and the corresponding device, real-time monitoring of oil degradation is facilitated.
