している。[Embodiment FIG. 1 is an explanatory diagram showing an embodiment of the present invention. A light emitting section 2 and a light receiving section 3 are arranged in a monitoring oil distribution pipe 1, and the oil to be monitored flows in the monitoring oil distribution pipe. The oil to be monitored flows in from a device (not shown) in which the oil to be monitored is used, and the light exiting the light emitting section 9 and flowing out into the device is absorbed by the oil to be monitored and enters the light receiving section. The light that enters the light receiving section is
The absorbance spectrum is measured by an absorbance measurement device (self-recording spectrophotometer type) 4, and if the measurement result shows a large difference from the reference spectrum of the new oil, a warning is issued to the operator. Figure 2 is a graph showing the absorption spectra of new oil and used oil, and Figure 3 is a graph showing the difference between the absorption spectra of new oil and used oil. In both graphs, the horizontal axis is the wavelength, and the vertical axis is the wavelength. As is clear from the two graphs showing the absorbance, the wavelength range where the difference occurs is 300 to 660 nm.
It is. Table 1 shows an example of the oil pollution determination criteria built into the absorbance measuring device. In this example, a wavelength of 555 nm is used.
