Abstract:
1. An apparatus for measuring oil oxidation, comprising: a light-emitting means; a plurality of first light-transmitting means, which extend from the light-emitting means, for introducing light into oil at a plurality of different incident points; a plurality of light-reflecting means, which are immersed in the oil and disposed opposite the incident points, wherein each of the light-reflecting means is located at a different distance from the incident points; a plurality of second light-transmitting means, which extend from the incident points; a plurality of light-receiving means, which are connected to the second light-transmitting means, for receiving the light and generating signal outputs corresponding to the received light; and a control portion, which calculates a fluorescence quantum yield and a light absorption coefficient of the oil, based upon the signals from the light-receiving means, and compares the calculated fluorescence quantum yield and light absorption coefficient with reference fluorescence quantum yields and light absorption coefficients pre-stored in the control portion to determine the oil oxidation.
