FIELD: physics; measurement. ^ SUBSTANCE: invention relates to measuring techniques. Control of oil decomposition is done based on varying the test parametre of working oil relative that of clean oil. The test parametre is calculated using fluorescence intensity of oil, simultaneously measured in three spectral ranges and two operating spectral ranges are used, in which intensity values are greater than in the third. The device has a case in which there is an optical window, and a receiving-transmitting unit, in which are fitted an optical emitter and receiver with a measuring photodetector. The measuring photodetector is a colour sensor, which allows for simultaneous measurement of fluorescence intensity of oil in three spectral ranges. ^ EFFECT: increased sensitivity and reliability of control. ^ 5 cl, 6 dwg |
