FIELD: instrument engineering. ^ SUBSTANCE: in invention, parameter "total impurity" is defined by change of running oil optical density with regard to fresh oil against three spectral ranges by polychromatic optical radiation transmission through oil and recording of transmitted through oil radiation intensity in three spectral ranges - red, green and blue. In addition, diagnostic parameter "chemical destruction" of oil is used to monitor oil performance. Instrument includes optical source, flow-through cell, optical radiation receiver and signal processing unit. Besides, source contains polychromatic radiation source and receiver includes photo sensor, which records optical radiation intensity simultaneously in three spectral ranges. ^ EFFECT: invention improves self-descriptiveness and reliability of on-line oil performance monitoring. ^ 6 cl, 8 dwg |
