“…Три источника инфракрасного излучения (с максимумами испускания на длинах волн 1,7, 1,9 и 2,2 мкм) располагаются напротив фотопри-емного модуля. После включения источников и фотоприемника определятся величина мощности излучения доходящего от источников до фотоприемника (по каждому из трех источников отдельно), данные сопоставляются с калибровочной кривой [4,5].…”

“…Для повышения точности измерения следует использовать единую калибровочную кривую, которая определяется как зависимость изменения разницы нормированных сигналов, получаемых от светодиодов LED 17 и LED 19, относительно нормированного сигнала, получаемого от светодиода LED 22, и может быть представлена следующей формулой [4]:…”

The main object of the work was developed the device based on GaInAsSb diodes for measurement water content in oil. Optical absorption method was used in this device. Three LEDs emitting in the range from 1.6 to 2.4 μm, and one wide-band GaSb/GaInAsSb/GaAlAsSb photodiode were used as sources of radiation and detectors.The device was developed on the basis of selective optical absorption method of detection for measuring water content in oil. As sources of radiation, LEDs emitting in the range from 1.6 to 2.4 μm were used. The results of the experiments showed that the method used makes it possible to measure the water concentration in oil in the range from 0.2 to 40% with an relative error of not more than 2 %.The technical requirements and operating parameters of the used light and photodiodes were established. Investigations of the dependence of the luminescence spectra of LEDs on temperature have shown the importance of using thermal control on the sources and detectors of radiation. The possibility of using one device for different types of oil, as well as oil products during preliminary calibration were shown in the paper. The importance of using a rotary pump for mixing and pumping the analyzed medium and a flow cell was established.
