development of an optoelectronic device for monitoring technological parameters of drinking water the new improved construction of optoelectronic multiparametric colorimeter is presented. it features the cylinder-shaped cell (two semicylinders sticked together) with central hole, which is fixed during the technological process of semitransparent liquid pumping; n+1 optocouplers being available permit the control of n-components presence and content in the liquid composition. keywords: laser diode, photodetector, optocoupler, quartz cell, semitransparent liquid, summator, photoelectric signal processing unit, measuring instrument to ensure the efficiency of the proposed devices [1-3], it is necessary to have experimental characteristics of the main elements of colorimeters, one of which is the pass-through characteristic of an optocoupler pair with an open optical channel (ook). to compare the results of calculating the transmission coefficient of the optical signal (os) with the experimental value, a characteristic of the optocoupler pair without ook is necessary. the characteristics of the optocoupler pairs …

green, red, infrared. as a result of the experiments, it was decided to use the following leds as optical radiation sources: blue “piranhas” led470 – p8l5 – a80, green “piranhas” led515 – p8l5 – a80, red “piranhas” led625 – p8l5 – a80, infrared “piranhas” hir36. fig. 1. scheme for taking characteristics of an optocoupler pair most of the currently used instruments use a differential method of measuring light absorption, and it is necessary to have exemplary means, which can be color glass filters or selected liquids with the equivalent spectral characteristics. the ratio of the optical density of the product being monitored to the optical density of the reference product is measured using an optical system with electrical compensation. in proportion to the change in the ratio of optical densities, the output voltage supplied to the recording device changes [4]. fig. 2. the characteristics of the optocoupler pair in most …

l lens, inside which a cavity is made in the form of a cylinder, and a cylindrical or prism silver reflector can be installed in the center of the cylinder surface, for example a tetrahedral rod with reflective surfaces. the complexity of manufacturing a ball lens, especially the polished surface of the central hole, is a significant drawback of the colorimeter. the development of an optoelectronic device considered in this article for monitoring the technological parameters of drinking water is much simpler to fabricate, since a quartz cuvette consists of two semi-cylindrical tubes 15, between which a flat mirror with two-sided reflection 8 is glued (fig. 1, a, b). a graduated glass funnel 18 is attached to the cuvette, where a controlled fluid is poured 9. the cavity can be closed by a valve 19 from the bottom. the whole structure is placed in the housing 18 (fig. 1a), and …

rm a reference optocoupler, which is provided in order to compare the measuring signals with the signal of the reference channel and to ensure the reliability of the measurement results. when filling the cylindrical hole of the cell 15 with a controlled liquid 9, it is irradiated with laser diodes. in the first position of the switch, the radiation flux of the laser diode 4 is focused, passes through the controlled liquid 9, is reflected from one of the two surfaces of the flat mirror 8, and again passes through the controlled sample 9, then it passes to the measuring photodetector 11. then the signals go to the photoelectric signal processing unit (bofs) - 16, where the ratio of the signals of this measuring stream and the compensation signal from the diode 3 and the measuring photodetector 10 is realized. in the second position of switch 2, the second optocoupler …
