An analogue interface circuit that contains a measuring chain, a transmitter, the input of which is connected to a DC source through an analog demultiplexer, and the outputs of the measuring chain through the analog multiplexer are connected to the measuring amplifier, and a two-channel analog-digital converter with simultaneous sampling is developed. The measuring chain is made in the form of three resistive current dividers, where one divider is formed by a resistive strain gauge and adjusting resistor, and two others — exemplary resistors. This work is aimed at finding possibilities for increasing the accuracy of measurements and interfering analog interfaces for remote measurements using resistive strain gauges by introducing a new structural scheme, which is shown on the Fig.2.

The history of the issue on creation of uniform color spaces is analyzed. It is noted that the calculations based on the results of spectral measurements do not adequately correspond to the human visual perception. For all existing color spaces, it has been proposed to create a uniform metric, a method for determining the length, area and volume in the corresponding spaces, one that corresponds to the human visual perception. The metric is based on MacAdam ellipses, that is, on the threshold perception of the difference in colors. For each point of any color space (two or three measurements) is determined the area of space around each point, within which a person is not able to fix the difference in color. The area is characterized by either an ellipse (two-dimensional case) or an ellipsoid (three-dimensional case). To characterize an ellipse, it is necessary to have three parameters — two axes and the angle of slope. To characterize an ellipsoid, it is necessary to have five parameters — three axes and two angle of slope. The number of sections along a line, along a plane, or in a volume is a measure of length, a plane, or in a volume and sets a metric. The connection of the existing systems for determining color and visual perception of a person is carried out using scales. Scales associate the length, area or volume of any color system with a person’s visual perception. The scale depends on the point of space and the direction in which the movement takes place. As a result, a large number of scales (more than the number of colors, because it is necessary to know the angles of inclination of the ellipses) are needed, which must be agreed by the international community. To use this amount of data and for the corresponding calculations, it is necessary to have an agreed international calculation procedure. It is established, that as a result of the development of computing technology, a large amount of data and a large amount of computation are not a significant obstacle. The obstacle is an insufficient amount of consistent data, that is, it is necessary to perform additional measurements and approvals to determine the areas of space around each point of the color space within which a person is not able to fix the difference in color. A schematic diagram of the measurements and the equipment with the help of which it is possible to carry out the corresponding measurements are proposed. Estimates of the greatest labour intensity of such works are carried out. It is determined what is the most important part of these works is possible to carry out within a few years. For two-dimensional spaces (x, y and u, v), using the results of the classical work of McAdam, we determined the scales for connecting the lengths and areas in these spaces with the visual perception of the human eye. The directions in which the scales are largest or smallest are determined. For these two directions there are given scales that relate the distances and areas of the spa

The paper presents results of the thermographic and numerical analyses of the chosen design of the LED lamp radiator. The LED technology is characterized by the most dynamic development in the ligh ting market. The object of the test is the LED-1 product, which represents the unit module of the multi-module lighting system. Due to high heat fl ux on the small surface of the individual diodes, problems related to the light source cooling become to be one of the basic ones. The parameters of the test modes for the eff ects of changes in temperature are selected taking into account the physical and mechanical properties of the materials used in the manufacture of the product. Tests were conducted in a windless, dark room. Heat was discharged through convection and radiation. The tests in a dark room were conducted. Heat was discharged through convection and radiation. A thermoelectric transducer chromel-copel with dimensions of 400 μm was used to measure the temperature. The temperature was measured by passing a nominal current of 1,67 A through the module. The test results were analyzed and processed. Based on the result it was decided that the works will be continued using the advanced test stand, equipped with the system of the forced air circulation, control and data acquisition system connected with set of the temperature measurers and improved barriers, preventing the interference of the light fl ux with the thermographic measurement. The results of studies of thermal conditions and lighting parameters of the sample of the LED lamp in the process of robots are given. The ability of LED modules to resist the destructive action of heat has been determined. Inspection of potentially unreliable structural elements, strength of fasteners has been done. The luminous effi ciency of LED modules is calculated by indirect and direct, thermal and optical measurements. For the clarity of the working picture was a measured base spectral characteristic. The case temperature, with basic measurements, was 45 °C, and the ambient temperature was 24,2 °C. Analyzing the measurement results — the deviation of the light characteristics amounted to < 10 %. Bringing measurement results to model drawings in CAD SolidWorks allowed us to create a consistent computer model of the product. The model allows with sufficient accuracy to carry out all the calculations for thermal and mass-dimensional data.

The article proposed and justified the need for on-line calibration, the essence of which is to conduct individual calibration in real time directly at the place of operation of gas meters, taking into account the conditions and influential factors for which they conduct measurements to determine the actual calibration characteristics. This procedure should be one of the primary tools in ensuring widespread adoption of Metrology 4.0. It was noted that the key direction of development of the metrology industry should be the conformity assessment of the gas control and metering system. The given example of calculations (Table 1) carried out in assessing the compliance of such a system. It was found that the greatest weight has the error of the gas meter. In order to carry out the on-line calibration procedure, it is proposed to use the installation with parallel installed reference meters (Fig. 1), which is designed as a mobile stand with the ability to be transported to the work site. The necessity of on-line calibration is justified on the example of the obtained characteristics of gas meters (Fig. 2, Fig. 3). The results of the gas meter calibration on the working environment natural gas (Fig. 4) are presented and the total uncertainty of the gas metering system is calculated (Table 2). The application of the on-line calibration procedure leads to the need to develop the concept of introducing intelligent or smart metering of natural gas using intelligent information-measuring systems. As part of the implementation of smart metering, the possible introduction of two-tariff metering of natural gas. As a tool for statistical processing of the data, it has been proposed to apply control charts that have been tested for reference standards and are recommended in international documents.

The article describes a variant of constructing an instantaneous flowmeter, designed to monitor the energy characteristics of internal combustion engines located on long-term bench tests, under different load conditions. The result of the development is a system using the method of indirect control of the weight of consumed fuel from a sample tank, by measuring the pressure in it. To ensure the required accuracy and stability, the flowmeter uses a pressure-period frequency converter built on a bi-generator circuit. As a result of the research carried out in the work: the algorithm of work and the functional scheme of the automated device intended for precision control of instantaneous fuel consumption are developed; the method of calculation of the basic metrological parameters of the flowmeter of instantaneous values is proposed; conducted research is the basis for designing new automated devices for precision consumption control.

The work is devoted to the research of the electrical parameters of the domestic telephone cables in the frequency range from 1 to 30 MHz. The paper presents the results of the experimental determination of the frequency characteristics of the transmission parameters and the crosstalk of the TPPep 10х2х0,4 and TPPepZ 10х2х0,4 types telephone cables produced by ODESKABEL PJSC. The conformity of the domestic production cables with the requirements for digital subscriber line cables for VDSL2 technology services is determined. According to the results of the measurements, approximation formulas for the frequency dependence of the own attenuation, near end crosstalk and equal level far end crosstalk, which are proposed to be used in the modelling of the transmission systems using VDSL2 technology on the domestic broadband access networks based on these cables, are determined.

The most important parameters of technically complex objects are controlled by means of measuring channels, which in turn are calibrated in established terms. These procedures are sometimes economically unattractive and gradually, along with the classic calibration, online monitoring of channels is being introduced. It is promising to use online monitoring methods for solving inverse measurement problems that allow to obtain a slightly distorted input signal. Nowadays there are no normative documents regarding the inverse problems and the quality of the input signal restoration. The scientific basis must be created for their implementation. Some scientific theses that should be used when creating normative documents, terminology and recommendations are considered in the article.
