The influence of the inadequacy of the a priori knowledge about the properties of measurement results and standards used in the formation of estimates of the probabilistic characteristics of errors is considered. The mathematical support of the procedure for determining the dependence of reliability on the inadequacy of the form of the probability distribution of the estimated estimate, excluding the residual systematic error of the measurement results and the value reproduced by the standard, as well as the volume of the sample used, is presented

The authors propose a position-binary technology for processing signals of the load due to the weight of the rod string on the suspension of the sucker rod pumping unit. The method is applicable for identifying the technical condition of sucker rod pumping units. An algorithm for identifying the technical condition of such units is developed. The implementation of the developed algorithm on a real-life object using a remote system confirmed the increased reliability of automated diagnostics.

The organizational and methodological principles of the functioning and development of the shared use equipment center of high-precision measurement technologies in the field of photonics in the interests of ensuring equal access of scientists and researchers to expensive research and measurement complexes, scientific equipment and facilities are presented. The methodology of the target supplementary equipping of the shared use equipment center is considered using the example of creating a measuring and calibration complex for metrological support of research methods and technical means of microwavephotonics (MWP)

In this paper, we consider a circuit-based solution for a flow-through measurement of the average radiation power of fiber lasers at levels up to 3-4 kW and a density of up to several 3 kW/cm². The meter does not require the use of complex water treatment systems and the use in the meter of means of absolute flow and water temperature measurements at the inlet and outlet of the meter, as well as the parameters of the electric current and voltage when it is electrically calibrated.

The feasibility of assessing the validity of calibration results in the development of new methods of calibration and comparison with existing methods substantiates. The reliability of calibration of infrared thermometers TESTO 830 and Sight when you used different standards of precision was evaluated. The results obtained by simulation (Monte Carlo). Selection of test points in the measurement range of the infrared thermometers discussed. The study was conducted on the basis of materials of calibration in FBU «Novosibirskiy CSM». The proposed methodology can be used in the analysis of existing and development of new methods of calibration of measuring instruments.

The capacitive sensor for high-voltage pulses amplitude and time parameters measurements in the range 5 to 300 kV is developed. The sensor rise time is 1,5 ns, time constant is 170 μs. The 2,9 % standard uncertainty of measurements by sensor is obtained in result of calibration.
