It is shown that traditional methods of metrological provision for critical sensors do not provide the required level of confidence
for measurement results and economic efficiency. The desirability of changing to automatic monitoring of the metrological
precision of sensors during operation is substantiated and requirements for the metrological procedures that are necessary
are determined.

A method of improving the metrological characteristics of monitoring instruments, based on the use of a system of coupled
oscillations as a highly sensitive recorder of the state of balance of a measuring circuit and simultaneously as a converter
of the measured and compensating quantities in the information signal is considered. It is shown that it is possible to improve
the metrological characteristics by constructing an intelligent measuring mechanism using a system of active interacting components.

The paper discusses providing measurement and monitoring accuracy for pressures in the gas systems of boiler plant. It is
shown that the errors in measuring and monitoring pressures on the basis of existing metrological support to boiler plants
may exceed the limits laid down for the permissible pressure deviations at the inlet to the gas burners by large factors.

The principles of system analysis of measurement problems encountered in the preparation and execution of tests of complex engineering objects are formulated. A general model of metrological testing support is proposed that is a model of a measurement control system that takes into account the effect of measurement accuracy on the test results and the propagated errors of measuring and test equipment.Translated from Izmeritel'naya Tekhnika, No. 3, pp. 21–23, March, 1995. 相似文献

The features of the metrological backup of broadband radar measuring systems are considered. The list of their metrological characteristics includes the metrological characteristics of the narrow-band radar measuring system and the errors in measuring broadband characteristics. It is established, by comparing the frequency and time characteristics of the scattering, that it is necessary to estimate the overall error of measurements of the effective scattering cross section in the frequency domain, while in the time domain it is only necessary to describe the random errors of measurements of the smoothed pulse characteristics of the targets. 相似文献

Designing a computerized metrological support system is considered, which incorporates not only metrological considerations
on measuring instruments but also the computerized choice of production preparation facilities. Representations are considered
for information on measuring instruments that allow one to integrate the metrological system in a unified CALS system for
the organization.

Novel active techniques are surveyed for measuring the temperatures of solids. They are based on using an optical beam, usually from a laser. Laser thermometry methods are compared with contact and radiation ones. Problems are discussed in relation to the general use of the new methods in engineering monitoring. The main problem is the lack of metrological support. 相似文献

Methods are considered for measuring the parameters of nanoparticles in natural and technological media as used in the nanoindustry.
Exact monitoring is required for the parameters of the medium where the nanoparticles are suspended in order to obtain reliable
measurement data. Measurement methods are examined for the nanoparticle size range 5–100 nm for aqueous and gaseous media
in order to set up a metrological suite for measuring the parameters of nanoparticles in these media.
