Zdeb V. The improvement of metrological characteristics of multichannel industrial measuring instruments on the place of operation

Thesis deals with the problem of improving the metrological characteristics of multichannel measurement tools at the operation site. Analytical review of existing procedures and methods of construction of modern digital multi-meters for work with industrial primary measuring transducers and their calibration capabilities was carried out at an operation site. The analysis showed that the principal disadvantage of the known methods and tools for building reinforced concrete constructions is the practical lack of opportunities of calibration at an operation site, taking into account the influence of the remaining parameters of the lines of communication between sensors and a secondary device. This will provide a specified metrological reliability of measuring instruments, conduct operative control of the flow of measuring processes and enable metrological verification procedure of measuring devices directly at an operation site. The structure of multi-parameter digital meter of industrial measuring converters using code-driven measures was established and improved to enhance their metrological reliability. - algorithms and means of implementation of operational metrological control of multi-parameter digital meter of industrial measuring converters with galvanic separation measuring channels at an operation site were developed
