METROLOGICAL CHARACTERISTICS OF MEASURING INSTRUMENTS AND MODERN REQUIREMENTS
Keywords:
Metrological characteristic, accuracy class, error, sensitivity, repeatability, stability, IP rating, electromagnetic compatibility, calibration, metrological traceability, digital measuring instruments.Abstract
This article highlights the metrological characteristics of measuring instruments, their main indicators, as well as the technical and operational requirements imposed on modern measuring devices from a scientific-theoretical perspective. Along with classical metrological parameters such as measurement accuracy, sensitivity, repeatability, reliability, stability, and measurement limits, modern indicators of digital and intelligent measuring instruments—such as IP protection level, electromagnetic compatibility, signal interfaces, calibration interval, metrological traceability, and others are analyzed. The role of metrological characteristics in ensuring the reliability of measurement results is substantiated in the article.
