Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Analysis of Metrological Characteristics of Coating Thickness Measuring Instruments O.A. GAVRILOVA, V.S. SEKATSKY The analysis of the technical documentation of coating thicknesses showed that there is no systemic and complete representation of metrological characteristics. This does not allow the consumer to fully judge the accurate and operational indicators of thickness gauges. A structured minimum required set of regulated metrological characteristics of magnetic thicknesses of coatings is proposed, which must be indicated in the technical documentation. It is proposed to normalize parameters limiting the field of application of the device with its permissible error and electromagnetic characteristics. Keywords: measuring instruments, coating thickness, metrological characteristics, analysis. DOI: 10.25791/pribor.4.2021.1250 Pp. 01-06.
