UNCERTAINTY ESTIMATION OF THE STRAIN GAUGES CONFIGURATION
(pp. 46-51)

Abstract. The trend of improving the quality of products in the field of energy is aimed, in particular, at improving the quality of validation and verification of the declared parameters (strength of industry and research nuclear reactors and other pressure vessels, etc.). For verification of the parameters of the integrity and strength within the plant and operational tests and control the operating parameters using high-quality measurement and control equipment, which is part of the measuring channel. Improving the quality of the information is obtained, in particular, during full-scale tests using strain gauges, leads to an increase in the quality of products in general. The measurement result depends on many factors, which are not always possible to control due to technical and economic reasons. Using the apparatus of mathematical analysis and the theory of elasticity, it is shown that one of the parameters – the configuration of the strain gauge can reduce the uncertainty of the results of measurements by tensometric methods.

Keywords: uncertainty, accuracy, strain gauge, tensometry, field tests, data processing.
