摘要

method of measuring calibration rings, using tensometryczny measurement deformation, characterised by the fact that the ring gauge, equipped with strain gauges on its internal peripheral surface is positioned symmetrically inside the external ring situated pom iu0119dzy slab lower and upperand between the ring and the ring outer measuring placed torus with flexible material, then fill the torus air until chamber filling space between rings and plates and to obtain a constant volume, which is compared in artou015bu0107 pressure manometer digital odksztau0142calnou015bciu0105 ring measurementregistered by the bridge tensometryczny in the common function of time, and provides a linear deformation - stress, then compared the functions of function theoretical deformation - stress and determined coefficient and constant calibration.the outer surface of the ring gauge, and inner surface of the outer ring torus on synthetic oil.system for measuring calibration rings is characterized by the fact that the ring gauge (1), equipped with strain gauges (2) on its inner peripheral surface is connected with the bridge tensometrycznym (3), connected to the data recording system (4), whereby the ring pomiaro you (1) is placed symmetrically inside the external ring (5), situated between the bottom plate (6),and the top plate. between the measuring ring (1) and outer ring (5) is the torus (8) of the flexible material, while the outer ring (5) is about 0.5 - 1.0 cm above the ring gauge (1), and the torus (8) is connected by a digital pressure gauge (9) with compressor (10).the lower plate (6) and the upper plate are joined together permanently by screws and are made of a material hard to deformable. outer ring (5) is permanently attached to the bottom plate (6).
