Dominyuk T. Influence of technological and operational factors on the thermoelectric inhomogeneity and metrological properties of thermometers

The dissertation is devoted to problems of measuring temperature thermoelectric sensors, in particular the influence of thermoelectric inhomogeneity and temperature measurement accuracy. In this thesis we used the method of acoustic emission as the research method of thermoelectric inhomogeneity, which allows greatly improve the reliability of measurement results. It is shown that the change in thermoelectric inhomogeneity is accompanied by acoustic emission. Set a level of maximum degree of chromel deformation, after which structural recrystallization is a practically eliminated. Proposed and approbated a method of highlighting discrete acts of low-level (low energy) acoustic emission.
