Kraiovskyi V. Development of the thermometry physical basis with the use of new sensitive elements of thermal converters

The thesis provides the justification and a new solution of an important scientific and technical problem of the development of the thermometry physical basis by introducing new sensitive elements of the temperature measurement means and the methods of their characteristics simulation, obtained on the basis of the latest thermometric materials with improved metrological and operational characteristics. The concept of simulation and obtaining of thermally stable sensitive elements of temperature measuring devices based on the latest thermometric materials obtained by alloying of semi-Heuser phases by developing an method for iterative simulation of structural, energy, thermodynamic and kinetic characteristics of thermal converters sensitive elements taking into account the results of experimental measurements. A method is developed for simulation of the kinetic characteristics of thermal converters new sensitive elements in a wide temperature range. The regularities of the transformation functions of sensitive elements of temperature measuring devices based on the latest thermometric materials in the temperature range of 4.2÷1300 K with improved metrological characteristics were established. A method of obtaining a thermoelectric pair of a thermoelectric thermometer sensitive element is proposed, both branches of which are made of the latest thermometric materials of electron and hole types of conductivity, which in 4÷6 increases the sensitivity of the existing thermocouples. The received thermally stable sensitive elements of electrostatic thermometers from the latest thermometric materials is proposed, which significantly increases the accuracy and expands the range of temperature measurements.
