Yatsyshyn S. Development of Theory Principles and the Consideration of Error Minimization Methods and Algorithms for Thermoeletric Thermotransducers based on Statistic Thermodynamics

Dissertation is devoted to development and use of thermoelectric thermotransducer with enhanceable exactness and metrology reliability. The mechanisms of transformation function instability are considered, investigating their changes at typical external environments; possibilities of the use of thermodynamic presentation is analyzing concerning thermometric substance, as the thermodynamic selected system. The effective methods of action are studied on transformation function. Expression is shown out for the total influence function, as a maximum value of relative instrumental error. The last is presented as combination of three pairs of dimensionless influence functions. The experimental researches are conducted: to the spectrum of thermoelectric properties, electric resistance, microhardness and other structural characteristics. The methods of thermotransducer construction are realized improving the metrological operating characteristics. The algorithms of thermotransducer instrumental errors minimization are developed.
