Abstract
In this chapter, the heat flux distortions in the sample are considered and possible methodical errors in the thermal conductivity and thermal resistance measuring process are evaluated. It is shown that using the results of analytical studies in designing a measuring system implementing a stationary hot plate method we can choose such basic thermophysical and geometric factors combinations of primary heat flux sensors taking into account the characteristics of samples that enable methodical errors to minimum. Temperature and thermal fields distortions study due to the heat flux sensors design features shown that it is necessary to minimize the difference between the thermal conductivity values of sensor sensitive and guard zones. A proper thermoelectric pair for such sensors is a constantan-nickel couple that provides temperature and time stability of characteristics simultaneously. A technique for designing precision sensors has been developed. An analytical study results implementation ensures the optimization sensors design and allows to use them in modern thermal conductivity measurement systems for non-standard, dimensional and inhomogeneous samples testing without accuracy losses.
