Temperature is one of the main parameters that determine the quantitative and qualitative indicators of products. Therefore, it is difficult to name a field of technology or a branch of industry where it would not be necessary to measure the temperature of solid, liquid, or gaseous substances.
In order to reduce the uncertainty of the result obtained during the measurement of high temperatures by thermoelectric transducers in the adverse conditions of operation, particulary in case of rapid thermal changes, the influence of mechanical deformation of thermoelectrodes on the change of their thermoelectric power is analyzed. Taking into account that the energy spectrum of electrons in metals is determined by their number and potential of a crystalline lattice, we assume that in the case of elastic deformation with displacement of ions, the lattice potential also varies.
