The hard operation conditions of temperature thermotransducers which involve their thermal cycling require special attention to the study of processes occurring in structural elements, in particular in thermometric materials. Operation impacts cause the drift of thermometric characteristics due to the influence of the few factors main of which seem to be the thermo structural stresses.
The choice of ways of obtaining information about the temperature of the surface layers of a moving object is the crucial in determining the type of temperature transducers. This choice depends on the row of specific factors: the speed of movement of the measured object relative the object, the state of the surface, the presence of related agents in near-surface layers, the presence of disturbing factors - noise, vibration, etc. The major factor seems to be the value of the heat carried out from the diagnosed object with the help of intermediate substance.
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.
