“…In contrast to the method of correction of the error due to acquired thermoelectric inhomogeneity considered in [48], this method does not correct the error due to drift a TC CC. However, it makes it possible to apply the known methods of correction of the error due to drift of a TC CC listed in [47], generalized in [50] and developed in [51]. In this case, in contrast to the correction method [48], the considered method of compensation creates almost ideal conditions for the use of the methods for correcting the error due to drift of TC C, because all sections of a TC under any changes in the temperature field of the object, remain at the temperature of constant operation.…”

“…It is necessary to stabilize the profile of a temperature field along the legs of the TC, which measures the temperature of an object, to implement the method of compensation of the effect of acquired inhomogeneity of TC legs proposed in [48,50]. The stabilization can be achieved by creating an independent temperature field for the TC, measuring the temperature of the object (the main thermocouple), by means of auxiliary temperature control systems.…”

“…This occurs for long-term changes of a temperature field, when temperatures of TC sections after the change in the temperature field, will be perceived by these TC sections as new operating temperatures. In this case the method of compensation of changes in the temperature field along the legs of the TC which measures the temperature of an object [48,50] is more effective. The method is based on one of the fundamental properties of the inhomogeneity [22] if there is no change in the profile of a temperature field along TC legs, then their acquired inhomogeneity, no matter how large it is, can neither manifest itself nor cause error of temperature measurements.…”

Abstract. The method of compensation of changes in temperature field along the legs of inhomogeneous thermocouple, which measures a temperature of an object, is considered in this paper. This compensation is achieved by stabilization of the temperature field along the thermocouple. Such stabilization does not allow the error due to acquired thermoelectric inhomogeneity to manifest itself. There is also proposed the design of the furnace to stabilize temperature field along the legs of the thermocouple which measures the temperature of an object. This furnace is not integrated with the thermocouple mentioned above, therefore it is possible to replace this thermocouple with a new one when it get its legs considerably inhomogeneous.. There is designed the two loop measuring system with the ability of error correction which can use simultaneously a usual thermocouple as well as a thermocouple with controlled profile of temperature field. The latter can be used as a reference sensor for the former.

The method of study and experimental researches of the error of method of the thermocouple with controlled profile of temperature field along the main thermocouple are considered in this paper. Experimentally determined values of error of method are compared to the theoretical estimations done using Newton's law of cooling. They converge well.Keywords: Thermocouple, inhomogeneity of thermocouple, controlled profile of temperature field, measurement error, error of method.
