Decreasing of thermocouple inhomogeneity impact on temperature measurement error

Ma Ning, Orest Kochan, Su Jun, Volodymyr Kochan

Abstract

One of the most effective methods of reducing the impact of error due to acquired thermoelectric inhomogeneity of thermocouples' electrodes is discussed in this article. The method consists in stabilizing the profile of the temperature field along electrodes of the main thermocouple (which measures the temperature of the object). There is also discussed the design of device for profile stabilization of the temperature field and methods for control this profile.
