Abstract: Thermocouples; the key of precise measurements are considered as the integral part of temperature and emf measuring systems not only in indusial areas but also in research and technical fields. This all is due their normal approach, accurate results and the possibility of their performance in some critical conditions like the molten steel state, metal vapors and the magnetizing processes etc. This report puts an objection on the accuracy of such measurements due to the effect of operating conditions which allow the presence of electric and magnetic fields and sometimes the stress also. The main objective of this research work is to explain how there is alteration of temperature-emf relations which affect the corresponding measurements. Hence this paper informs to take into account the effect of electric field, magnetic field and stress in the operating conditions of thermocouples which alters the temperature-emf relations in the high temperature range of 300K to 600K.
Keywords: Thermocouple, Electric Field, Magnetic field, Stress, Temperature and emf.
