DRIFT OF NICKEL BASED MIMS THERMOCOUPLES AT TEMPERATURES ABOVE 1000°C: THE EFFECT OF THERMOCOUPLE DIAMETER

Michele Scervini

Abstract

In this work the drift of type K and type N MIMS thermocouples has been studied as a function of the thermocouple outer diameter in the temperature range 1000 - 1300°C. It is shown that type K and type N MIMS thermocouples drift significantly above 1000°C, the drift being more pronounced for smaller diameters. The data presented in this paper allows to compare the performance of type K and type N thermocouples at high temperatures over a wide temperature range and at different diameters.
