Effect of Electrical Annealing to the Inhomogeneity Improvement of Type-S Thermocouples

The thermoelectric inhomogeneity as a function of position along wires is one the significant uncertainty of measurement using thermocouples.

Description
Summary:The thermoelectric inhomogeneity as a function of position along wires is one the significant uncertainty of measurement using thermocouples. Here we report development of an electrical annealing system for thermoelectric inhomogeneity treatment. Two inhomogeneous type-S thermocouples, which had the inhomogeneity greater than 0.04%emf, are successfully recovered using the system. An improvement on thermocouple performance as large as 0.28 °C (at temperature of 1000 °C) can be obtained using the system. This article provides detailed information and may help the reader to obtain a quick grasp about the system.
