THE CONSTRUCTION AND CHARACTERIZATION OF PLATINUM-BASED THERMOCOUPLES AT UME

Murat Kalemci, Sevilay Ugur

Abstract

High accuracy measurement of temperature up to 1200°C is an important concept for science, technology and for the industry. For high temperature measurements, thermocouples, which depend on Seebeck principle, are widely used. Platinum based thermocouples are preferred due to their high purity and quality for metrological use. In this paper, the construction of type S and type R thermocouples at UME will be described. After construction, thermocouples were calibrated at the tin, zinc, aluminium and silver freezing points by fixed-point method and by wire-bridge method at gold point.
