Precise temperature measurement above 1000 °C using thermocouples; 310–319

(Full article in PDF format)


Authors

Frank Edler

Abstract

Thermocouples are the most widely used electrical sensors in almost all temperature measurement applications in industry and research. Different types of thermocouples and calibration methods are described. Novel metal-carbon eutectic fixed points, usable for improved calibrations of thermocouples, and first results of their application at Physikalisch-Technische Bundesanstalt are presented.

Keywords

high temperature measurement, thermocouple, eutectic fixed point.
