Abstract

By means of concrete examples, we discuss the determination of an uncertainty budget for calibration of thermocouples by comparison techniques. In the first example, the calibration of a type T thermocouple (copper versus copper-nickel alloy) in a stirred liquid bath with a platinum resistance thermometer as a reference is considered. The second example is the calibration of a type K (a nickel-chromium versus nickel-aluminum alloy) thermocouple at temperatures up to 1200 C in a tube furnace, using a platinum-rhodium alloy thermocouple as a reference. Methods for determining the magnitudes of these uncertainties are given for each uncertainty component.
