Abstract

Methods of self-validation have been developed to determine and counter the impact of the drift, but very little is understood about the processes which lead to the drift occurring. To address this issue, NPL has performed controlled tests to shed some light onto the chemical reactions which occur when a typical high temperature thermocouple (Type C; W-5%Re vs. W-26%Re) is exposed to temperatures up to 2300 °C.
