THERMODYNAMIC METHODS OF HIGH-TEMPERATURE MEASUREMENT

Abstract

Thermodynamic temperature measurement techniques fall into three separate classes: pneumatic devices, heat-transfer gages, and calorimetric methods. All three are characterized by the ability to measure temperatures (or related fluid properties such as enthalpy) at levels beyond the capability of thermoelectric materials or pyrometer calibration devices. This report reviews the principle of operation, present status, range of applicability, and performance of each of these thermodynamic temperature and enthalpy-measuring techniques. In many instances, particularly when opaque gases or high temperature gradients are present, the thermodynamic probes represent the only suitable method for measurement of extremely high gas enthalpies and temperatures.
