Abstract

In the paper comparison of a non-pressure controlled caesium heat pipe with a fluidised bath containing alumina powder is presented. Both the heat pipe and the fluidised bath are used for calibration by comparison of contact thermometers (resistance thermometers, thermocouples, indication thermometers). Emphasis of comparison was on temperature stability, homogeneity of temperature (axial and radial gradients), usable depth, operating temperature range, maintainability, commercial availability, price and possibility of using a particular device for other purposes than calibration by comparison.
