Abstract

The paper deals with the calibration of PRT-s heaving w <1>

A cryostat using a gas thermometer as a primary temperature sensor is presented.

After presentation of the gas thermometer's principle, ist equation and a brief review on the terms involved is given.

The paper presents also a discussion on the constructive details, the heat transfer and the control of the cryostat.

Finally the accuracy of temperature control and an example pf PRT's temperature curve is given.
