Abstract

The purpose of this study was to present data on thermistors as sensors for temperature measurements in cryogenic liquids, especially liquid hydrogen. Because of their very large temperature coefficient of resistance, thermistors can be used as highly sensitive temperature sensors. This high sensitivity permits a high degree of simplicity, and hence reliability, in associated readout equipment. A preliminary investigation was made of the use of thermistors for measurement of stratification temperatures in liquid nitrogen and liquid oxygen. This was followed by stratification temperature measurements in liquid hydrogen. These results were successful, and encouraged the recent and more extensive investigation of liquid-hydrogen temperature measurement by thermistors.
