Cryogenic Temperature Sensors

This paper describes the different cryogenic temperature sensors used at cryogenic temperatures down to 1 K. The characteristics of these temperature sensors have been discussed in detail with their operating range, sensitivity, and accuracy. Other properties like interchangeability, effect of thermal cycling, effect of ionizing radiation (neutron or gamma ray), effect of magnetic field has also been described. It is extremely important to choose the right temperature sensor for right kind of application in a specific operating environment. This paper gives an overview of some of the most widely used cryogenic temperature sensors.
