Abstract : 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.
