SLX series of deep-cold container temperature testing and the temperature uniformity study

Pt100 of platinum resistance sensor is used to measure the internal temperature of the SLX series deep-cool container, and the conditioning circuit of temperature measurement is given. The temperature of the same temperature point is repeatedly measured to gain the 9 points datum, and the uniformity value of temperature is obtained as compare with the 9 points data under different temperatures point of the device. The temperature experiment shows that the platinum resistance temperature sensor is precise and stabilized to measure temperature under temperature uniformity test, and the proposed method can solve the instability of the previous process of deep cryogenic treatment.
