Abstract

The actual problem is the theoretical and an experimental research the characteristics of the sensor gauges liquid cryoagents. The appearance high-temperature superconducting materials (HTSC) with superconductivity in the range of 77...135 K can create level meters such widely popular and most widespread cryogenic as liquid oxygen, nitrogen, argon, and liquefied natural gas. In quality HTSC use cuprate materials Bi2212 and Bi2223. The features of these materials, given the characteristics of the sensor, described their physical and mathematical model. The experimentally and by calculation to get a working static volt-linear characteristics of different HTS sensors. It is shown how based on them can provide high measurement accuracy level cryoliquid. Comparison of experimental data with the calculations showed that the difference between them reaches no more than 4 % in the middle of the range of changes in the level of cryoliquid and no more than 13,5 % — at the ends.
