FIELD: machine building.
SUBSTANCE: device for determination of level of cryogenic liquid consists of a sensor, analysis block and logger. The sensor is manufactured from a thin-walled dielectric plate installed vertically on the vessel base. By the height of the working area of the dielectric plate the measuring units coated with a thin layer of electric insulating material with high heat transfer factor are installed. Each measuring unit contains series connected sensing elements with identical resistance designed from a material with high thermistor sensitivity in the field of cryogenic temperatures, and located on identical distances from each other. The amount of sensing elements in all measuring units is identical.
EFFECT: improvement of accuracy of determination of level of cryogenic liquid in conditions of influence on measured medium of various disturbing effects.
