Abstract
PURPOSE:To perform measurement always in high accuracy by covering the superconductive wire to be put into the liquid helium tank of a liquid helium level gage with a heat insulating film. CONSTITUTION:A superconductive wire 1 covered with a heat insulating film by enamel coating or winding of this tapes of polyester, etc. is provided in the liquid helium tank 2 of a liquid helium level gage. Constant current is flowed from a DC constant current source 4 thereto, and the voltage V is detected. The liquid level of liquid helium 3 is measured with good accuracy by using the relation shown by the equation. Covering the wire 1 makes it possible to prevent the liqud level from being measured higher than the actual level on account of the superconductive state assumed by the conductor 1 near the liquid level by the evaporated He when the rate of evaporation of He is high.
