Abstract
PURPOSE: To reduce calorific power by dividing a liquid level sensor, used for a liquid-helium liquid level indicator, etc., into several in its length direction, and then by supplying a current only needed split liquid level sensors.
CONSTITUTION: Liquid level sensor 1 whose lower half part is dipped in liquid He3, for example, comtained in cryostat 2 is provided and sensor 1, consisting of upper- terminal connection part 1a, lower-terminal connection part 1d, and intermediate connection parts 1b and 1c, is connected at connection parts to indicator 4 and constant-current source 5, but those connections are changed over by alternation switch 6. Now, when the liquid level of liquid He is between connection parts 1c and 1d or 1b and 1c, switch 6 is changed over correspondingly to provide measurement without reference to the liquid level, besides the advantage that only a small number of lead wires are required.
