Summary
Reliability of liquid helium level sensors becomes critical whenever a cryostat needs to be completely welded and accessibility becomes limited. This paper presents a review of the currently available continuous LHe level sensors from the viewpoint of reliability and wide operating temperature range (1.5 - 5.0 K). The only in limited temperature segments 3.0 - 4.6 K and below the lambda-point. Specifications of a new, simple and wide temperature range level sensor which dissipates very low power (~ 6 mW) into the cryogenic system and that can measure level of any cryogenic liquid are also presented here.
