For liquid helium measurement, see our liquid helium level sensors . Construction is stainless steel.
Operation is capacitance-based using cryogenic liquid as the dielectric.
As liquid level changes, the varying capacitance is interpreted by a Cryomagnetics' liquid cryogen monitor as an easily understood readout. For the latest in liquid cryogen level measurement instrumentation, please check out our Model LM-500 Liquid Cryogen Monitor . To order a capacitance-based liquid cryogen level sensor, please refer to the above drawing and specify the active length required. Standard active lengths are available up to 250 centimeters. Longer lengths and custom sensors are quoted per your specifications.
