WebJan 26, 2024 · Experimental Study on Superconducting Level Sensors in Liquid Helium Abstract: An approach for experimental investigation of the optimum sensor current of a superconducting level sensor is established and is then used for the investigation of the … WebSuperconducting-coil systems are usually contained in metal dewars so that the liquid helium level cannot be viewed directly. The liquid level can be monitored at fixed points by means of various level detectors [ 1–4 ]. However, a simple detector which can give a continuous indication of liquid level is more desirable than fixedpoint detectors.
