Abstract

A new configuration of superconducting level sensor for liquid hydrogen is proposed. The proposed sensor has an advantage that it is difficult to be affected by various conditions of gas such as temperature, pressure and object, so that it is expected that the reproducibility of sensor output becomes very good. The operation of the proposed sensor is numerically simulated with a one-dimensional heat balance equation to evaluate the time evolution of temperature distribution for an ideal MgB2 wire. The proposed configuration of sensor with an MgB2 wire with stainless-steel sheath is also fabricated, and its operation is experimentally evaluated with the liquid hydrogen.
