Abstract A superconducting magnesium diboride (MgB<sub>2</sub>) level sensor for liquid hydrogen has been timely noted as a new sensor from a viewpoint of the worldwide storage and transport of large quantities of hydrogen. The external-heating-type level sensors (200 and 800 mm long) based on MgB<sub>2</sub> wires are fabricated by an in situ method, and their level-detecting characteristics are studied in comparison with the actual liquid level using the liquid hydrogen experiment facility (LHEF). It becomes evident that an external-heating-type MgB<sub>2</sub> level sensor has a high linearity, a small measurement error, and a good reproducibility even in the pressure range of up to 200 kPaG despite the evaporation loss caused by the heater used.
