Liquid Level Sensor Device for Liquefied Gas |
摘要 |
An object is to provide a liquid level sensor device for liquefied gas enabling measurement on a liquid level of liquefied gas having a boiling point in the vicinity of 21 K, e.g. liquid hydrogen, accurately and with good reproducibility and enabling simple production with good reproducibility. The present invention is a liquid level sensor device for liquefied gas including compound containing magnesium and boron arranged in succession in the longitudinal direction over the entire or a part of surface of a linear conductor made of metal and a portion of the compound thereof dipped in liquid is in a superconductive state at liquid level measurement.
