Latest Patents
Koide's latest patents include a sensor probe designed for measuring hydrogen concentration in molten metal. This sensor probe features an inner surface made of a proton conductive solid electrolyte with a perovskite structure. At its lower end, a reference electrode constituted of a porous electrode is formed, along with a measuring electrode on the outer surface. The reference and measuring electrodes are gas-tightly separated by sealing material. The sensor probe is inserted into a ceramic sensor holding cup, allowing a part of the measuring electrode to extrude into the cup. By dipping the holder into molten metal with its opening facing downwards, a space that contacts the molten metal is enclosed in the holding cup. This design prevents the reduction of the solid electrolyte and allows for accurate measurement of hydrogen concentration without direct contact with the molten metal. The innovation enables continuous measurement of hydrogen concentration over extended periods while maintaining a compact apparatus size.
