APPARATUS AND METHOD FOR MEASURING HYDROGEN CONCENTRATION IN MOLTEN METALS
摘要
<p>A probe for measuring hydrogen concentration in molten metals comprises a probe body and a hydrogen sensor. The sensor structure is based on a sensor body having a wall within which a sealed cavity is defined. The cavity contains a solid reference material for generating a reference partial pressure of hydrogen within the cavity. At least a portion of the wall of the cavity is formed from a solid electrolyte material carrying a measurement electrode on a surface of the solid electrolyte outside the cavity and a reference electrode on a surface of the solid electrolyte within the cavity, exposed to the reference partial pressure of hydrogen. An electrical conductor extends from the reference electrode through the wall of the cavity to an external surface of the sensor body. The probe body comprises a chamber for receiving the sensor and a reference-signal connection for connecting to the electrical conductor when the sensor is received in the chamber.</p>
