Ceramic carrier based sensor, for measurement of physical parameters, particularly in difficult media, has metal electrode partially embedded in a high melting point ceramic insulating material

摘要

A ceramic carrier based metal sensor electrode system has a high melting point, insulation layer (3), e.g. alumina or glass ceramic, covering a carrier (1) and extending into metal electrodes (2). The electrodes are metal of high melting point, e.g. platinum, tungsten or palladium.
