The electrode probe (10) is suited for employment as a reference electrode in a high pressure, high temperature, and high radiation field environment such as adjacent the core of a nuclear reactor. The electrode is a brazed and welded assembly comprising ceramic and metal parts including a sapphire crucible (12) which is brazed to a kovar/stainless steel housing, (16, 18), welded in turn, to a coaxial cable assembly (20) for signal transfer. The crucible incorporates an integrally formed pedestal (30) through which a conductor wire (36) extends and over which is positioned a selectively coated cylindrically shaped sealing retainer (42). The device is particularly suited for employment with a silver/silver chloride electrode system. |
