  • Patent number: 5896432
    Abstract: An electrochemical corrosion potential sensor is fabricated by initially joining an electrical conductor to a sensor tip. An electrical cable is joined to the tip conductor. Ceramic powder is fused under heat around the tip conductor to form an integral annular electrically insulating band therearound to insulate the tip from the cable. The band may be formed by plasma spraying, or it may be molded and sintered to seal it to the tip and conductor without brazing. In a preferred embodiment, the band is formed of yttria-stabilized-zirconia or magnesia-stabilized-zirconia.

The contact assembly includes two contact pads per electrical phase, with one of the contact pads being attached to a positioning device that selectively disposes the contact pad between a closed circuit position and an open circuit position. The high recovery voltage gas system includes a thermal gas evolving medium for introducing a high recovery voltage strength gas into the gap between the contact pads, which gas has a high glow discharge cathode voltage fall value, as determined for silver-based contacts, of not less than about 300 volts, and typically greater than about 500 volts. The high recovery voltage strength gas typically comprises carbon monoxide, carbon dioxide, water vapor, or the like.
