ABSTRACT:
A sensor for use in monitoring electrochemical potentials, includes (a) a crucible made of ceramic material having a closed end and an open end, the close end containing metal/metal oxide powder mixture retained therein by mineral insulating packing, the open end having a metallized band fired in the ceramic material; (b) an annular metal sleeve formed of a metal exhibiting a coefficient of thermal expansion compatible with the crucible, and having a distal open end brazed to the open end of the crucible, and a proximal open end; (c) an insulated electrical conductor having a distal end in electrical connection with the metal/metal oxide powder and extending through the mineral insulation packing and into the first annular sleeve, and having a proximal end terminating near the proximal open end of the annular sleeve; and (d) a signal transfer assembly sealingly associated with the proximal end of the annular sleeve including an electrical cable connected to the electrical conductor.
