Abstract
A sealing ring containing an electrode for sensing electrochemical conditions within a fluid handling system, in particular, the occurrence of crevice corrosion, has a body formed of a continuous loop of an electrically insulating fluid-impervious material having a surface which can form a fluid-tight seal with elements of a fluid handling apparatus, an electrode embedded within the body and electrically insulated from electronic conductive contact with those portions of the surface of the body that contact the fluid handling apparatus, and channels extending between the electrode and the surface of the body of the sealing ring to permit electrochemical contact between the electrode and the fluid within the system. The sealing ring also includes electronically conductive wires to connect the embedded electrode to external electrical devices, e.g., electronic measuring equipment.
