Abstract
A monitored anode apparatus is provided. The apparatus includes a metal body having an exterior and a core, and a plurality of electrically conductive probes passing through the exterior and disposed at respective depths within the core. At least one of the plurality of conductive probes is disposed at a first depth, and at least one of the plurality of conductive probes is disposed at a second depth greater than the first depth. A bonding conductor is in electrical communication with the body and configured to create electrical continuity between the body and a protected structure. The metal body is configured as a galvanic anode, and at least one of the plurality of probes is configured to break electrical conductivity with the body upon galvanic consumption thereof.
