Patent ID: 7148706

Claim:
An embeddable system for detecting and measuring corrosion in a structure susceptible to corrosion, said system including a plurality of embeddable corrosion rate meters (ECRM) for collecting corrosion measurements data and at least one computing device for analyzing said corrosion measurements, said system comprising: at least one working electrode evenly separated from a counter electrode, wherein a separation distance between said at least one working electrode and said counter electrode determines an electrolyte medium resistance, said electrolyte medium resistance is less than or equal to a polarization resistance; a signal generator for generating a current source, said current source is connected to a plurality of resistances for creating a plurality of current amplitudes; a first selector for applying current through each of said plurality of resistances to said at least one working electrode and said counter electrode, wherein said current is applied via a galvanostat; an external reader-head with a data link and power link connected to said computing device for powering said ECRM and transferring corrosion measurements data via said data link; and a programmable electronic chip having a voltage output, wherein said chip is programmed to include a voltage-time signal, said voltage-time signal including a plurality of sine waves; and said galvanostat for receiving and converting said voltage output into a current-time perturbation signal.
