1. An electrochemical corrosion sensor that provides multiple channels of output voltage signals, comprising:
- an array of substantially similar metallic electrodes arranged such that each electrode has a surface area operable to be exposed to an electrolyte at the site of the corrosion and such that each electrode is electrically insulated from other electrodes, wherein a plurality of the electrodes are operable as anodes and a plurality of the electrodes are operable as cathodes; and
a common electrical lead connecting each electrode through a resistor to a common node, such that a voltage output signal from each electrode may be measured across a resistor associated with the electrode.

Abstract
A sensor array for measuring localized corrosion based on electrochemical reactions is disclosed. The sensor has an array of electrodes that are made from the material of interest. The electrodes are electrically insulated from each other and arranged so that a small area of the electrode contacts a corrosive environment. The voltage outputs across the electrodes connected to the electrodes are measured and used as the signals to indicate localized corrosion.
