Abstract
Corrosion sensor apparatus for detection of contamination affecting metal based components and devices. For example, an apparatus includes: a set of corrosion sensor elements wherein a width of a first corrosion sensor element is different than a width of a second corrosion sensor element, wherein each corrosion sensor element is susceptible to corrosion caused by an operating environment of the corrosion sensor elements; and a set of reference elements wherein a width of a first reference sensor element is substantially equal to the width of the first corrosion sensor element and a width of a second reference sensor element is substantially equal to the width of the second corrosion sensor element, wherein each reference sensor element is not substantially susceptible to corrosion caused by the operating environment of the corrosion sensor elements.
