Abstract
A corrosion sensor for an internal structure of a machine is provided. The corrosion sensor may include a test cap having at least one of a material and a geometry configured to fail faster than a material of the internal structure due to a corrosive influence. A mount secures the test cap in position in an opening in a portion of the machine that defines an operational environment. A chamber is adjacent the test cap and in at least one of the test cap and the mount. A failure in the test cap creates an environmental change in the chamber that indicates exceeding a corrosion threshold and can be sensed by, for example, a temperature or pressure change.
