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.
Claims19
A corrosion sensor and gas turbine compressor system, the system comprising:
- a gas turbine compressor with an internal structure;
- 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 portion of the gas turbine compressor defining an opening and exposed to an operational environment at least similar to that of the internal structure;
- a mount to secure the test cap in position in the opening in the portion of the gas turbine compressor whereby the test cap is exposed to an operational environment at least similar to that of the internal structure;
- and
- a chamber adjacent the test cap and in at least one of the test cap and the mount,
- wherein an environmental change in the chamber caused by a failure of the test cap indicates exceeding a corrosion threshold.

- 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 portion of the gas turbine compressor exposed to an operational environment at least similar to that of the internal structure and defining an opening;
- a mount coupled to the test cap to threadably secure the test cap in position in the opening in the portion of the gas turbine compressor exposed to an operational environment at least similar to that of the internal structure;
- and
- a chamber adjacent the test cap and in at least one of the test cap and the mount,
- wherein an environmental change in the chamber caused by a failure of the test cap indicates exceeding a corrosion threshold,
- wherein the mount positions the test cap in the position such that the test cap is exposed to a stress greater than the internal structure.
