CORROSION SENSOR FOR INTERNAL STRUCTURE OF MACHINE

摘要

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.

1. A corrosion sensor for an internal structure of a compressor, the corrosion sensor comprising:
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 compressor exposed to an operational environment at least similar to that of the internal structure and defining an opening; a mount to secure the test cap in position in the opening in the portion of the 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.
