Embodiment Construction

[0046] One or more specific embodiments of the invention are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation may be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints. Purposes, which may vary from one implementation to another. Furthermore, it should be appreciated that such a development effort might be complex and time consuming, but would not be a routine undertaking of design, production and fabrication for those of ordinary skill having the benefit of this disclosure.

[0047] When introducing elements of various embodiments of the invention, the articles "a," "an," "the," and "said" are intended to mean that there are on...

Abstract

The invention provides components with protected strain sensors and methods for manufacturing the same. Components (10) can comprise a substrate (11), a protected strain sensor (40) comprising at least two reference points (41, 42) disposed on the substrate (11), and a peripheral coating (50) disposed on the substrate (11) adjacent the protected strain sensor (40), wherein the peripheral coating (50) covers at least a portion of an exterior edge (49) of the protected strain sensor (40).

Description

technical field [0001] The subject matter disclosed herein relates to strain sensors, and more particularly to components with protected strain sensors and methods for monitoring the same. Background technique [0002] Some components may need to operate in environments that include elevated temperatures and / or corrosive conditions. For example, turbines are widely used in fields such as power generation and aircraft engines. Such a gas turbine system includes a compressor section, a combustor section, and at least one turbine section. The compressor section is configured to compress air as it flows through the compressor section. The air then flows from the compressor section to the combustor section where it is mixed with fuel and combusted, producing a hot gas flow. The hot gas flow is provided to the turbine section, which uses the hot gas flow to power compressors, generators, and various other loads by extracting energy therefrom. [0003] During operation of a gas...
