Patent Images
1. A hot gas path measurement apparatus, comprising:
- a substrate having a coating applied on a substrate surface thereof such that the coating is interposed between the substrate and a hot gas path; and
a measurement device fixed in a recess formed in the substrate, the recess being formed such that portions of the substrate surface outside the recess are disposed at a first plane and portions of the substrate surface in the recess are disposed at a second plane and are recessed from the first plane, the measurement device including;
a sensor, anda holder configured to position the sensor in an alignment condition with a plane of a surface of the coating or at least partially within a span of the hot gas path, the holder comprising;
an insulator having an insulator recess formed therein to extend from the second plane to at least the plane of the surface of the coating; and
a holding agent disposed to secure the sensor in the insulator recess in the alignment condition.

8. A hot gas path temperature measurement apparatus, comprising:
-
a base metal having a thermal barrier coating (TBC) applied on a base metal surface thereof such that the TBC is interposed between the base metal and a hot gas path; and a temperature measurement device fixed in a recess formed in the base metal, the recess being formed such that portions of the base metal surface outside the recess are disposed at a first plane and portions of the base metal surface in the recess are disposed at a second plane and are recessed from the first plane, the temperature measurement device including; one or more of a thermocouple and a thermal crystal disposed in an alignment condition with a plane of the surface of the TBC or at least partially within a span of the hot gas path, and a holder configured to position the one or more of the thermocouple and the thermal crystal in the alignment condition with the plane of the surface of the TBC or at least partially within the span of the hot gas path, the holder comprising; an insulator having an insulator recess formed therein to extend from the second plane to at least the plane of the surface of the TBC; and a holding agent disposed to secure the sensor in the insulator recess in the alignment condition. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for use in a measurement of a hot gas path, the method comprising:
-
applying a coating to a surface of a substrate such that the coating is interposed between the substrate and a hot gas path; forming a recess in the coating and the substrate such that portions of the surface of the substrate outside the recess are disposed at a first plane and portions of the surface of the substrate in the recess are disposed at a second plane and are recessed from the first plane; and fixing a measurement device in the recess such that a sensor thereof is in an alignment condition with a plane of a surface of the coating or at least partially within a span of the hot gas path, the fixing comprising; disposing an insulator in the recess, the insulator having an insulator recess formed therein to extend from the second plane to at least the plane of the surface of the coating; and securing the sensor in the insulator recess in the alignment condition with a holding agent. - View Dependent Claims (17)
