Abstract: A probe assembly includes a cup including at least one cooling outlet, and a cap including an inlet, the cap affixed to the cup. The probe assembly also includes hypo tubing affixed to the inlet, and a probe disposed within an interior volume of the cup and the cap, the probe including a lead at least partially disposed within the hypo tubing.

Abstract: An adapter includes a cup having an inner portion proportioned to retain a sensor probe such that a face of the sensor probe is exposed to an interior of a gas turbine, where the inner portion includes a sidewall and a lip. The cup also includes one or more channels extending along the sidewall and across the lip. The adapter includes a mounting flange, where the one or more channels are configured to direct a gas from an exterior of the gas turbine across the face of the sensor probe.

Abstract: A lead cooling assembly includes a cooling jacket including a tubular section having an exterior portion and an interior portion, where the interior portion is proportioned to surround a probe lead and provide space for a flow of a gaseous coolant. The lead cooling assembly also includes an intake configured to admit the gaseous coolant into the interior portion of the cooling jacket. The lead cooling assembly further includes a collar configured to fit over the exterior portion of the cooling jacket, where the collar includes one or more exit holes configured to pass the gaseous coolant out of the interior portion of the cooling jacket.

Abstract: An angled face cap probe includes a housing having a radially inner end and a radially outer end, defining a cavity, and configured to be located radially outward from an airfoil. The angled face cap probe further includes a sensor located in the cavity at the radially inner end of the housing, having a sensor body with a sensing face that is angled to match or substantially match an angle of a radially outward face the airfoil, and having a sensor flat that is elongated in a first direction. The angled face cap probe further includes an outer cap located in the cavity, coupled to the housing, and having an outer cap main body and cap legs that extend radially inward from the outer cap main body to interface with the sensor flat to resist rotation of the sensor relative to the housing.

Abstract: A low profile un-lensed non-intrusive stress measurement system probe may comprise a housing comprising a first channel and an optical face, a first hypotube disposed within the first channel and coupled at a sensing aperture in the optical face, and a plurality of optical fibers disposed within the first hypotube, wherein the first hypotube executes a bend between 45° and 90° within the housing.
