International Classification:

G01D 21/00

US Classification:

7311201

Abstract:

A communication system is provided and includes a sensor to measure a condition at a point of measurement interest defined on a rotor of a turbine at a radial distance from a centerline about which the rotor is rotatable, wiring disposed on the rotor at a radial distance from the centerline, the wiring including a first wiring section coupled to the sensor, a second wiring section and a first connection by which the first and second wiring sections are connectable, a second connection by which the second wiring section transmits a signal reflective of the detected condition to a non-rotating recording element and a temperature compensation module disposed on the second wiring section to adjust the signal.

US Classification:

73756, 738665

Abstract:

A turbine is provided and includes a rotor, which is rotatable about a centerline thereof, a sensor to measure a condition at a point of measurement interest defined on the rotor at a radial distance from the centerline, a communication system by which condition measurements are transmittable from the sensor to a non-rotating recording system and a probe holder to secure the sensor and a portion of the communication system on the rotor proximate to the point of measurement interest.

US Classification:

738665

Abstract:

A turbine is provided and includes a component having a body, which is rotatable about a rotor centerline and which is formed to define a cavity radially proximate to a point of measurement interest defined at a radial distance from the centerline, a sensor to measure a condition at the point of measurement interest, a communication system by which condition measurements are transmittable from the sensor to a non-rotating recording system and a probe holder insertible into the cavity to secure the sensor proximate to the point of measurement interest.

B23P 19/00

US Classification:

415145, 29700

Abstract:

A method for assembling a rotary machine includes providing a first rotatable element. The method also includes coupling a second rotatable element to the first rotatable element. The first rotatable element and the second rotatable element at least partially define a cavity therein and at least one conduit extending substantially axially therebetween. Further, the method includes coupling a purge device including at least one radial channel defined therein and extending to the first rotatable element and to the second rotatable element such that the at least one radial channel is coupled in flow communication with the cavity and with the at least one axial conduit.
