  • Patent number: 8998568
    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.

  • Publication number: 20150040567
    Abstract: A turbine assembly is disclosed herein. The turbine assembly may include a rotor with at least one bucket extending radially therefrom. The turbine assembly also may include a stator assembly positioned adjacent to the at least one bucket. Moreover, the turbine assembly may include a seal assembly. The seal assembly may include a first flange extending in a substantially axial direction from the at least one bucket. The seal assembly also may include a second flange extending from the stator assembly in the substantially axial direction opposite the first flange. The second flange may include at least one protuberance projecting towards the first flange.

  • Patent number: 8347698
    Abstract: A sensor is provided and includes a body disposed at a point of measurement interest on a rotor at a radial distance from a centerline thereof and having a substantially cylindrical shape and first and second opposing ends and a sensing end coupled to one of the first and second opposing ends, the other of the first and second opposing ends being coupled to a communication system, the sensing end including a sensing device configured to generate a signal reflective of a detected condition at the point of measurement interest, and at least one of the first and the second opposing ends being formed to define a shoulder portion for absorbing gravitational loading.

  • Patent number: 8220319
    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.

  • Publication number: 20120134782
    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.

  • Publication number: 20120096961
    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.
