Abstract:
1. A turbine, comprising: a rotor, which is rotatable about a centerline thereof; a sensor mounted on a rotating component 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 as mounted on the rotating component and a portion of the communication system on the rotor proximate to the point of measurement interest, the probe holder comprising a surface and a wiring assembly to hold a section of the portion of the communication system against the surface with relative movement of the section relative to the surface prevented and slack provided along the surface at the probe holder on either side of the wiring assembly and the section, wherein the point of measurement interest is located at an extraction cavity of a forward shaft with a sensor longitudinal axis parallel with a radial dimension of the rotor and the probe holder comprises: a probe holder body having a neck with a radially outward-most face substantially aligned with an inner diameter of the extraction cavity and wings extending circumferentially outwardly from the neck to absorb gravitational loading, the probe holder body and the neck being formed to define a sensor receptive cavity therein with sensor cavity shoulders; and a cap to secure the sensor within the sensor receptive cavity such that the sensor abuts the sensor cavity shoulders and a sensing device thereof aligns with the radially outward-most face and the inner diameter of the extraction cavity.
