Abstract
A temperature sensor arrangement for gas turbines is provided. The temperature sensor arrangement has a measuring probe. The measuring probe has a bore in which a steel tube is guided so as to be axially movable. The steel tube includes a glass fibre having Bragg grating measurement points for measuring the temperature. Elongate measurement openings enable hot gas to flow through the measuring probe, flowing round the steel tube in the region of the Bragg grating.
Claims15
A temperature sensor arrangement for a gas turbine, comprising
- a support tube comprising a bore in an axial direction, an outer part, and an inner part composed of segments, the segments respectively having at most half a length of the outer part,
- a guide element arranged movably in an axial direction in the bore, and
- an optical waveguide arranged in the guide element and having at least one Bragg grating measurement point.
A temperature sensor arrangement for a gas turbine, comprising
- a support tube comprising an inner part and an outer part, the support tube defining a bore in an axial direction and measurement openings transverse to the axial direction,
- a guide element arranged movably in an axial direction in the bore, and
- an optical waveguide arranged in the guide element and comprising at least one Bragg grating measurement point,
- wherein the guide element is arranged in the support tube such that the Bragg grating measurement points are disposed in the measurement openings.
