Document Type and Number:
WIPO Patent Application WO/2012/171799
Kind Code:
A3
Abstract:
The invention relates to a temperature sensor arrangement for gas turbines which comprises a measuring probe having a length of 3m, for example. 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.
