Title (DE) TEMPERATURSENSORANORDNUNG
(EN) TEMPERATURE SENSOR ARRANGEMENT
(FR) ENSEMBLE CAPTEUR DE TEMPÉRATURE
Abstract:
(DE) Es wird eine Temperatursensoranordnung für Gasturbinen angegeben, die eine Messlanze von beispielsweise 3m Länge umfasst. Die Messlanze weist eine Bohrung auf, in der ein Stahlröhrchen axial beweglich geführt ist. Das Stahlröhrchen beinhaltet eine Glasfaser mit Bragg-Gitter-Messstellen zur Messung der Temperatur. Längliche Messöffnungen erlauben das Durchströmen von heißem Gas durch die Messlanze, wobei dabei das Stahlröhrchen im Bereich der Bragg-Gitter-Messstellen umströmt wird.
(EN) 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.
(FR) L'invention concerne un ensemble capteur de température conçu pour des turbines à gaz, comprenant une lance de mesure de longueur égale à 3m par exemple. Cette lance de mesure comprend un orifice dans lequel un petit tube en acier peut être guidé selon un mouvement axial. Ce petit tube en acier renferme une fibre optique pourvue de points de mesure à réseau de Bragg pour mesurer la température. Des ouvertures de mesure longitudinales permettent à un gaz chaud de traverser la lance de mesure, et donc de s'écouler tout autour du petit tube d'acier dans la zone des points de mesure à réseau de Bragg.
