Abstract
Ein Faser-Bragg-Gitter-Mehrpunkte-Temperaturmesssystem (44) weist ein Fasermesskabelpaket (52) und mehrere entlang einer Innenoberfläche einer Wand in Umfangsrichtung verteilte Klemmvorrichtungen (50) zum Befestigen des Fasermesskabelpakets auf. Das Fasermesskabelpaket weist ein auf einem Faser-Bragg-Gitter basierendes Messkabel (53) auf, das wenigstens eine optische Faser (12), mehrere in die optische Faser eingeschriebene Bragg-Gitter (14) und eine Gewebelage und ein die optische Faser umgebendes Hüllrohr aufweist. Das Mehrpunkte-Fasermesssystem weist eine Lichtquelle zum Übertragen von Licht an die Bragg-Gitter und ein reflektiertes Licht empfangendes Detektormodul auf. Jede Klemmvorrichtung weist wenigstens ein Strahlungs-T-Stück (54) auf und definiert wenigstens ein Montageloch zum Befestigen des Fasermesskabels.
