Abstract

Przedmiotem zgłoszenia jest naczynie do pomiaru temperatury, posiadające podstawę i ścianę boczną, które charakteryzuje się tym, że w naczyniu (1) wykonany jest rowek (1.1), w którym ułożony jest światłowód jednomodowy (2) z zapisanymi siatkami Bragga (B). Pierwszy koniec światłowodu (2) podłączony jest do eliminatora odbicia wstecznego (5), a drugi koniec światłowodu (2) podłączony jest do wyprowadzenia cyrkulatora optycznego (3), którego przeciwległe wyprowadzenie podłączone jest do źródła światła (4). Wyjście cyrkulatora (3) połączone jest z układem filtrów dopasowanych (6), który podłączony jest do urządzenia odczytującego (7) umożliwiającego odczyt temperatury na podstawie przesunięcia centralnych długości fali odbitej od siatek Bragga (B).The subject of the application is a temperature measuring vessel having a base and a side wall, characterized in that a groove (1.1) is made in the vessel (1) in which a single-mode optical fiber (2) with recorded Bragg gratings (B) is arranged. The first end of the optical fiber (2) is connected to a back reflection eliminator (5), and the second end of the optical fiber (2) is connected to an output of an optical circulator (3), the opposite output of which is connected to a light source (4). The output of the circulator (3) is connected to a matched filter system (6), which is connected to a reading device (7) enabling temperature reading based on the shift of the central wavelengths reflected from the Bragg gratings (B).
