Abstract

Kanał światłowodowy stanowi szczelny przewód ochronny (2), umieszczony wewnątrz odcinka rurociągu (1) do ciśnieniowego przesyłu cieczy, w którym to przewodzie jest umieszczony co najmniej jeden światłowód (3). Przewód ochronny (2) jest wykonany z elastycznego materiału podatnego na odkształcenie pod wpływem zmiany ciśnienia w rurociągu (1), a jego wnętrze jest wypełnione gazem pod ciśnieniem. Przewód ochronny (2) jest zamocowany wzdłuż ścianki rurociągu (1) powyżej jego osi, a szczelne króćce (4) wykonane w ściance rurociągu (1), przez które światłowód (3) jest wyprowadzony na zewnątrz, są wyposażone w manometr (5) do kontroli ciśnienia i zawór (6) umożliwiający zmianę ciśnienia wewnątrz przewodu ochronnego (2).The fiber-optic channel is a sealed protective conductor (2), placed inside a section of the pipeline (1) for pressure transmission of liquids, in which at least one optical fiber (3) is placed. The protective conductor (2) is made of flexible material susceptible to deformation due to pressure changes in the pipeline (1), and its interior is filled with gas under pressure. The protective conductor (2) is attached along the wall of the pipeline (1) above its axis, and the tight connectors (4) made in the wall of the pipeline (1) through which the optical fiber (3) is led outside, are equipped with a pressure gauge (5) for pressure control and valve (6) enabling pressure change inside the protective conductor (2).
