Embodiment Construction
[0036] from figure 1 A part of the main body of the temperature measuring member 1 comprising a base body 2 a made of a basic material 2 is evident as the first embodiment. Three optical waveguides 3 , one of which is surrounded by a protective tube or tube 4 , are arranged on a predetermined and fixed surface of the base body 2 a that delimits or insulates the area of the base material 2 , which is the measurement surface. It should be noted here that the temperature component 1 usually only comprises similar optical waveguides 3 , which means either these with or without the surrounding tube 4 . The optical waveguide 3 is placed sealingly on the base material 2 of the base body 2a and fixed in its position by means of a cladding 5 formed of cladding material 5a, preferably metal, and is tightly, hermetically, evenly covered by the cladding 5 surrounded. The thickness or strength of the cladding 5 corresponds to approximately 200-250 μm and thus corresponds approximately ...

Abstract
The invention relates to a method for integrating an optical waveguide (3) of a temperature sensor and / or strain sensor into a temperature and / or strain measuring component (1) made of a base material (2), onto which a coating (5) is applied. The optical waveguide (3) is arranged on a predetermined measurement plane, whereupon a coating (5) is applied. The aim of the invention is to allow an optical waveguide (3) to be accurately integrated into and tightly joined to the body of a temperature and / or strain measuring component (1). Said aim is achieved by arranging the optical waveguide (3) within, on top of, or on a plane of the temperature and / or strain measuring component (1), said plane delimiting the base material (2) of the temperature and / or strain measuring component (1) and forming a predetermined measurement plane, and then applying a coating material (5a) to said plane of the temperature and / or strain measuring component (1) made of the base material (2) such that the coating is formed which integrally joins the optical waveguide (3) or a tube (4) surrounding the optical waveguide (3) to the base material (2) and / or to adjacent coated zones.
Description
technical field [0001] The invention is directed to an optical waveguide (Lichtwellenleiter) for bonding a temperature measuring sensor and / or a strain measuring sensor to a temperature measuring component made of a base material (Grundwerkstoff) with a coating (Beschichtung) applied thereon And / or the method in a strain-measuring component, wherein the optical waveguide is arranged in the provided measuring plane and is subsequently coated with a covering coating. [0002] Furthermore, the invention relates to a measuring component with an integrated optical waveguide of a temperature measuring sensor and / or a strain measuring sensor, made of a base material with a coating applied thereon, wherein the optical waveguide is arranged In the provided measuring plane and covered by the coating. Background technique [0003] It is known to use optical waveguides for temperature measurement and to install them in temperature-measuring components. Such temperature components can ...
