Abstract
A device for measuring a temperature of a molten metal bath, comprising: an optical cored wire; a tube, wherein the optical cored wire is at least partly arranged in the tube, wherein the tube has an outer diameter in the range of 4 mm to 8 mm, and a wall-thickness in the range of 0.2 mm to 0.5 mm; and a plurality of separating elements comprising more than two separating elements arranged in the tube spaced apart from each other, and forming at least one compartment between two of the more than two separating elements. The invention also relates to a system and method for measuring a temperature of a molten metal bath.

A device for measuring a temperature of a molten metal bath, comprising:
- an optical cored wire comprising an optical fiber at least partially surrounded by a first tube made of a metal;
- a second tube, wherein the optical cored wire is at least partly arranged in the second tube, wherein the second tube has an outer diameter in the range of 4 mm to 8 mm, and a wall-thickness in the range of 0.2 mm to 0.5 mm;
- and
- a plurality of separating elements arranged between the optical cored wire and the second tube, wherein
- each of the plurality of separating elements are at least partly gas permeable to allow for the movement of gases therethrough,
- adjacent separating elements of the plurality of separating elements are spaced apart from each other, and
- each of the plurality of separating elements are attached to the optical cored wire or the second tube,
- spaces between the optical cored wire, the second tube and adjacent separating elements of the plurality of separating elements are filled with a filler consisting of a gas or a gas mixture, and
- the optical fiber is configured to receive thermal radiation from a molten metal bath and convey the thermal radiation to a detector.
