Claim 19:
20. 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
the optical fiber is configured to receive thermal radiation from a molten metal bath and convey the thermal radiation to a detector.
