Abstract
A device for measuring the temperature of a melt, particularly of a molten metal, includes an optical fiber and a guiding tube having an immersion end and a second end opposite to the immersion end. The optical fiber is partially arranged in the guiding tube. An inner diameter of the guiding tube is larger than an outer diameter of the optical fiber. A first plug is arranged at the immersion end of or within the guiding tube proximate the immersion end of the guiding tube. The optical fiber is fed through the first plug and the first plug reduces a gap between the optical fiber and the guiding tube.
Claims8
A device for measuring the temperature of a melt comprising:
- a guiding tube having an immersion end and a second end opposite to the immersion end,
- an optical fiber partially arranged in the guiding tube, an inner diameter of the guiding tube being larger than an outer diameter of the optical fiber, and
- a first plug having a first end and an opposing second end, an inner diameter of the first plug being reduced from the second end of the first plug toward the first end of the first plug,
- wherein the first plug is arranged at the immersion end of the guiding tube or within the guiding tube proximate the immersion end of the guiding tube, and
- wherein the optical fiber is fed through the first plug and the first plug reduces a gap between the optical fiber and the guiding tube.
