Abstract
A temperature sensor according to the disclosure herein includes an optical fiber structured to produce a thermal emission representative of a molten steel into which the temperature sensor is inserted; a cladding layer covering at least a portion of the optical fiber; and a spectrometer configured to receive the thermal emission from the optical fiber and to generate, in response, a radiation spectrum indicative of a temperature of the molten steel.
Claims22
A temperature sensor comprising:
- an optical fiber structured to produce a thermal emission representative of a molten steel into which the temperature sensor is inserted;
- a cladding layer covering at least a portion of the optical fiber;
- a refractory housing covering at least a portion of the cladding layer, wherein the refractory housing includes at least two layers of increasing thickness arranged from an inner layer closest to the optical fiber to an outer layer;
- and
- a spectrometer configured to receive the thermal emission from the optical fiber and to generate, in response, a radiation spectrum indicative of a temperature of the molten steel.
A temperature sensor comprising:
- a sapphire optical fiber structured to produce a thermal emission in response to exposure to a heated material;
- a spectrometer coupled to the sapphire optical fiber and configured to generate a radiation spectrum based on the thermal emission;
- a cladding layer proximate the optical fiber, the cladding layer comprising a nanoporous material;
- and
- a multi-layered refractory housing covering at least a portion of the cladding layer.
A temperature sensor comprising:
- an optical fiber structured to produce a thermal emission representative of a heated material into which the temperature sensor is inserted;
