Abstract
A temperature measuring device for molten metal includes a porous plug with a first end and an opposed second end, an outer protective sheath with a closed end, an inner protective tube with a closed end, and a thermocouple arranged within an interior of the inner protective tube. The outer protective sheath extends away from the first end of the plug and the inner protective tube is arranged within an interior of the outer protective sheath. The porous plug comprises a substantially refractory material and the outer protective sheath consists essentially of substantially refractory metal oxide and graphite. A junction of the thermocouple is proximate to the closed end of the inner protective tube.
