FIELD: measuring equipment.
SUBSTANCE: device for temperature measurement in metal melts includes thermal element placed in tube, outer protection case made mainly of graphite and metal oxide. Thermal element tube is positioned in the protection case at some distance to form interspace filled with insulating material and oxygen-binding material. Insulating material and oxygen-binding material in the form of powder form a tube surrounding thermal element tube at some distance from it, or surrounded by protection case at some distance from it.
EFFECT: improved operation characteristics of device.
