FIELD: measuring molten metal characteristics. SUBSTANCE: probe has cylindrical measuring head provided with pin and first pin end contracted to form cone inwardly directed along pin. Measuring head is made of materials whose combination yields density exceeding that of molten metal. Sensing element protrudes outside from first pin end of measuring head near the pin; cap closes first end of measuring head and sensing element to shield them from slag. Output conductor is brought out of measuring head and electrically connected on one end to sensing element. It will be good practice to coat slag shielding cap and measuring head with ablation material. Output conductor and shielding hose may be spirally wound on output-conductor supporting tube that contacts second pin end of measuring head. EFFECT: enhanced probe penetration in molten metal. 18 cl, 3 dwg
