Abstract
A preformed refractory sleeve for a temperature sensing device suitable for repeated immersions into molten metal is generally cylindrical in shape. An inwardly directed shoulder is spaced from the immersion end of the sleeve against which shoulder a support tube supporting the temperature sensor may abut and seal. The bore of the sleeve includes a truncated cone-shaped recess between the shoulder and the immersion end of the sleeve through which the bight of the temperature sensor extends. The truncated cone-shaped recess is filled with refractory cement to positively secure the temperature sensor to the sleeve and insulate the temperature sensor. Longitudinal ribs may extend into the bore of the cylindrical sleeve at the end of the sleeve opposite the truncated cone-shaped bore to center the support tube and form insulating air gaps between the sleeve and support tube.
