ABSTRACT:
An improvement is provided in thermocouple apparatus for indicating liquid level in a container, particularly a continuous casting mold. The conventional apparatus includes a plurality of thermocouple elements of first polarity connected to the container at spaced levels above and below the liquid and to corresponding spaced points on a slide wire resistor. The container wall acts as the thermocouple element of opposite polarity. A conductor probe is connected to the wall and to a point on the resistor above the uppermost thermocouple element to provide a reference voltage at that point. The probe and thermocouple elements extend to locations adjacent the exterior face of the container which may be subject to substantially variable ambient temperature. The improvement of this invention involves substitution of a portion of the length of either the probe or the thermocouple elements with, a material substantially equivalent to the thermocouple element of first polarity in the case of the probe, or a conductor material equivalent to that of the probe in the case of the thermocouple elements. The substituted portions extend from an internally cooled region of the wall of the container to a location adjacent the exterior of the wall.
