Abstract
There is provided an expendable device for use with a standard immersion sensor for a molten metal bath to simultaneously hold a standard immersion sampler in juxtaposition to the sensor when the sensor is in its protective sleeve at the end of a lance ready for immersion into the bath. This device provides another expendable heat insulating protective sleeve for accepting in its end the sampler with means being provided for maintaining a side by side relationship between the sampler sleeve and the sensor sleeve during immersion. This combination may advantageously have a vent pipe extending between the sleeves to allow air displaced from the sampler by influx of the sample to vent to a region above the molten metal bath by way of a passage in the sensor sleeve.
