A fast-response, non-splashing thermocouple with a protective cotton tube is utilized for measuring the temperature of molten metal.
This expendable thermocouple consists mainly of a temperature probe and a large paper tube.
The positive and negative wires of the probe are welded to compensation wires housed in a bracket encased by a smaller paper tube.
The hot wire is supported and protected by quartz, while the temperature probe is topped with a lid to prevent scum buildup.
All components are positioned at the thermocouple's end and secured together with a refractory filler.
