Non Splashing Thermocouple

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.

Usage

● Choose an appropriate length of protective paper tube and a suitable temperature measuring gun based on the measurement object and scope.

● Attach the fast thermocouple to the temperature measuring gun and reset the pointer (or digital display) of the secondary instrument to zero. This indicates a proper connection and readiness for measurement.

● Insert the fast thermocouple into the molten steel to a depth of 300-400 mm. Avoid measuring against the furnace wall or slag to ensure quick, stable, and accurate readings. The immersion time in molten steel should not exceed 5 seconds to prevent damage to the temperature measuring gun.

● After removing the temperature measuring gun from the furnace, detach the used thermocouple and replace it with a new one. Allow a few minutes for a pause before preparing for the next measurement. Continuous measurement and removal are not recommended, as this may cause temperature fluctuations.
