Immersion disposable fast thermocouple head/tip

According to the thermoelectric effect of the metal, the temperature difference between the two ends of the thermocouple is used to measure the temperature of molten steel and high molten metal. That is, two conductors with different compositions are welded at both ends to form a loop. The direct measurement terminal is called the working terminal (hot terminal) and the terminal terminal is called the cold terminal. When there is a temperature difference between the hot terminal and the cold terminal, a thermal current will be generated in the loop. Connect the display instrument, and the instrument will indicate the heat generated. The corresponding temperature value of the electromotive force, the electromotive force increases as the temperature rises.

1. According to the measured object and range, selecting the appropriate protection tube length and suitable temperature measuring gun.

2. Put the fast thermocouple on the temperature measuring gun, and the secondary instrument pointer (or digital) back to zero, this shows contacts good, can be measured.

3. Fast thermocouple insertion depth of the molten steel with 300-400 mm, don't test to furnace wall or dreg , do fast, steady, accurate, when secondary instrument to get the results, should immediately carry guns, fast thermocouple immersion time in molten steel must not exceed 5 seconds, otherwise easy to burn temperature measuring gun.

4. Raised temperature measuring gun from the furnace, take the used thermocouple down, and install a new one, pause for a few minutes, prepare the next measurement. Don't even measure even split, otherwise cause temperature fluctuations.
