A fast thermocouple use and works:
Fast thermocouple for measuring the temperature of molten steel and high-temperature molten metal, disposable consumable thermocouple. It's working principle is based on metal thermoelectric effect, the use of temperature difference generated at both ends of the electric thermocouple measurement of molten steel and high melting metal temperature.
Second, product specifications and performance comparison:
Model, sub-degree numbers
Temperature upper limit
Platinum and rhodium 30 - 6 platinum and rhodium
Platinum and rhodium 10 - platinum
Platinum and rhodium platinum and rhodium 13 platinum
Rhenium, tungsten rhenium 25 3-
Third, the structure:
Fast thermocouple structure, it is mainly by temperature even head and large paper tube. Even head mainly on the positive and negative thermocouple wire welding wire compensation, compensation wire wear embedded in the stents, stent coat a small paper tube, thermocouple wire quartz support and protection. The outermost equipped with anti slag cap, all components centralized load dump and fire-resistant filler bonded into a whole, and not removable, it is disposable.
The use of methods
1, according to the object and scope of the survey, select the appropriate paper tube length and the protection applicable temperature gun.
2, the rapid temperature thermocouple mounted on the gun, and secondary instrument pointer (or digital device) back to zero, then the description of good contact, can be measured.
3, fast thermocouple inserted steel depth of 300-400mm is appropriate, when measured not measured on the furnace wall or slag, to: fast, stable, accurate, when the secondary instrument to get results, you should put the gun immediately, fast thermoelectric Even in the molten steel immersion time shall more than five seconds, or easily burn temperature gun.
4, temperature gun made from the furnace, remove the used thermocouple, and install new, pause a few minutes, ready for the next measurement. Can not even measure even split, or cause fluctuations in the temperature difference.
Fifth, transportation and storage:
Products to be handled with care during loading and unloading, during transport, must not get wet, the product should be stored at a relative humidity less than 80%, the air flow, causing the product does not contain corrosive harmful gases, FCL placed in dry warehouse
