Fast Thermocouple Types R/S/B used on Thermometer temperature gun to measure casting metal temperature
 
The fast response thermocouple is used on the thermometer temperature gun for measuring the temperature of molten steel and high temperature molten metal. It is disposable expendable thermocouple.
The characteristics of this thermocouple is high accuracy, rapid reaction, light structure and easy to use. 
Name Type Model The best Max Accuracy Wire diameter(mm)
PtRh10%/Pt S KS-602/604 1500-1700 1750 ≤±5 0.05
PtRh13%/Pt R KR-602/604 1400-1600 1750 ≤±5 0.05
PtRh30%/PtRh6% B KB-602/604 1400-1600 1800 ≤±5 0.05
WRe5%-WRe26% C KC(KW5/26)602/604 1500-1700 1800 ≤±7 0.08
WRe3%-WRe25% D KD(KW3/25)602/604 1500-1700 1800 ≤±7 0.08
 
 
The length of the protecting tube:300mm, 500mm, 600mm, 800mm, 900mm, 1000mm, 1200mm etc ,length can also be customized by customers.

Method of Use Fast Thermocouple Types R/S/B
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.
