High temperature thermocouple
High temperature thermocouple use and works
Thermocouples used to measure the temperature of the molten steel and high temperature molten metal, is a one time consumptiontype thermocouple. Its working principle is based on the metal thermoelectric effect, the use of a thermocouple at both ends of the temperature difference between the electric measurement of molten steel and high temperature of molten metal.
product specifications and performance comparison
Name | Model indexing | Tolerance | Suitable temperature | Temperature measurement of the upper limit | Response time |
Platinum and rhodium 30 - platinum and rhodium | KB-602P B | ± 5 | 1500-1700 | 1800 | 4 ~ 6s |
Platinum and rhodium - platinum | KS-602P S | ± 5 | 1500-1700 | 1800 | 4 ~ 6s |
Platinum and rhodium Platinum 13% Rhodium - Platinum | KR-602P R | ± 5 | 1500-1700 | 1800 | 4 ~ 6s |
Rhenium - tungsten rhenium 25 | KW-602P W | ± 5 | 1500-1700 | 1800 | 4 ~ 6s |
The structure
The structure of the thermocouple, it is mainly by the temperature puppet heads and paper tubes.Puppet heads, positive and negative dual wire welding in the compensation wire, wear compensating lead wire embedded in the stent, the stent coat a small paper tube, the thermocouple wire to the quartz support and protection. Outermost fitted with a cap, all components of the anti-residue concentrated load dump adhesion to the refractory filler to form a whole, rather than removable, it is a one-time use.
The use of methods
1, according to the measurement object and scope, select the appropriate protection for the length of the paper tube and the applicable temperature gun.
2, the thermocouple mounted on the temperature gun record, and after that make the secondary instrument pointer (or display) back to zero, then the exposure can be measured.
Thermocouple into the molten steel depth 300-400mm is appropriate, when measured not measured on the furnace wall or the scum, so that: fast, stable, accurate, and should be immediately put the gun when the secondary instrument results, fast thermocouple in the molten steel in the soaking time shall not be more than five seconds, or easy to burn the temperature gun.
4, the temperature gun from the furnace, remove the used thermocouple, and install new, pause a few minutes in preparation for the next measurement. Shall not be measured even with the demolition, otherwise caused by temperature fluctuations.
