The use of the dual platinum-rhodium thermocouple

1. Put hurtling platinum rhodium thermocouple on the temperature measuring gun, and secondary instrument pointer ( Or digital display device) Back to zero, then explain the contact is good, can perform measurements. 2. Hurtling thermocouple pull out the depth of the molten steel with 300-400 - mm advisable, measurement without the furnace wall or pulp are done: fast, steady, accurate, when secondary instrument lose consequences, should immediately carry guns, hurtling thermocouple immersion time in molten steel shall not exceed 5 seconds, otherwise easy to burn temperature measuring gun. 3. According to the measured object and domain, select the appropriate maintenance paper tube length and suitable temperature measuring gun. 4. Temperature measuring gun from the furnace is raised, the use of a dual platinum rhodium thermocouple, and put on the new progress in a few minutes, prepare the next measurement. Not even measure even split, or forming temperature difference.
