The working principle of fast thermocouple

Fast working principle of thermocouple rapid temperature measuring thermocouple is used to measure the temperature of molten steel and molten metal at low temperature, is a one-time cost thermocouple. Hurtling thermocouple its task principle is according to the metal thermoelectric effect, application of what is happening on both ends of the thermocouple temperature electric heating measurement of molten steel and high temperature molten metal. The structure of the thermocouple, it is important to consist of WenOu measuring head and big paper tube. I first important have positive and negative I wire welding on the compensation wire, compensation conductor wearing embedded on the bracket, bracket coat have small paper tube, accidentally to quartz support and maintenance. Outside with slag cap, all components in the concentrated load NiTou and all of the refractory filler sticky decomposition and and no assembly, reason for one-time use.

the product, transportation and storage to handle with care when loading and unloading, transport process, shall not be affected with damp be affected with damp, the product should be stored in temperature is not more than 80%, the air circulation, the product does not contain lead harmless gas corrosion, the whole case is put in the warehouse of dull. Second, according to the measured object and domain, select the appropriate maintenance paper tube length and suitable temperature measuring gun. Three, put hurtling 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. Four, 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. Five, the temperature measuring gun from the furnace is raised, removed using a thermocouple, and put on the new progress in a few minutes, prepare the next measurement. Not even measure even split, or forming temperature difference.
