吹气式热电偶

　　吹气式热电偶(Thermocouple)

　　吹气式热电偶的结构原理:是在内部的热电偶丝或裸露的工作端与外保护管之间，即由外至内，再由内至外构成气体流动回路。在测温时，注入一定的惰性气体(氮气)以排出或减少高温时还原气体的渗入对热电偶的影响，达到延长热电偶寿命和保证热电偶温度測量的准确目的。

　　分度号：K、S、R、B任选

　　测温范围：0～1100℃，K型;0～1300℃，R、S、B型

　　TC-blowing structure principle in the internal thermocouple wire or bare-side with the work outside the protection of the tube, that is, from outside to inside and then outside to inside the gas flows constitute a loop. Temperature measurements in the When injected a certain degree of inert gas(ammonia )in order to reduce the discharge or reduction when the high temperature gas  to the infiltration of the thermocouple, to extend the reach and life of termocouple teperature measurement thermocouple to ensure the accuracy of purpose

　　EMMT/T:K,S,R,B

　　Temperature:0-1100℃， Type K，0-1300℃， Type R，S，B.
