Description：

、產(chǎn)品概述：">Productoverview:
WRNG-440T series Thermocouple cracking furnace

，使之緊貼于裂解爐管內(nèi)側(cè)，同時(shí)又不影響物料流動(dòng)

。">The protective tube adopts special structure, so close to the cracking furnace tube inside, and does not affect the material flow.

。">Suitable for measurement and control of temperature in the production process of ethylene cracking furnace.
Two, work principle:
WRNG-440T series Thermocouple cracking furnace 、形成回路

，直接測(cè)溫端叫測(cè)量端，接線端子端叫參比端

。">Two different components of the conductor ends by welding, forming a loop direct temperature measuring end call measurement end, terminal end call reference end. ，就會(huì)在回路中產(chǎn)生熱電勢(shì)，接上顯示儀表

，儀表上就指示出熱電偶所產(chǎn)生的熱電動(dòng)勢(shì)的對(duì)應(yīng)溫度值

。">When there is temperature difference between the measuring terminal and a reference terminal, will produce thermal emf in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the.
