。">When two points of attachment conductor A and B 1 and 2 between the temperature difference between the two, will produce electromotive force, thus forming a size of the current in the circuit, this phenomenon is called the thermoelectric effect.
Two, work principle:
WRN-240D series More proof thermocouple ，多種不同成份的導(dǎo)體兩端經(jīng)焊接
、">Five, ，形成多個回路，直接測溫端叫工作端
，耐壓性能好；">High mechanical strength, good pressure resistance; ，接線端子端叫冷端
Flexible installation;
；">Large measuring range; ，也稱參比端。">The working principle is that a variety of different components of the conductor ends by welding, forming a plurality of circuit, direct temperature measuring end called the working end, the terminal end is called the cold end, also called the reference terminal. ，就會在回路中產(chǎn)生熱電流
，減小動態(tài)誤差；">The thermal response time, reduce the dynamic error; ，接上顯示儀表，儀表上就會指示出熱電偶所產(chǎn)生的熱電動勢的對應(yīng)溫度值
。">Widely used in petrochemical distillation device. 。">When the temperature difference between the working end and the reference end, will produce thermal current 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.
。">WRN-240D series of <strong> explosion-proof thermocouple more</strong> suitable for the production site are flammable compound, must also measure multiple position or location of multiple measurement.
