ThermocoupleThermocouple

、產(chǎn)品概述：" style="background: transparent">Productoverview:
WRN series Petrochemical special thermocouple

，可以直接測量－200℃－1600℃范圍內(nèi)液體

、蒸汽和氣體介質(zhì)以及固體表面測溫

。" style="background: transparent">Professional for the petrochemical sector design, can directly measure the temperature range of 200 DEG C 1600 liquid, steam and gas and solid surface temperature.
、工作原理：">Two, work principle:
WRN series Petrochemical special thermocouple ，當(dāng)接合點的溫度不同時

，在回路中就會產(chǎn)生電動勢

，這種現(xiàn)象稱為熱電效應(yīng)，而這種電動勢稱為熱電勢

。">Two different components of the conductor (called thermocouple wire or thermal electrode) is connected to the two ends of the synthetic circuit, when the junction temperature at the same time, in the loop will produce electromotive force, this phenomenon is called the thermoelectric effect, and this is called thermal electromotive force emf.
，其中，直接用作測量介質(zhì)溫度的一端叫做工作端（也稱為測量端）

，另一端叫做冷端（也稱為補償端）

；冷端與顯示儀表或配套儀表連接，顯示儀表會指出熱電偶所產(chǎn)生的熱電勢

。" style="background: transparent">A thermocouple is used to measure temperature of this principle, which is directly used for measuring the temperature of a medium called the working end (also known as the measuring end), the other end is called the cold end (also known as the end of the cold end compensation); and display instrument or meter display instrument connection, will point out that the thermoelectric potential generated by thermocouple.

、應(yīng)用場合：">Three, application:

WRN series Petrochemical special thermocouple 、蒸汽和氣體介質(zhì)以及固體表面測溫
