一、產品簡介   Product introduction

       WR系列工業用S型鉑銠熱電偶作為測量溫度的傳感器，通常和顯示儀表、記錄儀表和電子調節器配套使用。它可以直接測量各種生產過程中從0C~1800℃范圍內的液體、蒸汽和氣體介質以及固體的表面溫度。

       WR series of industrial assembly type thermocouple as the measurement of the temperature sensor, Usually and display instrument, Recording instrument and electronic supporting the use of regulator. It can directly measure the various production process from 0C~1800℃range Liquid, steam and gas and solid medium surface temperature.

       根據規定，我公司生產符合IEC國際標準分度號的鉑銠30-鉑銠6、鉑銠10-鉑、鎳鉻-鎳硅、鎳鉻-銅鎳、銅-銅鎳、鐵-銅鎳等形式。

       According to the provisions of the state, Our company in line with the IEC international standard index number Platinum and rhodium30-Platinum and rhodium6、Platinum and rhodium10- Platinum、Nickel chromium - nickel silicon, Nickel - chromium, Copper copper - nickel, Iron copper - Nickel Form.

二、工作原理   Working principle

      S型鉑銠熱電偶的工作原理是：兩種不同成分的導體兩端經焊接、形式回路，直接測溫端叫測量端，接線端子端叫參比端。當測量端和參比端存在溫差時，就會在回路時產生熱電流，接上顯示儀表，儀表上就指示出熱電偶所產生的熱電動勢的對應溫度值。

       Thermocouple Working principle. Two different components of the conductor ends by welding, form loop, Direct temperature measuring end called the measuring end, The terminal end is called the reference terminal. When the measuring end and the reference end Temperature difference, Will be in the loop Thermal current, Connected to display instrument, The instrument will indicate the thermocouple Thermal electromotive force Corresponding temperature.

       熱電動勢將隨著測量端溫度升高而增長，熱電動勢的大小只和熱電偶導體材質以及兩端溫差有關，和熱電極的長度、直徑無關。

       The thermocouple electromotive force with The measuring end temperature and growth, The size of thermal emf Only and thermocouple conductor material And the temperature difference between the two ends of the relevant, And the power electrode length, diameter.

       裝配式熱電偶主要由接線盒、保護管、絕緣套管、接線端子、熱電極組成基本結構，并配以各種安裝固定裝置組成（見下圖）。

       Thermocouple assembly is mainly composed of a junction box, protection tube, insulating sleeve, terminals, power is the basic structure, And with a variety of mounting and fixing device (see below).
