普通偶头热电偶 刚玉热电偶

一、产品简介   productintroduction

       wr系列工业用装配式热电偶作为测量温度的传感器，通常和显示仪表、记录仪表和电子调节器配套使用。它可以直接测量各种生产过程中从0c~1800℃范围内的液体、蒸汽和气体介质以及固体的表面温度。

       wrseries of industrial assembly type thermocouple as the measurementof the temperature sensor, usually and display instrument,recording instrument and electronic supporting the use ofregulator. it can directly measure the various production processfrom 0c~1800℃range liquid, steam and gas andsolid medium surface temperature.

       根据国家规定，我公司生产符合iec分度号的铂铑30-铂铑6、铂铑10-铂、镍铬-镍硅、镍铬-铜镍、铜-铜镍、铁-铜镍等形式。

       accordingto the provisions of the state, our company in line with the iecinternational standard index number platinum and rhodium30-platinumand rhodium6、platinum and rhodium10-platinum、nickel chromium - nickel silicon,nickel - chromium, copper copper - nickel, iron copper - nickelform.

二、工作原理   workingprinciple

       热电偶的工作原理是：两种不同成分的导体两端经焊接、形式回路，直接测温端叫测量端，接线端子端叫参比端。当测量端和参比端存在温差时，就会在回路时产生热电流，接上显示仪表，仪表上就指示出热电偶所产生的热电动势的对应温度值。

       热电偶的热电动势将随着测量端温度升高而增长，热电动势的大小只和热电偶导体材质以及两端温差有关，和热电极的长度、直径无关。

       装配式热电偶主要由接线盒、保护管、绝缘套管、接线端子、热电极组成基本结构，并配以各种安装固定装置组成（见下图）。

       thermocoupleassembly is mainly composed of a junction box, protection tube,insulating sleeve, terminals, power is the basic structure, andwith a variety of mounting and fixing device (seebelow).
