装配式热电偶通常由感温元件、安装固定装置和接线盒等主要部件组成。
可以直接测量各种生产过程中从0℃到1800℃范围的液体、蒸汽和气体介质以及固体的表面温度，作为测量温度的变送器通常和显示仪表、记录仪表和电子调节器配套使用。型号：B型、S型、K型、E型
测量范围及基本误差限：
[t为感温元件实测温度值（℃）]
Fabricated thermocouples, usually by feeling temperature elements, installation fixtures and junction box and other major parts.
Can be directly measured various production process from 0 ℃ to 1800 ℃ range of liquid, steam and gas medium and solid surface temperature, as measuring temperature transmitter usually and display instrument, recording instruments and supporting the use of electronic regulator. Type: type B, S type, K type, E type
Measurement range and basic error limit:
[t as the feeling temperature elements ℃ temperature (measured)]
