【熱電対の補償導線 】 熱電対と温調器の接続は補償導線という線で接続しないと精度よく測定できない事を初めて知った。 補償導線は、熱電対の金属と同じか、起電力特性を模倣した材料が使われていて熱電対→補償導線→温調器までの間で、余計な起電力が生じない 皆さん知っていましたか？僕は誤ってIV線で繋ぐところでした汗
The image is a detailed table comparing different types of compensation wires (ESC, ESDC, ESGDC) used with thermocouples for precise temperature measurement. The table lists various specifications such as AC100-240V, AC24V, 50/60Hz, and DC24V, along with current ratings for different models. The post text reveals that the user recently learned about the importance of using compensation wires to maintain measurement accuracy by preventing unwanted electromotive force between the thermocouple and the temperature controller. The user humorously admits they almost used the wrong type of wire (IV line) for the connection, highlighting the educational aspect of the post.
