Cov thermocouple hlau muaj nqisfeem ntau yog cov hlau muaj nqis casing, cov ntaub ntawv insulating, cov ntaub ntawv dipole hlau.

Cov yam ntxwv ntawm cov thermocouples uas muaj hlau zoo nkauj tuaj yeem sau ua cov hauv qab no:

(1) Kev tiv thaiv xeb

(2) kev ruaj khov zoo ntawm lub peev xwm thermal, kev siv mus sij hawm ntev ntawm lub peev xwm thermal drift yog me me;

(3) Qhov txwv sab saud ntawm qhov kub siv yog siab;

(4) Qhov kawg ntawm lub thermocouple armored yog hermetically kaw, tsis muaj roj seem sab hauv

(5) Kev rwb thaiv tsev siab, cov hlau muaj nqis armored thermocouple ntawm chav tsev kub tuaj yeem ncav cuag ntau dua 50MΩ;

(6) Cov lus qhia txog khoom, cov ntaub ntawv tiv thaiv raj tuaj yeem ua tiav raws li tus neeg siv xav tau

(7) Yooj yim rau khoov, yooj ywm zoo, yooj yim rau kev teeb tsa

(8) Tiv taus kev nyuaj siab thiab kev co;

(9) Lub sijhawm teb thermal luv luv; lub neej ua haujlwm ntev
