Dab tsi yog thermocouple?

Lub thermocouple, tseem hu ua "thermoelectrical thermometer", yog ib qho khoom siv hluav taws xob uas muaj ob qhov sib txawv ntawm cov hluav taws xob hluav taws xob sib txuas ua ib qho hluav taws xob sib txuas. Lub thermocouple ua rau qhov ntsuas kub ntawm qhov ntsuas kub raws li qhov tshwm sim ntawm Seebeck effect, thiab qhov hluav taws xob no tuaj yeem txhais los ntsuas qhov ntsuas kub. Thermocouples yog dav siv los ua qhov ntsuas kub.

Q: Yuav ua li cas yog thermocouple txuas nrog PLC?

A: Muaj ob txoj hauv kev los txuas cov thermocouples thiab RTDs rau PLC. Thawj txoj kev yog txuas lawv mus rau lub transmitter uas txuas mus rau lub PLC thiab lub log input module, los yog thib ob txoj kev, qhov twg ib co PLCs muaj ib tug kub sensor module, yog li cov sensors txuas ncaj qha rau lawv.

Q: Vim li cas thermocouple zoo rau qhov kub thiab txias?

A: Lawv muaj qhov tsim nyog siab thiab cov kab tawm EMF cov zis thiab muab qhov tseeb zoo rau kev ntsuas kub siab txog 4170 degree F (2300 degree).

Q: Qhov txawv ntawm Chav Kawm 1 thiab Chav Kawm 2 thermocouple yog dab tsi?

A: Chav Kawm 2 muaj qhov yuam kev loj tshaj plaws nrog rau chav kawm 1 feem ntau (tab sis tsis yog tshwj xeeb) kwv yees li ib nrab ntawm Chav Kawm 2. Chav Kawm 1 zoo ib yam li ANSI tshwj xeeb txwv, nrog rau ANSI tshwj xeeb txwv muaj me ntsis nruj dua chav kawm 1 ntawm qee qhov kub. .

Q: Lub thermocouple twg yog qhov tseeb dua?

A: Qhov tseeb: Hom T thermocouples muaj qhov nruj tshaj plaws ntawm txhua lub hauv paus hlau thermocouples ntawm ± 1C lossis ± 0.75% qhov twg yog qhov ntau dua, tab sis qhov kub ntawm qhov tsuas yog -40 ~ 35{{7 }}C.
