Thermocouple lug nyob rau hauv thiaj li yuav xyuas kom meej tias lub thermocouple yog txhim khu kev qha thiab ruaj khov ua hauj lwm, nws cov qauv yog raws li nram no:
1, ob thermoelectric thermocouple muaj li ntawm vuam yuav tsum tau tsau;
2, nruab nrab ntawm ob tshav kub txhua lwm yam yuav tsum zoo insulated los mus tiv thaiv luv luv circuits;
3, compensating cables txuas rau cov dawb kawg ntawm lub thermocouple yuav yooj yim thiab txhim khu kev qha;
4, kev tiv thaiv lub tes tsho yuav tsum xyuas kom meej tag nrho tshav kub thiab teeb meem xov xwm kev rho tawm.
Ua hauj lwm hauv paus ntsiab lus
1, thermocouple EMF yog lub thermocouple hlws ris kub ntawm ob hnub ntawm lub differential ntawm ib tug muaj nuj nqi, es tsis txhob ntawm thermocouple txias kawg nrog kawg muaj nuj nqi ntawm kub txawv rau ob hnub;
Loj ntawm 2, generated los ntawm cov thermocouple thermoelectric lub hwj chim, thaum lub thermocouple ntaub ntawv yog uniform, thiab muaj tsis muaj dab tsi ua li cas nrog qhov ntev thiab txoj kab uas hla ntawm lub thermocouple, thermocouple ntaub ntawv hais txog cov muaj pes tsawg leeg thiab qhov kub thiab txias sib txawv nruab nrab ntawm tus xaus;
3, thaum ob tug ntawm cov thermocouple thermocouple hlau cov ntaub ntawv uas muaj pes tsawg leeg yog txiav txim, luaj li cas ntawm cov thermocouple EMF, kev txhawj xeeb tsuas nrog lub thermocouple kub sib txawv; yog hais tias tus thermocouple txias hlws ris kub yuav tsum tau khaws cia, cov ua hauj lwm kub ntawm lub thermocouple thermoelectric hwj chim tsuas yog ib-muaj nuj nqis muaj nuj nqi. Lub ob conductors los yog semiconductor ib tug thiab b ntawm ntaub ntawv sib txawv welded ua ke tsim tau ib lub voj kaw, raws li qhia nyob rau hauv daim duab. Thaum tus neeg xyuas pib ib tug thiab b ob Symptoms cov ntsiab lus 1 thiab 2 thaum muaj ib tug kub qhov sib txawv, ntawm EMF thiab tam sim no nyob rau hauv lub Circuit Court txoj kev ib tug loj. Thermocouple yog siv no cov nyhuv ua hauj lwm.
