Piav kom meej txog qhov ntsuas kub ntawm cov thermocouple

2021-09-29

Thermocoupleyog ib hom kev ntsuas kub, nws yog ib hom kev ntsuas, thermocouple ncaj qha ntsuas kub. Lub voj kaw uas muaj ob lub conductors nrog cov ntaub ntawv sib txawv. Vim yog cov khoom sib txawv, cov khoom siv hluav taws xob sib txawv tsim cov hluav taws xob sib txawv, thiab muaj peev xwm tsim tau tom qab qhov sib npaug ruaj khov. Thaum muaj qhov kub thiab txias ntawm ob qho kawg, qhov tam sim no yuav raug tsim tawm hauv lub voj, thiab lub zog thermoelectromotive yuav raug tsim. Qhov kub sib txawv ntau dua, qhov tam sim no ntau dua. Tom qab ntsuas cov thermoelectromotive quab yuam, qhov ntsuas kub tuaj yeem paub. Hauv kev xyaum, lub thermocouple yog lub zog hloov pauv uas hloov thermal zog rau hauv hluav taws xob hluav taws xob.

Qhov zoo ntawm cov cov thermocouples:cov thermocouplesmuaj qhov ntsuas kub dav thiab muaj kev ua haujlwm ruaj khov; siab ntsuas qhov tseeb, lub thermocouple yog nyob rau hauv kev sib cuag ncaj qha nrog cov khoom ntsuas, thiab tsis cuam tshuam los ntawm qhov nruab nrab nruab nrab; lub sijhawm teb cov lus kub tau nrawm, thiab lub thermocouple nkag siab qhov hloov pauv kub; Qhov ntsuas ntau yog qhov loj, cov thermocouple tuaj yeem ntsuas qhov ntsuas kub tas li los ntawm -40 ~+1600 â ƒ; covthermocouplemuaj kev txhim khu kev qha thiab zoo mechanical zog. Lub neej ntev kev pab cuam thiab yooj yim installation. Cov galvanic ob peb yuav tsum tau tsim los ntawm ob tus neeg xyuas pib (lossis semiconductor) cov khoom siv sib txawv tab sis ua tau raws li qee qhov yuav tsum tau ua rau lub voj voog. Yuav tsum muaj qhov sib txawv ntawm qhov ntsuas kub ntawm qhov ntsuas lub davhlau ya nyob twg thiab qhov ntsuas qhov ntsuas kub ntawm lub thermocouple.

Cov conductors lossis semiconductors A thiab B ntawm ob yam khoom sib txawv yog welded ua ke los tsim lub voj kaw. Thaum muaj qhov kub thiab txias sib txawv ntawm ob lub ntsiab lus txuas 1 thiab 2 ntawm cov conductors A thiab B, ib qho hluav taws xob hluav taws xob yog tsim los ntawm ob, yog li tsim cov tam sim no loj hauv lub voj. Qhov tshwm sim no hu ua cov nyhuv thermoelectric. Thermocouples ua haujlwm siv cov nyhuv no.
