Dab tsi yog thermocouple thiab dab tsi yog nws siv thiab cov ntsiab cai?

Thermocoter yog ib hom ntawm qhov kub thiab txias. Vim tias lawv feem ntau siv hauv kev lag luam tsim khoom, lawv kuj tau hu ua kev muaj cov sensors. Tam sim no, thermocoter yog qhov feem ntau siv kev lag luam muaj kub sensor kub. Txhua tus neeg ua haujlwm nrog kev tsav tsheb kub yuav paub nrog thermocouples. Lawv kuj tuaj yeem raug hu ua thermoounles, thermocouples, thiab lwm yam.

Thermocouples ua haujlwm los ntawm vuam ob qho sib xws me me rau hauv kev kaw Circuit Court. Qhov kub sib txawv tsim lub zog hluav taws xob, ua rau lub voltage nyob rau hauv lub voj voog kom sib txawv nrog kub. Qhov tshwj xeeb logic yog tias ob lub xov hlau tau welded rau hauv lub voj kaw, ib qho yog siv los tshawb xyuas qhov kawg, thiab qhov chaw yog hu ua qhov siv kawg, lossis qhov kawg. Qhov ntsuas kub ntawm kev siv kawg yog qhov tseem ceeb tas li, lossis ntawm chav sov, thaum lub sijhawm ua haujlwm tau siv los kuaj qhov ntsuas kub. Raws li kev ua haujlwm xaus qhov kub hloov pauv, cov hluav taws xob voltage los ntawm kev siv kawg kuj pauv. Qhov kev ua haujlwm xaus kub yuav tau inferred los ntawm cov voltage ntsuas ntawm qhov siv kawg.

Cov lus nug tshwm sim: Yuav ua li cas peb paub kev sib raug zoo ntawm qhov kub thiab voltage? Ob yam me me li cas?

Qhov tsim muaj ntawm cov thermocouple yog raws tus kws tshawb fawb kev tshawb pom ntawm cov nyhuv pom ntawm cov nyhuv.

Raws li cov nyhuv pom kev, ntau cov hlau tau pom tias muaj haum rau kev ntsuas kub. Thiaj li, tus qauv lub rooj, hu ua thermocouple calibration rooj, tau tsim. Cov lus no qhia meej txog kev ntsuas ntsuas ntawm qhov ntsuas kub tshwj xeeb uas siv cov khoom siv tshwj xeeb.

Cov feem ntau muaj xws li s, r, b, k, t, j, thiab c, txhua tus sawv cev ntawm ob hom hlau lossis hlau alloys. Yog li ntawd, thermocoupples ntawm ib qho kev ntsuas tshwj xeeb kuj tseem tuaj yeem hu ua s- type thermocochs lossis c}}}} hom thermocoples.

Thermocoples ntawm kev sib txawv sib txawv sib txawv nyob rau hauv tus nqi vim cov ntaub ntawv siv. Piv txwv li, BSR hom yog feem ntau ua los ntawm cov khoom muaj nuj nqis hlau platinum, ua rau nws kim dua. Lawm, kev ua tau zoo kuj yuav txawv.

Tsis tas li, cov hau kev sib txawv sib txawv. Vim yog kev ua haujlwm sib txawv thiab qhov kub thiab txias, tiv thaiv riam tiv thaiv feem ntau. Yog li ntawd, thermocouces tuaj nyob rau hauv ntau yam ntawm cov duab.
