Muaj ob hom ntawmcov cov thermocouples, hom hom thiab armored hom.
Cov cov cov thermocouples feem ntau yog tsim los ntawm cov ntsuas cua sov, lub raj thaiv, tiv thaiv lub tes tsho thiab lub thawv sib txuas, thaum cov thermocouple tiv thaiv yog ua ke ntawm cov thermocouple xaim, cov khoom thaiv thiab hlau tiv thaiv lub tes tsho. Kev sib xyaw ua ke tau tsim los ntawm kev ncab. Tab sis cov teeb liab hluav taws xob ntawm lub thermocouple xav tau cov xov hlau tshwj xeeb los xa, cov xov hlau zoo li no hu ua xaim hluav taws xob.Cov thermocouple sib txawv xav tau cov xov tooj sib txawv sib txawv, thiab lawv lub luag haujlwm tseem ceeb yog txhawm rau txuas nrog cov thermocouple kom ua tiav qhov kawg ntawm cov thermocouple kom deb ntawm lub hwj chim, kom qhov ntsuas kub ntawm qhov kawg siv tau ruaj khov.
Cov xov hlau them nyiaj tau muab faib ua ob hom: hom nyiaj them thiab hom txuas ntxiv
Cov tshuaj lom neeg muaj pes tsawg ntawm cov txuas txuas txuas yog tib yam li cov thermocouple tau them, tab sis hauv kev coj ua, txuas txuas txuas tsis tau ua los ntawm cov khoom siv ib yam li thermocouple. Feem ntau, nws tau hloov los ntawm xaim nrog tib lub tshuab hluav taws xob sib xws raws lithermocouple. Kev sib txuas ntawm cov xaim them nyiaj thiab cov thermocouple feem ntau yog qhov tseeb heev. Cov ncej zoo ntawm lub thermocouple yog txuas nrog cov xaim liab ntawm cov xaim them nyiaj, thiab cov ncej tsis zoo txuas nrog cov xim ntxiv.
Feem ntau ntawm cov xov tooj them nyiaj feem ntau yog ua los ntawm tooj liab-npib tsib xee hlau.
Thermocouple yog cov cuab yeej siv kub tshaj plaws hauv kev ntsuas kub. Nws cov yam ntxwv tseem ceeb yog qhov ntsuas kub ntawm qhov dav, kev ua haujlwm ruaj khov, cov qauv yooj yim, cov lus teb zoo, thiab cov hloov pauv hloov pauv tuaj yeem xa 4-20mA cov cim tam sim no nyob deb. , Nws yog qhov yooj yim rau kev tswj tsis siv neeg thiab kev tswj hwm hauv nruab nrab.
Lub hauv paus ntsiab lus ntawmthermocouplekev ntsuas kub yog ua raws cov txiaj ntsig thermoelectric. Kev txuas ob tus neeg sib txawv lossis cov khoom siv hluav taws xob mus rau hauv lub voj kaw, thaum qhov kub ntawm ob qhov kev sib tshuam sib txawv, cov peev xwm thermoelectric yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua thermoelectric effect, tseem hu ua Seebeck effect. Lub peev xwm thermoelectric tsim tawm hauv lub voj kaw yog tsim los ntawm ob hom hluav taws xob muaj peev xwm; qhov sib txawv ntawm qhov muaj peev xwm hluav taws xob thiab qhov muaj peev xwm tiv tauj hluav taws xob.
Txawm hais tias thermal kuj tseem siv dav hauv kev lag luam, nws daim ntawv thov raug txwv vim nws qhov ntsuas kub ntau. Lub hauv paus ntsiab lus ntsuas kub ntawm thermal kuj yog raws li tus nqi tsis kam ntawm tus neeg xyuas pib lossis semiconductor hloov nrog qhov kub thiab txias. yam ntxwv. Nws kuj muaj ntau yam zoo. Nws tseem tuaj yeem xa cov teeb liab hluav taws xob nyob deb. Nws muaj rhiab heev, muaj zog stability, interchangeability thiab raug. Txawm li cas los xij, nws xav tau lub zog hluav taws xob thiab tsis tuaj yeem ntsuas qhov ntsuas kub tam sim ntawd.
Qhov ntsuas kub ntsuas los ntawm cov thermal kuj siv hauv kev lag luam yog qhov tsawg, thiab qhov ntsuas kub tsis tas yuav tsum tau them nyiaj, thiab tus nqi kuj pheej yig.
