Cov teeb meem twg yuav tsum tau them nyiaj rau hauv daim ntawv thov ntawm thermocouples
Tso lus
Ob tug nais ntsej muag ntawm cov khoom sib txawv (hu ua Thermocouple xaim lossis thermoelectrode) tau txuas nrog ob kawg los ua lub voj. Thaum qhov ntsuas kub ntawm lub hlws ris yog txawv, kev quab yuam hluav taws xob yuav tsim tawm hauv lub voj. Qhov tshwm sim no hu ua cov nyhuv thermoelectric, thiab lub zog hluav taws xob no hu ua lub peev xwm thermoelectric. Thermocouples siv lub ntsiab cai no los ntsuas qhov kub. Ntawm lawv, qhov kawg ncaj qha siv los ntsuas qhov ntsuas kub ntawm lub nruab nrab yog hu ua kev ntsuas qhov kawg (tseem hu ua qhov kawg); Qhov kawg xaus yog txuas nrog rau cov zaub nto lossis cov khoom sib txuam, thiab cov chaw ua kom pom cov nplaim thermoelectric los ntawm thermocouple.
Ib lub thermocouple yog qhov tseeb lub zog hloov pauv uas converts thermal zog rau hauv lub zog hluav taws xob thiab siv cov thermoelectric muaj peev xwm ntsuas kub. Hais txog lub peev xwm thermoelectric muaj peev xwm ntawm thermocouple, cov teeb meem nram qab no yuav tsum tau sau tseg:
(1) Lub peev xwm thermoelectric yog qhov sib txawv ntawm qhov ntsuas kub ntawm ob qho kawg ntawm qhov kub ntawm qhov sib txawv ntawm cov thermocrouple;
(2) Thaum cov khoom siv ntawm Thermocouple yog uniform yog uniform
(3) Thaum cov ntaub ntawv muaj pes tsawg leeg ntawm ob xaim hluav taws xob yog txiav txim siab, qhov loj me ntawm cov thermocoupricel yog tsuas muaj feem cuam tshuam rau qhov kub ntawm lub thermocouple; Yog hais tias qhov ntsuas kub ntawm qhov txias txias ntawm thermocouple tseem tas mus li, tom qab ntawd lub peev xwm thermoellets yog tsuas yog ib qho nuj nqi ntawm kev ua haujlwm thaum xaus.
