Taw qhia Kho
Hauv cov txheej txheem muaj kev lag luam, qhov ntsuas kub yog qhov ntsuas thiab tswj ib qho tsis tseem ceeb. Nyob hauv kev ntsuas kub, lub thermocouple yog dav siv, nws muaj ib cov qauv yooj yooj yim, tsim tau yooj yim, dav ntsuas ntau, siab precision, me me inertia thiab cov teeb liab tawm los pab txhawb EasTone Far, thiab ntau lwm yam zoo. Tsis tas li ntawd xwb, vim tias cov thermocouple yog ib qho ua kom pom tseeb, ntsuas tsis muaj hwjchim sab nraud, siv kev yoojyim heev, nws yog feem ntau siv los ntsuas cov cua sov, qhov kav dej roj lossis cov dej ua kua thiab cov khoom kub kub [1]
Nws ua haujlwm li cas
Thaum muaj ob hom neeg sib txawv los sis cov cim Semiconductors A thiab B ua lub voj, ob hnub xaus rau ib leeg, tsuav yog ob qhov sib txig sib txig sib txawv, qhov kawg ntawm qhov ntsuas kub T, peb paub ua haujlwm lossis sab sab, Lwm qhov kawg ntawm T0, hu ua dawb kawg (tseem hu ua sab siv) los yog sab txias, lub Circuit Court yuav tsim ib qho kev siv hluav taws xob, qhov kev taw qhia thiab qhov loj ntawm lub tshuab hluav taws xob ntawm cov khoom hluav taws xob thiab qhov kub ntawm ob lub neeg. Qhov tshwm sim no yog hu ua "thermoelectric efficacy", qhov Circuit Court tau tsim los ntawm ob tug neeg hu ua "thermocouple", ob tug neeg hu ua "hot electrode", qhov tshwm sim EMF hu ua "thermoelectromotive Force" [1].
Lub thermo-electromotive quab yuam yog tsim ntawm ob feem ntawm electromotive force, ib feem yog tus hu rau electromotive force ntawm ob hom conductors, qhov thib ib yog qhov kub qhov txawv electromotive force ntawm ib tus neeg xyuas pib.
Thermocouple Voj thermoelectric zog ntawm lub me me, tsuas yog nrog cov lus ntawm lub thermocouple ntawm cov neeg siv khoom siv thiab cov kub ntawm ob cov neeg, thiab thermocouple puab thiab loj muaj tsis muaj dab tsi ua. Thaum ob qho khoom siv tho electrode tho khoom tas, lub thermoelectric quab yuam yog ob qhov sib cuag kub t thiab t0. Ntawm qhov kev ua haujlwm qhov sib txawv [1]. uas yog
Qhov kev sib raug zoo no tau siv dav hauv kev ntsuas kev ntsuas. Vim hais tias qhov txias txias t0 tas thermocouple thermoelectric zog tsuas yog nrog kub kub (ntsuas kawg) hloov hloov, uas yog, ib yam thermal EMF sib haum mus rau ib qho kub. Ntev li ntev tau peb siv txoj kev ntsuas qhov ntsuas ntawm thermoelectromotive quab yuam tau lub hom phiaj ntawm qhov ntsuas kub
