Izizathu zesicelo esingafanelekanga se-thermocouple

Ngokutsho kweubushushuinombolo yesalathisi B, S, K, E kunye nezinye iqondo lobushushu le-ubushushu elihambelana nexabiso le-millivolt (MV), kwiqondo lobushushu elifanayo, ixabiso le-millivolt elenziwe (MV) B inani lesalathisi lincinci , inani lesalathisi se-S lincinci, i-K index inani likhulu, inani lesalathiso esingu-E lelona likhulu, landela lo mgaqo ukuze ugwebe.

Ii-ubushushus ezikulungeleyo ukuhlalutya kunye nokuqinisekisa azikulungelanga ukusetyenziswa. Le nto ayaziwa kwaye ayivusanga ingqalelo yabantu. Into engafanelekanga ekusetyenzisweni kwe-ubushushu ebangele ukungqinisisa ikakhulu kungenxa yempembelelo ye-inhomogeneity yocingo lwe-ubushushu, impazamo ye-shunt ye-ubushushu ye-armored kunye nokusetyenziswa gwenxa kwe-ubushushu. Umhleli wenethiwekhi yokufunda umbane ucacisa imfihlakalo kweli nqaku.

Impembelelo ye-inhomogeneity yocingo lwe-ubushushu â‘ Imathiriyeli yeubushushuayifani. Xa i-ubushushu ihlolwe kwigumbi lokulinganisa, ngokweemfuno zemimiselo, ubunzulu bokufakwa kwi-furnace yokuqinisekisa i-ubushushu yi-300mm. Ke ngoko, iziphumo zokuqinisekiswa kwe-ubushushu nganye zinokubonisa kuphela okanye ubukhulu becala i-300nm yocingo olude lwesibini ukusuka kwisiphelo somlinganiso. Ukuziphatha kwe-thermoelectric. Nangona kunjalo, xa ubude be-ubushushu bude, ezininzi zeengcingo zikwindawo yokushisa ephezulu ngexesha lokusetyenziswa. Ukuba ucingo lwe-ubushushu lu-inhomogeneous kwaye lukwindawo eneqondo lokushisa, ngoko inxalenye yalo iya kuvelisa amandla e-thermoelectromotive. La mandla e-electromotive abizwa ngokuba yi-parasitic potential, kwaye impazamo ebangelwa yi-parasitic enokubakho ibizwa ngokuba yimpazamo ye-homogeneous.

Ubume be-inhomogeneityubushushuucingo emva kokusetyenziswa. Ngokubhekisele kwinto esandula ukwenziwaubushushu, nokuba ukusebenza okungafaniyo kuyahlangabezana neemfuno, ukulungiswa okuphindaphindiweyo kunye nokugoba kuya kubangela ukuba i-ubushushu ivelise ukuphazamiseka kokuqhubekeka, kwaye iya kuphulukana nobungqingili bayo. Ngapha koko, i-ubushushu iya kuphulukana ne-homogeneity yayo xa isetyenziswa ixesha elide phantsi kobushushu obuphezulu. Ukonakala kwamandla ombane oshushu kubangele utshintsho. Xa indawo yokonakala ikwindawo kwindawo enobushushu bomgangatho, iya kuthi kwakhona ivelise amandla okubamba amandla embane kumandla onke e-thermoelectromotive kwaye ibonise impazamo yokulinganisa.
