Izizathu zohlelo lokusebenza lwe-thermocouple olungafanelekile

Ngokusho kwe-i-i-i-insimbiinombolo yenkomba B, S, K, E namanye amazinga okushisa we-i-i-i-insimbi ahambelana nenani le-millivolt (MV), ezingeni lokushisa elifanayo, inani lenombolo elakhiwe nge-millivolt (MV) B linombolo encane kunazo zonke, inombolo yenkomba ye-S incane kunazo zonke, i-K index inombolo inkulu, inombolo ye-E inombolo enkulu kunazo zonke, landela lesi simiso ukwahlulela.

Ama-i-i-i-insimbis afaneleka ngokuhlaziywa nokuqinisekiswa awafaneleki ukusetshenziswa. Lokhu okwenzekayo akwaziwa futhi akuvusanga ukunaka kwabantu. Isenzakalo esingafanelekile ekusetshenzisweni kwe-i-i-i-insimbi ebangele ukuqinisekiswa ikakhulukazi ngenxa yethonya le-inhomogeneity yocingo lwe-i-i-i-insimbi, iphutha le-shunt le-i-i-i-insimbi ye-armored kanye nokusetshenziswa okungalungile kwe-i-i-i-insimbi. Umhleli wenethiwekhi yokufunda kagesi uchaza imfihlakalo kulesi sihloko.

Umthelela we-inhomogeneity yentambo ye-i-i-i-insimbi â‘ Into ye-i-i-i-insimbiakuhambisani. Lapho i-i-i-i-insimbi ihlolwe egumbini lokulinganisa, ngokuya ngezidingo zemithethonqubo, ukujula kokufakwa esithandweni sokuqinisekisa i-i-i-i-insimbi kungama-300mm. Ngakho-ke, umphumela wokuqinisekisa we-i-i-i-insimbi ngayinye ungakhombisa noma ubonise ikakhulukazi ucingo lwama-300nm olude kusukela ekugcineni kwesilinganiso. Ukuziphatha kwe-thermoelectric. Kodwa-ke, lapho ubude be-i-i-i-insimbi bude, iningi lezintambo lisendaweni eshisa kakhulu ngesikhathi sokusetshenziswa. Uma ucingo lwe-i-i-i-insimbi lungafani futhi lusendaweni ene-gradient yokushisa, ingxenye yalo izokhiqiza amandla we-thermoelectromotive. Amandla we-electromotive abizwa ngokuthi amandla we-parasitic, futhi iphutha elibangelwa amandla we-parasitic libizwa ngokuthi iphutha elifanayo.

Ubungqingili bokuthii-i-i-insimbiucingo ngemuva kokusetshenziswa. Mayelana nokwenziwe okushai-i-i-insimbi, noma ngabe ukusebenza okuhlukile kuhlangabezana nezidingo, ukucubungula okuphindaphindiwe nokugoba kuzobangela i-i-i-i-insimbi ukuthi ikhiqize ukuhlanekezela kokucubungula, futhi izolahlekelwa ukufana kwayo. Ngaphezu kwalokho, i-i-i-i-insimbi izolahlekelwa i-homogeneity yayo uma isetshenziswa isikhathi eside ngaphansi kokushisa okuphezulu. Ukuwohloka kwamandla e-electromotive ashisayo kubangele ushintsho. Uma ingxenye yokuwohloka isendaweni enezinga lokushisa, izophinda ikhiqize amandla kagesi oyisinanakazana abekwe ngaphezulu kwengqikithi yamandla e-thermoelectromotive futhi yethule iphutha lokulinganisa.
