Cacisa ngokubanzi iimeko zokulinganisa ubushushu be-thermocouple

Unyango olushushuluhlobo lwento yokubona ubushushu, luhlobo lwesixhobo, i-ubushushu ngokuthe ngqo imilinganiselo yeqondo lobushushu. Isiporo esivaliweyo esenziwe ngabaqhubi ababini ngezinto ezahlukeneyo zokwakheka. Ngenxa yezinto ezahlukeneyo, uxinizelelo lwee-elektroni ezahlukeneyo zivelisa ukusasazeka kwe-elektron, kwaye amandla anokubakho aveliswa emva kokulingana okuzinzileyo. Xa kukho iqondo lobushushu lobushushu kumacala omabini, okwangoku kuya kwenziwa kwilogo, kwaye kuya kwenziwa amandla e-thermoelectromotive. Umkhulu umahluko kumaqondo obushushu, kokukhona ikhoyo ngoku. Emva kokulinganisa amandla e-thermoelectromotive, ixabiso lobushushu linokwaziwa. Ukuziqhelanisa, i-ubushushu sisiguquli samandla esiguqula amandla obushushu abe ngamandla ombane.

Iinzuzo zobugcisa ze-ubushushu:ubushushubanendawo ebanzi yokulinganisa ubushushu kunye nokusebenza okuzinzileyo; ukuchaneka kwemilinganiselo ephezulu, i-ubushushu inxibelelana ngokuthe ngqo kunye nomlinganiso wento, kwaye ayichaphazeleki kwinqanaba eliphakathi; ixesha lokuphendula ngokushushu liyakhawuleza, kwaye i-ubushushu inovakalelo kutshintsho lobushushu; Uluhlu lokulinganisa lukhulu, i-ubushushu inokulinganisa ubushushu ngokuqhubekayo ukusuka -40 ~ + 1600â „ƒ; iubushushuinokusebenza okuthembekileyo kunye namandla afanelekileyo oomatshini. Ubomi benkonzo ende kunye nokufakwa lula. Isibini segalvanic kufuneka senziwe ngezinto ezimbini ze-conductor (okanye i-semiconductor) ezineempawu ezahlukeneyo kodwa zihlangabezana neemfuno ezithile zokwenza iluphu. Kufuneka kubekho umahluko wobushushu phakathi kwetheminali yokulinganisa kunye netheminali yereferensi ye-ubushushu.

Abaqhubi okanye iisemiconductors A kunye no-B bezinto ezimbini ezahlukeneyo badityaniswa ngokudibeneyo ukwenza iluphu evaliweyo. Xa kukho umahluko wobushushu phakathi kwamanqaku amabini okuncamathisela 1 kunye no-2 kubaqhubi A kunye no-B, amandla ombane aveliswayo phakathi kwezi zimbini, ngaloo ndlela esenza umjelo omkhulu okwangoku kwiluphu. Le nto ibizwa ngokuba sisiphumo sombane. I-Unyango olushushus isebenza ngokusebenzisa le miphumo.
