Insimbi engagqwali izinga lokushisa eliphezulu lohlobo k thermocouple
Incazelo Yomkhiqizo
I-Thermocouple iyisici esivamile sokulinganisa izinga lokushisa. Isimiso se-thermocouple silula. Iguqula ngokuqondile isignali yezinga lokushisa ibe isignali yamandla e-thermoelectromotive futhi iyiguqule ibe izinga lokushisa lendawo elinganisiwe ngethuluzi likagesi. Nakuba isimiso silula, ukulinganisa akulula.
Isimiso Sokusebenza
Amandla kagesi we-thermo akhiqizwa i-thermocouple aqukethe izingxenye ezimbili, amandla okuxhumana kanye namandla kagesi we-thermo.
Amandla Okuxhumana: Ama-conductors ezinto ezimbili ezihlukene anobuningi be-electron obuhlukene. Lapho iziphetho ezimbili zamakhondakta wezinto ezingafani zihlanganiswa ndawonye, lapho kuhlangana khona, kwenzeka ukusakazeka kwama-electron, futhi izinga lokusatshalaliswa kwama-electron lilingana nokuminyana kwama-electron amahhala kanye nezinga lokushisa lomqhubi. Umehluko ongaba khona ube usukwakhiwa ekuxhumekeni, okungukuthi amandla okuxhumana.
Amandla kagesi we-Thermoelectric: Uma izinga lokushisa lazo zombili iziphetho zikakhondatha lihlukile, izinga lokusabalaliswa kwama-electron amahhala kuzo zombili iziphetho zekhondatha lihlukile, okuyinkambu ye-electrostatic phakathi kokuphela kwezinga lokushisa eliphezulu neliphansi. Ngalesi sikhathi, umehluko ohambisanayo ongaba khona ukhiqizwa ku-conductor, okubizwa ngokuthi amandla we-thermoelectric. Lokhu okunamandla kuhlobene kuphela nezakhiwo zomqhubi kanye nezinga lokushisa kuzo zombili iziphetho zomqhubi, futhi akuhlangene nobude bomqhubi, ubukhulu besigaba esiphambanayo, kanye nokusatshalaliswa kwezinga lokushisa ngobude bomqhubi.
Isiphetho esisetshenziswa ngokuqondile ukukala izinga lokushisa lendawo ebizwa ngokuthi isiphetho sokusebenza (esaziwa nangokuthi isiphetho sokulinganisa), kanti esinye sibizwa ngokuthi isiphetho esibandayo (esaziwa nangokuthi isiphetho sesinxephezelo); isiphetho esibandayo sixhunywe kuthuluzi lokubonisa noma ithuluzi elisekelayo, futhi ithuluzi lokubonisa lizobonisa i-thermocouple ekhiqizwe amandla we-thermoelectric.
