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. Lawa mandla ahlobene kuphela nezakhiwo zomqhubi kanye nezinga lokushisa kuzo zombili iziphetho zomqhubi, futhi akuhlangene nobude bomqhubi, usayizi wesigaba esiphambanayo, kanye nokusatshalaliswa kwezinga lokushisa ngobude be-conductor. umqhubi.
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.
