Bakin karfe babban zafin jiki nau'in k thermocouple
Bayanin Samfura
Thermocouple wani abu ne na auna zafin jiki na kowa.Ka'idar thermocouple yana da sauƙi.Yana jujjuya siginar zafin jiki kai tsaye zuwa siginar ƙarfi na thermoelectromotive kuma yana jujjuya shi zuwa zazzabi na matsakaicin aunawa ta kayan aikin lantarki.Kodayake ka'idar tana da sauƙi, ma'auni ba mai sauƙi ba ne.
Ƙa'idar Aiki
Ƙarfin wutar lantarki da thermocouple ke samarwa ya ƙunshi sassa biyu, yuwuwar lamba da ƙarfin wutar lantarki.
Mai yuwuwar Tuntuɓa: Masu gudanarwa na abubuwa daban-daban guda biyu suna da nau'ikan lantarki daban-daban.Lokacin da aka haɗa ƙarshen biyu na madugu na kayan da ba su da kamanni, a mahadar, yaduwar wutar lantarki yana faruwa, kuma adadin watsawar lantarki ya yi daidai da yawa na electrons kyauta da kuma zafin wutar lantarki.Ana samun babban bambanci a haɗin kai, watau yuwuwar lamba.
Thermoelectric m: Lokacin da zafin jiki na duka ƙarshen mai gudanarwa ya bambanta, ƙimar rarrabawar electrons kyauta a duka ƙarshen madubin ya bambanta, wanda shine filin lantarki tsakanin babban zafin jiki da ƙananan ƙarewa.A wannan lokacin, ana haifar da bambance-bambancen da ya dace akan mai gudanarwa, wanda ake kira yuwuwar thermoelectric.Wannan yuwuwar yana da alaƙa ne kawai da kaddarorin mai gudanarwa da zafin jiki a duka ƙarshen mai gudanarwa, kuma ba shi da alaƙa da tsayin madubin, girman ɓangaren giciye, da rarraba zafin jiki tare da tsawon lokacin madugu.
Ƙarshen da ake amfani da shi kai tsaye don auna zafin matsakaici ana kiransa ƙarshen aiki (wanda aka sani da ƙarshen aunawa), ɗayan kuma ana kiransa ƙarshen sanyi (wanda aka sani da ƙarshen ramuwa);an haɗa ƙarshen sanyi zuwa kayan aikin nuni ko kayan tallafi, kuma kayan aikin nuni zai nuna thermocouple ya haifar da yuwuwar thermoelectric.
