I-K-type thermocouple iyinzwa yokushisa evame ukusetshenziswa, futhi impahla yayo ikakhulukazi yakhiwe izintambo ezimbili zensimbi ezihlukene. Izintambo ezimbili zensimbi ngokuvamile ziyi-nickel (Ni) ne-chromium (Cr), eyaziwa nangokuthi i-nickel-chromium (NiCr) kanye ne-nickel-aluminium (NiAl) thermocouples.
Umgomo wokusebenza weK-uhlobo lwe-thermocoupleisekelwe kumphumela we-thermoelectric, okungukuthi, lapho amalunga ezintambo ezimbili zensimbi ezihlukene emazingeni okushisa ahlukene, kuzokwenziwa amandla e-electromotive. Ubukhulu bala mandla e-electromotive bulingana nokuhluka kwezinga lokushisa kwelunga, ngakho inani lokushisa linganqunywa ngokulinganisa ubukhulu bamandla e-electromotive.
Izinzuzo zohlobo lwe-Kama-thermocoupleszihlanganisa ububanzi bokulinganisa obubanzi, ukunemba okuphezulu, ukuzinza okuhle, isikhathi sokuphendula esisheshayo, nokumelana nokugqwala okuqinile. Ngesikhathi esifanayo, ingasetshenziswa futhi ezimweni ezihlukahlukene ezinzima zemvelo, njengezinga lokushisa eliphezulu, i-oxidation, ukugqwala nezinye izindawo. Ngakho-ke, ama-thermocouples ohlobo lwe-K asetshenziswa kakhulu embonini, amandla, ukuvikelwa kwemvelo, ezokwelapha nakweminye imikhakha.
Lapho kukhiqizwa ama-thermocouples ohlobo lwe-K, izinto zensimbi ezifanele nezinqubo kudingeka zikhethwe ukuze kuqinisekiswe ukusebenza kwazo nokuzinza. Ngokuvamile, izintambo ze-nickel-chromium kanye ne-nickel-aluminium zinezidingo zokuhlanzeka okuphezulu futhi zidinga izinqubo ezikhethekile zokuncibilika nokucutshungulwa. Ngesikhathi esifanayo, kudinga ukunakwa ekuqinisekiseni ikhwalithi nokuzinza kwamalunga ngesikhathi sokukhiqiza ukugwema izinkinga ezifana nokukhukhuleka kwezinga lokushisa noma ukwehluleka.
Ngokuvamile, ama-thermocouples ohlobo lwe-K enziwa ikakhulukazi ngezintambo zensimbi ze-nickel ne-chromium. Ukusebenza kwawo kuzinzile futhi kuthembekile, futhi asetshenziswa kakhulu emikhakheni ehlukahlukene yokulinganisa izinga lokushisa. Kuzinhlelo zokusebenza ezingokoqobo, kuyadingeka ukukhetha imodeli efanelekile ye-thermocouple kanye nokucaciswa ngokuya ngendawo ethile yokusetshenziswa nezidingo, futhi kwenziwe ukufakwa nokulungiswa okulungile ukuze kuqinisekiswe ukunemba kwayo nempilo yesevisi.
Okungenhla yisingeniso esifushane se-K-type thermocouple material. Ngethemba ukuthi ingakusiza uqonde kangcono isimiso sokusebenza nokusebenzisa le nzwa yezinga lokushisa. Uma udinga ulwazi oluningiliziwe noma izixhumanisi zesithombe ukuze uqonde kangcono impahla kanye nokwakheka kwama-thermocouples ohlobo lwe-K, sicela ukhululekengibuzeumbuzo futhi ngizokunikeza wona ngokushesha ngangokunokwenzeka.
