Ama-Thermocouples asetshenziswa ezinhlobonhlobo zezimboni zokulinganisa izinga lokushisa nokulawula. Kodwa-ke, ukunemba nokuthembeka kwe-thermocouple akuxhomekile kuphela ku-sensor ngokwayo, kodwa futhi kukhebula elisetshenziselwa ukuyixhuma entweni yokulinganisa. Izinhlobo ezimbili ezivamile zezintambo ezisetshenziselwa ama-thermocouples izintambo zesinxephezelo nezintambo zokunweba. Nakuba zingabukeka zifana, kunomehluko ohlukile phakathi kwalokhu okubili.
Okokuqala, ake sikhulume ngokuthi ziyini izintambo ezinxephezela i-thermocouple. Amakhebuli anxephezela adizayinelwe ngokuqondile ukuxhuma izinzwa ze-thermocouple ethuluzini lokulinganisa, kunxephezela ukuhluka kwezinga lokushisa ngobude bekhebula. Lezi zintambo zenziwe ngenhlanganisela yezinto ezihlukahlukene ezilingisa izici ze-thermoelectric ze-thermocouple ngokwayo. Lokhu kuqinisekisa ukuthi noma yikuphi ukuguquka kwezinga lokushisa ngobude bekhebula ngeke kuthinte ukunemba kwesilinganiso sokushisa.
Isici esiyinhloko sezintambo zokunxephezela yikhono labo lokugcina izakhiwo ze-thermoelectric ze-thermocouple exhunyiwe. Lokhu kufezwa ngokusebenzisa into enezici ezifanayo ze-thermoelectric ku-thermocouple, iqeda ngokuphumelelayo noma yikuphi ukuhluka kwamandla okushisa okubangelwa izinga lokushisa ngaphezu kobude bekhebula. Ngakho-ke izintambo zokunxephezela zibalulekile ekukalweni kwezinga lokushisa okunembile ezinhlelweni zokusebenza lapho ibanga phakathi kwe-thermocouple nensimbi yokulinganisa lilide noma lapho indawo yezinga lokushisa ingafani khona.
Izintambo zokunweba ze-Thermocouple, ngakolunye uhlangothi, zisetshenziselwa ukunweba ukufinyelela kwe-thermocouple ngaphandle kokuphazamisa ukunemba kwesilinganiso sokushisa. Ngokungafani nezintambo ezinxephezela, izintambo zokunweba azilingisi izici ze-thermoelectric ze-thermocouple. Kunalokho, zenziwa kusukela material efanayo njengobaizintambo ze-thermocouple, ukuqinisekisa ukuthi isignali ye-voltage ekhiqizwa i-thermocouple idluliselwa ngokunembile ebangeni elide. Umsebenzi oyinhloko wezintambo zokunweba ukugcina ubuqotho besignali ye-voltage ekhiqizwe i-thermocouple, eyivumela ukuthi idluliselwe amabanga amade ngaphandle kokulahlekelwa noma ukuhlanekezela. Lokhu kubaluleke kakhulu ezindaweni zezimboni lapho ama-thermocouples angase abekwe ezindaweni zokushisa okuphezulu futhi amathuluzi okulinganisa atholakala kumagumbi okulawula noma ezindaweni ezikude.
Umehluko phakathi kwezintambo zesinxephezelo se-thermocouple namakhebuli esandiso
I-Thermoelectric Properties: Umehluko omkhulu phakathi kwalezi zinhlobo ezimbili zamakhebula izakhiwo zazo ze-thermoelectric. Izintambo ezinxephezelayo ziklanyelwe ukulingisa izici ze-thermoelectric ze-thermocouple, kuyilapho izintambo zokunwetshwa zenziwa ngezinto ezifanayo njengezintambo ze-thermocouple ukuze kugcinwe ubuqotho besignali ye-voltage.
Isinxephezelo Sezinga Lokushisa: Amakhebuli anxephezela aklanyelwe ngokukhethekile ukunxephezela ukuhlukahluka kwezinga lokushisa ngobude bekhebula ukuze kuqinisekiswe izilinganiso ezinembile zezinga lokushisa. Ngokuphambene, izintambo zokunweba azinikezi isinxephezelo sezinga lokushisa futhi zisetshenziselwa ngokuyinhloko ukunweba ububanzi be-thermocouple.
Ukucaciswa Kohlelo Lokusebenza: Izintambo zokunxephezela zibalulekile ezinhlelweni zokusebenza lapho ukuhlukahluka kwezinga lokushisa ngobude bekhebula kungase kuthinte ukunemba kwezilinganiso zokushisa. Ngakolunye uhlangothi, izintambo ezinwetshiwe zisetshenziselwa ukudlulisa amasignali kagesi ebangeni elide ngaphandle kokulahlekelwa noma ukuhlanekezela.
Indlela yokukhetha ikhebula elifanele
Lapho ukhetha ikhebula elifanele lohlelo lwe-thermocouple, izidingo ezithile zesistimu yokulinganisa kufanele zicatshangelwe. Izinto ezifana nebanga eliphakathi kwe-thermocouple nensimbi yokulinganisa, indawo yezinga lokushisa kanye nokunemba kwesilinganiso sokushisa kubalulekile ekunqumeni isidingo sekhebula lesinxephezelo noma sokunwetshwa.
Izintambo zokunxephezela zilungile ezinhlelweni zokusebenza lapho ibanga phakathi kwe-thermocouple nensimbi yokulinganisa likhulu noma lapho indawo yezinga lokushisa ingafani. Lezi zintambo ziqinisekisa ukuthi ukushintsha kwezinga lokushisa ngobude bekhebula akuthinti ukunemba kwesilinganiso sokushisa, ngakho-ke kubalulekile ekulawuleni izinga lokushisa okunembile nokuqapha.
Ngakolunye uhlangothi, izintambo zokunweba zikhethwa ezimeni lapho i-thermocouple idinga ukutholakala kude nethuluzi lokulinganisa. Lezi zintambo zingadlulisela ngokunembile isignali kagesi ekhiqizwe i-thermocouple ebangeni elide, ngaleyo ndlela igcine ubuqotho besilinganiso sokushisa.
Kubalulekile ukuqaphela ukuthi ukusebenzisa uhlobo olungalungile lwekhebula kungaholela ekulinganisweni kwezinga lokushisa okungalungile, okungase kuthinte ikhwalithi nokuphepha kwenqubo eqashweyo. Ngakho-ke kunconywa ukuthi kuxhunyanwe nomhlinzeki onolwazi noma unjiniyela ukuze kuqinisekiswe ukuthi ikhebula elifanele likhethwa kuhlelo oluthile lwe-thermocouple.
Ekugcineni, sinikeza uhla lweizintambo ze-thermocouplengesevisi eyenziwe ngokwezifiso, ngakho-ke zizwe ukhululekile ukuthintana uma udinga!
