I-Thermocoumples isetshenziswa engxenyeni ehlukahlukene yezimboni zokulinganisa okushisa nokulawula. Kodwa-ke, ukunemba nokwethenjwa kwe-thermocouple kuxhomekeke hhayi kuzinzwa uqobo kuphela, kodwa futhi kwintambo esetshenziselwe ukuyixhuma kwithuluzi lokulinganisa. Izinhlobo ezimbili ezivamile zezintambo ezisetshenziselwa ama-thermocoumpules kuyizintambo zesinxephezelo kanye nezintambo zokunwetshwa. Ngenkathi zingabonakala zifana, kunomehluko ohlukile phakathi kwalokhu okubili.
Okokuqala ake sixoxe ngokuthi yikuphi ukunxephezela izintambo ze-thermocouple. Izintambo zokunxephezela zenzelwe ukuxhuma imizwa ye-thermocouple kwithuluzi lokulinganisa, inxephezela ukuhluka kokushisa ngaphezulu kobude bekhebula. Lezi zintambo zenziwa ngokuhlanganiswa kwezinto ezihlukile ezilingisa izakhiwo ze-thermocectric zodwa. Lokhu kuqinisekisa ukuthi noma yikuphi ukushintsha izinga lokushisa kushintsha ubude bekhebula ngeke kuthinte ukunemba kwesilinganiso sokushisa.
Isici esiyinhloko sezintambo zokunxephezela yikhono labo lokugcina izakhiwo ze-thermoelectric ze-thermocouple exhunyiwe. Lokhu kutholakala ngokusebenzisa impahla enezinto ezifanayo ze-thermoelectric ku-thermocouple, ukuqeda ngempumelelo noma yikuphi ukuhlukahluka kwamandla kagesi okubangelwa kokushisa ngaphezulu kwekhebula. Ngakho-ke ukunxephezela izintambo ngakho-ke kubalulekile ekulinganiseni izinga lokushisa kuzinhlelo zokusebenza lapho ibanga phakathi kwe-thermocouple kanye nethuluzi lokulinganisa lingesikhathi eside noma lapho indawo yokushisa ingafani.
I-Thermocouple izintambo zesakhiwo, ngakolunye uhlangothi, kusetshenziselwa ukwelula ukufinyelela kwe-thermocouple ngaphandle kokuyekethisa ukunemba kwesilinganiso sokushisa. Ngokungafani nezintambo zokunxephezela, izintambo zokunwebeka azilingisi izakhiwo ze-thermoelectric ze-thermocouple. Esikhundleni salokho, zenziwa ngento efanayo neizintambo ze-thermocouple, Ukuqinisekisa ukuthi isiginali ye-voltage ekhiqizwe yi-thermocouple idluliselwa ngokunembile amabanga amade. Umsebenzi oyinhloko wezintambo zokunwetshwa ukugcina ubuqotho besiginali ye-voltage ekhiqizwe yi-thermocouple, ukuvumela ukuthi kudluliselwe ngaphezulu kwamabanga amade ngaphandle kokulahlekelwa noma ukuhlanekezela. Lokhu kubaluleke kakhulu ezindaweni zezimboni lapho ama-thermocoumpules angatholakala ezindaweni eziphakeme zokushisa kanye nezinsimbi zokulinganisa zitholakala emakamelweni okulawula noma ezindaweni ezikude.
Umehluko phakathi kwezintambo zesinxephezelo se-thermocouple kanye nezintambo zokunwetshwa
I-Thermoelectric Properties: Umehluko omkhulu phakathi kwalezi zinhlobo ezimbili zezintambo yizakhiwo zazo ze-thermoelectric. Izintambo zokunxephezela zenzelwe ukulingisa izakhiwo ze-thermoelectric ze-thermocouple, ngenkathi zenziwa amakhekhe ezinto ezifanayo njengezintambo ze-thermocouple ukuze zigcine ubuqotho besiginali ye-voltage.
Isinxephezelo sokushisa: Izintambo zokunxephezela zenzelwe ngokukhethekile ukunxephezela ukuhlukahluka kwezinga lokushisa kanye nobude bekhebula ukuqinisekisa izilinganiso zokushisa ezinembile. Ngokuphambene, izintambo zokunwebeka azinikezi isinxephezelo sokushisa futhi ngokuyinhloko zisetshenziselwa ukwandisa ububanzi be-thermocouple.
Okunye Okucacisiwe: Izintambo zokunxephezela zibalulekile ezicelo zokuhluka lapho ukuhlukahluka kokushisa kanye nobude bekhebula kungakuthinta ukunemba kwezilinganiso zokushisa. Izintambo zokunwetshwa, ngakolunye uhlangothi, zisetshenziselwa ukudlulisa amasiginali kagesi amabanga amade ngaphandle kokulahlekelwa noma ukuhlanekezela.
Ungayikhetha kanjani ikhebula elifanele
Lapho ukhetha ikhebula elifanele lohlelo lokusebenza lwe-thermocouple, kufanele kubhekwe nezidingo ezithile zohlelo lokulinganisa. Izici ezifana nebanga phakathi kwe-thermocouple kanye nethuluzi lokulinganisa, indawo yokushisa kanye nokunemba kwesilinganiso sokushisa kubalulekile ekunqumeni isidingo sekhebula elinxephezelayo noma ukunwetshwa.
Izintambo zokunxephezela zilungele izinhlelo zokusebenza lapho ibanga phakathi kwe-thermocouple kanye nethuluzi lokulinganisa likhulu noma lapho imvelo yokushisa ingafani. Lawa makhebuli aqinisekisa ukuthi izinga lokushisa lishintsha ngobude bekhebula alithinti ukunemba kwesilinganiso sokushisa, ngakho-ke kubalulekile ekuphatheni okunembile kokushisa nokuqapha.
Ngakolunye uhlangothi, izintambo zokunwebeka zikhethwa ezimweni lapho i-thermocouple idinga ukutholakala kude nensimbi yokulinganisa. Lezi zintambo zingadlulisela ngokunembile isiginali ye-voltage ekhiqizwe yi-thermocouple ngaphezulu kwamabanga amade, ngaleyo ndlela silondoloze ubuqotho besilinganiso sokushisa.
Kubalulekile ukuqaphela ukuthi ukusebenzisa uhlobo olungalungile lwekhebula kungaholela ekulinganisweni kokushisa okungalungile, okungathinta ikhwalithi nokuphepha kwenqubo kubhekwe. Ngakho-ke kunconywa ukuthi kuboniswanelwe umphakeli noma unjiniyela onolwazi ukuqinisekisa ukuthi ikhebula elifanele likhethiwe ngohlelo oluthile lwe-thermocople.
Ekugcineni, sinikeza uhla lweIzintambo ze-ThermocoupleNgesevisi eyenziwe ngezifiso, ngakho-ke zizwe ukhululekile ukuxhumana uma udinga!
