Ezweni eliyinkimbinkimbi lokulinganisa izinga lokushisa,izintambo ze-thermocoupleisebenza njengamaqhawe angaculwa, evumela ukufundwa kwezinga lokushisa okunembile nokuthembekile kuzo zonke izimboni eziningi. Umnyombo wokusebenza kwawo kunesici esibalulekile—ikhodi yombala yocingo lwe-thermocouple. Kodwa iyini ngempela le khodi yombala, futhi kungani ibalulekile?
Ikhodi yombala yocingo lwe-thermocouple iyisistimu esezingeni eliphezulu eklanyelwe ukuhlukanisa phakathi kwezinhlobo ezahlukene zama-thermocouples. Uhlobo ngalunye lwe-thermocouple lwakhiwe inhlanganisela eyingqayizivele yezinsimbi, ekhiqiza ukuphuma kwe-voltage ethile ehambisana nezinga lokushisa elithile. Le sistimu yokubhala ikhodi isebenza njengolimi lomhlaba wonke lochwepheshe nonjiniyela, ebavumela ukuthi bakhombe ngokushesha uhlobo lwentambo ye-thermocouple abaluphethe. Ngokuqinisekisa ukuxhumana okufanele okusekelwe kukhodi yombala, kuqinisekisa ukufundwa kwezinga lokushisa okuthembekile, ukuvimbela amaphutha abizayo kanye nesikhathi sokuphumula.
Ake sijule kwezinye zezinhlobo ezivame kakhulu ze-thermocouple kanye namakhodi azo ombala ahlobene. Intambo yohlobo lwe-thermocouple yohlobo lwe-J, enomlenze wayo wensimbi ophozithivu kanye nomlenze onegethivu we-constantan, ibonakala kalula ngohlelo lwayo lokubhala amakhodi. Intambo ephozithivu imakwe ngokumhlophe, kanti intambo enegethivu ibomvu. Lolu hlobo luvame ukusetshenziswa ezinhlelweni ezifana nezithando zezimboni namahhavini, lapho lungakwazi ukumelana namazinga okushisa aphakeme futhi lunikeze ukufundwa okunembile.
Uhlobo K, mhlawumbe i-thermocouple evame kakhulu esetshenziswa namuhla, ifaka umlenze ophozithivu we-chromel kanye nomlenze ongemuhle we-amel. Intambo ephozithivu yohlobo K inombala ophuzi, kanti intambo enegethivu ibomvu. Idume ngebanga elibanzi lokushisa kanye nokuzinza okuhle kakhulu, ama-thermocouples ohlobo lwe-K avame ukusetshenziswa ezinqubweni ezehlukene zezimboni, okuhlanganisa ukusebenza kwensimbi, ukukhiqiza amandla, nokucutshungulwa kwamakhemikhali.
OkweThayipha intambo ye-thermocouple T, equkethe umlenze oqondile wethusi kanye nomlenze ongalungile we-constantan, ucingo oluqondile luluhlaza okwesibhakabhaka, futhi ucingo olubi lubomvu. Lolu hlobo lufaneleka kahle ekusetshenzisweni kwezinga lokushisa eliphansi, njengezinhlelo zesiqandisi kanye nokuqapha kwemvelo, ngenxa yokunemba kwayo okuphezulu ebangeni lokushisa eliphansi.
Kwa-Tankii, siyaziqhenya ngokuzibophezela kwethu ekwenzeni kahle uma kuziwa emikhiqizweni yezintambo ze-thermocouple. Izintambo zethu ze-thermocouple zinamathela ngokuqinile kumazinga wokufaka amakhodi wombala wamazwe ngamazwe, okuqinisekisa ukuhambisana okungenamthungo nezinhlelo zokulinganisa ezikhona emhlabeni jikelele. Lokhu akwenzi nje kuphela inqubo yokufaka ibe lula kodwa futhi kunciphisa kakhulu ubungozi bokungaxhumani kahle.
Yakhiwe ngokunemba kusetshenziswa izinto zebanga eliphezulu, izintambo zethu zekhwalithi ephezulu ze-thermocouple zinikeza ukusebenza okungenakuqhathaniswa. Akhiwe ukuze anikeze izilinganiso zokushisa ezinembile nezizinzile kuyo yonke i-spectrum ebanzi yezinhlelo zokusebenza. Kungakhathaliseki ukuthi usebenza endaweni enzima kakhulu yokukhiqiza izimboni, izidingo ezinembile zokucubungula ukudla, noma umkhakha okhethekile wocwaningo lwesayensi, uhla lwethu oluhlukahlukene lwemikhiqizo yezintambo ze-thermocouple likuphathele. Umkhiqizo ngamunye ukhonjwa ngokucacile amakhodi ombala ajwayelekile, okuvumela ukuhlonza okusheshayo nokulula, ukuze ube nethemba eligcwele ekunembeni kwezinga lakho lokushisa - imisebenzi yokuzwa.
Sengiphetha, ikhodi yombala yocingo lwe-thermocouple ingaphezu nje kwenkomba ebonakalayo; kuyingxenye ebalulekile endaweni yokulinganisa izinga lokushisa. Ngemikhiqizo yethu yezintambo ze-thermocouple ezinokwethenjelwa neziphezulu, ungaqiniseka ukuthi izinga lokushisa lakho - imisebenzi yokuqapha izokwenziwa ngokunemba okukhulu nangempumelelo, ikunike amandla okwenza izinqumo ezinolwazi futhi ugcine imisebenzi yakho isebenza kahle.
