Ii-thermocouples zisetyenziswa kumacandelo amaninzi okulinganisa nokulawula ubushushu. Nangona kunjalo, ukuchaneka nokuthembeka kwe-thermocouple akuxhomekanga kuphela kwi-sensor ngokwayo, kodwa nakwintambo esetyenziselwa ukuyidibanisa nesixhobo sokulinganisa. Iintlobo ezimbini eziqhelekileyo zeentambo ezisetyenziselwa ii-thermocouples ziintambo zokuhlawula kunye neentambo zokwandisa. Nangona zinokubonakala zifana, kukho umahluko ocacileyo phakathi kwezi zimbini.
Okokuqala masithethe ngezinto ezibizwa ngokuba ziintambo zokuhlawula i-thermocouple. Iintambo zokuhlawula zenzelwe ngokukodwa ukuqhagamshela ii-sensors ze-thermocouple kwisixhobo sokulinganisa, zihlawulela utshintsho lobushushu kubude bentambo. Ezi ntambo zenziwe ngokudibanisa izinto ezahlukeneyo ezilinganisa iimpawu ze-thermoelectric ze-thermocouple ngokwayo. Oku kuqinisekisa ukuba naluphi na utshintsho lobushushu kubude bentambo aluyi kuchaphazela ukuchaneka komlinganiselo wobushushu.
Eyona nto iphambili kwiintambo zokuhlawula kukuba ziyakwazi ukugcina iipropati ze-thermoelectric ze-thermocouple edibeneyo. Oku kufezekiswa ngokusebenzisa izinto ezineempawu ze-thermoelectric ezifanayo ne-thermocouple, nto leyo ephelisa ngempumelelo naluphi na utshintsho lwe-voltage olubangelwa bubushushu kubude bentambo. Iintambo zokuhlawula ke ngoko zibalulekile ekulinganisweni kobushushu ngokuchanekileyo kwiindawo apho umgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa umde okanye apho imeko-bume yobushushu ingalinganiyo.
Iintambo zokwandisa i-thermocoupleKwelinye icala, zisetyenziselwa ukwandisa ukufikelela kwe-thermocouple ngaphandle kokuphazamisa ukuchaneka komlinganiselo wobushushu. Ngokungafaniyo neentambo ezihlawulelayo, iintambo zokwandisa azilinganisi iimpawu ze-thermoelectric ze-thermocouple. Endaweni yoko, zenziwe ngezinto ezifanayo ne-thermocouple.iingcingo ze-thermocouple, ukuqinisekisa ukuba isignali ye-voltage eveliswa yi-thermocouple idluliselwa ngokuchanekileyo kumgama omde. Umsebenzi ophambili weentambo zokwandisa kukugcina ingqibelelo yesignali ye-voltage eveliswa yi-thermocouple, okuvumela ukuba idluliselwe kumgama omde ngaphandle kokulahleka okanye ukugqwetheka. Oku kubaluleke kakhulu kwiindawo zoshishino apho ii-thermocouples zinokubakho kwiindawo ezinobushushu obuphezulu kwaye izixhobo zokulinganisa zifumaneka kumagumbi olawulo okanye kwiindawo ezikude.
Umahluko phakathi kweentambo zokuhlawula i-thermocouple kunye neentambo zokwandisa
Iimpawu zeThermoelectric: Umahluko omkhulu phakathi kwezi ntlobo zimbini zeentambo ziimpawu zazo zethermoelectric. Iintambo ezihlawulelwayo zenzelwe ukulinganisa iimpawu zethermoelectric zethermocouple, ngelixa iintambo zolwandiso zenziwe ngezinto ezifanayo neentambo zethermocouple ukugcina ingqibelelo yesignali yevoltage.
Imbuyekezo yoBushushu: Iintambo zokuhlawula zenzelwe ngokukodwa ukuhlawula utshintsho lobushushu kubude bentambo ukuqinisekisa ukulinganiswa kobushushu okuchanekileyo. Ngokwahlukileyo koko, iintambo zokwandisa aziboneleli ngembuyekezo yobushushu kwaye zisetyenziselwa ukwandisa uluhlu lwe-thermocouple.
Isicelo Esicacileyo: Iintambo zokuhlawula zibalulekile kwizicelo apho ukutshintsha kobushushu kubude bentambo kunokuchaphazela ukuchaneka kokulinganiswa kobushushu. Iintambo zokwandisa, kwelinye icala, zisetyenziselwa ukudlulisa imiqondiso ye-voltage kumgama omde ngaphandle kokulahleka okanye ukuphazamiseka.
Indlela yokukhetha intambo efanelekileyo
Xa ukhetha intambo efanelekileyo yokusetyenziswa kwe-thermocouple, kufuneka kuqwalaselwe iimfuno ezithile zenkqubo yokulinganisa. Izinto ezifana nomgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa, imeko-bume yobushushu kunye nokuchaneka komlinganiselo wobushushu zibalulekile ekumiseleni imfuneko yentambo yokuhlawula okanye yokwandisa.
Iintambo zokuhlawula zifanelekile xa kusetyenzwa apho umgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa mkhulu okanye apho imeko-bume yobushushu ingalinganiyo. Ezi ntambo ziqinisekisa ukuba utshintsho lobushushu kubude bentambo aluchaphazeli ukuchaneka komlinganiselo wobushushu, ngoko ke zibalulekile kulawulo nokubeka esweni ubushushu ngokuchanekileyo.
Kwelinye icala, iintambo zokwandisa ziyathandwa kwiimeko apho i-thermocouple kufuneka ibekwe kude nesixhobo sokulinganisa. Ezi ntambo zinokudlulisela ngokuchanekileyo isignali ye-voltage eyenziwe yi-thermocouple kumgama omde, ngaloo ndlela zigcina ingqibelelo yokulinganisa ubushushu.
Kubalulekile ukuqaphela ukuba ukusebenzisa uhlobo olungalunganga lwentambo kunokukhokelela ekulinganisweni kobushushu okungachanekanga, okunokuchaphazela umgangatho kunye nokhuseleko lwenkqubo ejongwayo. Kungoko ke kucetyiswa ukuba kuthethwe nomthengisi okanye injineli onamava ukuqinisekisa ukuba intambo echanekileyo ikhethiwe kwisicelo esithile se-thermocouple.
Okokugqibela, sinikezela ngoluhlu lweiintambo ze-thermocouplengenkonzo eyenzelwe wena, ngoko zive ukhululekile ukunxibelelana nathi ukuba kuyimfuneko!
