I-Thermocouples isetyenziswa kuluhlu olubanzi lwamashishini ukulinganisa ubushushu kunye nokulawula. Nangona kunjalo, ukuchaneka kunye nokuthembeka kwe-thermocouple akuxhomeki kuphela kwi-sensor ngokwayo, kodwa nakwikhebula elisetyenziselwa ukuyixhuma kwisixhobo sokulinganisa. Iintlobo ezimbini eziqhelekileyo zeentambo ezisetyenziselwa i-thermocouples ziintambo zembuyekezo kunye neentambo zokwandisa. Nangona zisenokubonakala zifana, kukho umahluko ocacileyo phakathi kwezi zimbini.
Okokuqala makhe sithethe malunga nokuba zeziphi iintambo zembuyekezo ze-thermocouple. Iintambo zokuhlawulela zenzelwe ngokukodwa ukudibanisa i-thermocouple sensors kwisixhobo sokulinganisa, ukuhlawulela ukuhluka kweqondo lokushisa ngaphezu kobude bentambo. Ezi ntambo zenziwe ngokudibanisa izinto ezahlukeneyo ezilinganisa iimpawu ze-thermoelectric ze-thermocouple ngokwayo. Oku kuqinisekisa ukuba nayiphi na iqondo lokushisa litshintsha ngaphezu kobude bekhebula aliyi kuchaphazela ukuchaneka komlinganiselo weqondo lokushisa.
Eyona nto iphambili yokuhlawula iintambo kukukwazi kwabo ukugcina iimpawu ze-thermoelectric ze-thermocouple edibeneyo. Oku kuphunyezwa ngokusebenzisa izinto ezineempawu ezifanayo ze-thermoelectric kwi-thermocouple, ngokufanelekileyo ukuphelisa nayiphi na inguqu ye-voltage ebangelwa ukushisa ngaphezu kobude bentambo. Iintambo zokuhlawula ngoko ke ziyimfuneko kumlinganiselo ochanekileyo wokushisa kwizicelo apho umgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa ubude okanye apho indawo yokushisa ayifani.
Iintambo zokwandisa iThermocouple, ngakolunye uhlangothi, zisetyenziselwa ukwandisa ukufikelela kwe-thermocouple ngaphandle kokuphazamisa ukuchaneka komlinganiselo weqondo lokushisa. Ngokungafaniyo neentambo zokuhlawulela, iintambo zokwandisa azilingisi iimpawu ze-thermoelectric ze-thermocouple. Endaweni yoko, zenziwe ngezinto ezifanayo kunye neiingcingo ze-thermocouple, ukuqinisekisa ukuba i-voltage signal eyenziwa yi-thermocouple ihanjiswa ngokuchanekileyo kwimigama emide. Umsebenzi oyintloko weentambo zokwandisa kukugcina ingqibelelo yesignali ye-voltage eyenziwa yi-thermocouple, evumela ukuba idluliselwe kumgama omde ngaphandle kokulahlekelwa okanye ukuphazamiseka. Oku kubaluleke kakhulu kwiindawo zoshishino apho i-thermocouples inokuthi ibekwe kwiindawo eziphezulu zokushisa kunye nezixhobo zokulinganisa zibekwe kumagumbi okulawula okanye kwiindawo ezikude.
Umahluko phakathi kweentambo zembuyekezo ze-thermocouple kunye neentambo zokwandisa
IiPropati zeThermoelectric: Owona mahluko mkhulu phakathi kwezi ntlobo zimbini zeentambo ziimpawu zazo ze-thermoelectric. Iintambo zokuhlawulela zenzelwe ukulinganisa iimpawu ze-thermoelectric ze-thermocouple, ngelixa iintambo zokwandisa zenziwe kwizinto ezifanayo kunye neengcingo ze-thermocouple ukugcina ingqibelelo yesignali yombane.
Imbuyekezo yoBuqondo: Iintambo zokuhlawulela zenzelwe ngokukodwa ukuhlawulela ukuhluka kweqondo lokushisa kunye nobude bentambo ukuze kuqinisekiswe imilinganiselo yokushisa echanekileyo. Ngokwahlukileyo, iintambo zokwandisa aziboneleli ngembuyekezo yeqondo lokushisa kwaye zisetyenziselwa ngokuyinhloko ukwandisa uluhlu lwe-thermocouple.
ISicelo esicacileyo: Iintambo zokuhlawulela zibalulekile kwizicelo apho ukuhluka kweqondo lokushisa kunye nobude bentambo kunokuchaphazela ukuchaneka kwemilinganiselo yokushisa. Iintambo zokwandisa, kwelinye icala, zisetyenziselwa ukuhambisa imiqondiso yombane kumgama omde ngaphandle kwelahleko okanye ukugqwetheka.
Indlela yokukhetha intambo efanelekileyo
Xa ukhetha ikhebula elifanelekileyo kwisicelo se-thermocouple, iimfuno ezithile zenkqubo yokulinganisa kufuneka ziqwalaselwe. Izinto ezifana nomgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa, indawo yokushisa kunye nokuchaneka komlinganiselo weqondo lokushisa kubaluleke kakhulu ekunqumeni imfuno yokuhlawula okanye ikhebula lokwandisa.
Iintambo zokuhlawulela zifanelekile kwizicelo apho umgama phakathi kwe-thermocouple kunye nesixhobo sokulinganisa sikhulu okanye apho indawo yokushisa ayifani. Ezi ntambo ziqinisekisa ukuba utshintsho lokushisa kunye nobude bekhebula aluchaphazeli ukuchaneka komlinganiselo weqondo lokushisa, kwaye ngoko ke luyimfuneko ekulawuleni ukushisa okuchanekileyo kunye nokubeka iliso.
Ngakolunye uhlangothi, iintambo zokwandisa zikhethwa kwiimeko apho i-thermocouple kufuneka ibekwe kude nesixhobo sokulinganisa. Ezi ntambo zinokuhambisa ngokuchanekileyo umqondiso we-voltage owenziwe yi-thermocouple kwimigama emide, ngaloo ndlela igcina ingqibelelo yokulinganisa ubushushu.
Kubalulekile ukuba uqaphele ukuba ukusebenzisa uhlobo olungalunganga lwekhebula kunokukhokelela kwimilinganiselo yokushisa engafanelekanga, enokuchaphazela umgangatho kunye nokhuseleko lwenkqubo esweni. Ngoko ke kucetyiswa ukuba umthengisi onamava okanye injineli idityaniswe ukuqinisekisa ukuba intambo echanekileyo ikhethiwe kwisicelo esithile se-thermocouple.
Ekugqibeleni, sinikezela ngoluhlu lweiintambo ze-thermocouplengenkonzo elungiselelweyo, ngoko zive ukhululekile ukunxibelelana ukuba uyafuna!
