I-Thermocouple, ebizwa nangokuthi i-thermal junction, i-thermoelectric thermometer, noma i-thermel, inzwa esetshenziselwa ukukala izinga lokushisa.Ihlanganisa izintambo ezimbili ezenziwe ngezinsimbi ezihlukene ezihlanganiswe ekugcineni ngakunye.Enye inhlanganisela ibekwa lapho izinga lokushisa kufanele likalwe, kanti enye igcinwa endaweni yokushisa ephansi njalo.Lokhu kuhlangana kulapho izinga lokushisa likalwa khona.Ithuluzi lokulinganisa lixhunywe kusekethe.Lapho izinga lokushisa lishintsha, umehluko wezinga lokushisa ubangela ukuthuthukiswa kwamandla e-electromotive (owaziwa ngokuthi umphumela we-Seebeck, owaziwa nangokuthi umphumela we-thermoelectric,) cishe okulingana nomehluko phakathi kwamazinga okushisa ezingxenye ezimbili.Njengoba izinsimbi ezihlukene zenza ama-voltage ahlukene lapho zivezwe ku-gradient eshisayo, umehluko phakathi kwama-voltage amabili akalwayo uhambisana nezinga lokushisa.Okuyinto engokoqobo ethatha umehluko kumazinga okushisa futhi iwaguqule abe umehluko kumandla kagesi.Ngakho izinga lokushisa lingafundwa kumathebula ajwayelekile, noma ithuluzi lokulinganisa lingalinganiswa ukuze lifunde izinga lokushisa ngokuqondile.
Izinhlobo nezindawo zokusebenzisa ama-thermocouples:
Kunezinhlobo eziningi zama-thermocouples, ngayinye enezici zayo ezihlukile ngokwezinga lokushisa, ukuqina, ukumelana nokudlidliza, ukumelana namakhemikhali, nokuhambisana nesicelo.Uhlobo lwe-J, K, T, & E luyi-thermocouples ye-“Base Metal”, izinhlobo ezivame kakhulu zama-thermocouples.Uhlobo R, S, no-B thermocouples ngama-thermocouples “Noble Metal”, asetshenziswa ekufakweni kokushisa okuphezulu.
Ama-thermocouples asetshenziswa ezimbonini eziningi, ezesayensi, njalonjalo.Angatholakala cishe kuzo zonke izimakethe zezimboni:Ukukhiqiza Amandla, Uwoyela/Igesi,Imishini yokucubungula ukudla,Okugeza okuPlating,Imishini yezokwelapha,Ukucubungula kwasembonini,Ukulawulwa kokulandela umkhondo wamapayipi,Ukwelapha ukushisa kwasembonini,Ukulawula izinga lokushisa esiqandisini,Ukulawula izinga lokushisa kuhhavini, njll.Ama-thermocouples nawo asetshenziswa ezintweni zikagesi zansuku zonke njengezitofu, iziko, ihhavini, isitofu segesi, isifudumezi samanzi segesi, namathosta.
Empeleni, abantu abakhetha ukusebenzisa ama-thermocouples ngokuvamile akhethwa ngenxa yezindleko zabo eziphansi, imikhawulo yokushisa ephezulu, ububanzi obubanzi bezinga lokushisa, kanye nemvelo ehlala isikhathi eside.Ngakho-ke ama-thermocouples angenye yezinzwa zokushisa ezisetshenziswa kakhulu ezitholakalayo.
