Intshayelelo:

Kwiinkqubo zemveliso yemizi-mveliso, ubushushu ngomnye wemida ebalulekileyo ekufuneka ilinganiswe kwaye ilawulwe. Ekulinganisweni kobushushu, ii-thermocouples zisetyenziswa kakhulu. Zineengenelo ezininzi, ezifana nesakhiwo esilula, ukwenziwa okulula, uluhlu olubanzi lokulinganisa, ukuchaneka okuphezulu, i-inertia encinci, kunye nokudluliselwa okulula kwemiqondiso yokuphuma. Ukongeza, ngenxa yokuba i-thermocouple yi-sensor engasebenziyo, ayidingi mbane wangaphandle ngexesha lokulinganisa, kwaye kulula kakhulu ukuyisebenzisa, ngoko ke idla ngokusetyenziselwa ukulinganisa ubushushu begesi okanye ulwelo kwii-oven kunye nemibhobho kunye nobushushu bomphezulu wezinto eziqinileyo.

Umgaqo wokusebenza:

Xa kukho ii-conductor ezimbini ezahlukeneyo okanye ii-semiconductors u-A no-B zokwenza i-loop, kwaye iziphelo ezimbini ziqhagamshelwe omnye komnye, lo gama nje amaqondo obushushu kwiindawo ezimbini zokudibana ahlukile, ubushushu besinye isiphelo yi-T, ebizwa ngokuba sisiphelo esisebenzayo okanye isiphelo esishushu, kwaye ubushushu besinye isiphelo yi-T0, ebizwa ngokuba sisiphelo sasimahla (esikwabizwa ngokuba sisiphelo sesalathiso) okanye isiphelo esibandayo, amandla e-electromotive aya kuveliswa kwi-loop, kwaye ulwalathiso kunye nobukhulu bamandla e-electromotive bunxulumene nezinto zomqhubi kunye nobushushu beendawo ezimbini zokudibana. Le nto ibizwa ngokuba yi-"thermoelectric effect", kwaye i-loop eyenziwe zii-conductors ezimbini ibizwa ngokuba yi-"thermocouple".

Amandla e-thermoelectromotive anamacandelo amabini, elinye icandelo liyi-contact electromotive force yabaqhubi ababini, kwaye elinye icandelo liyi-thermoelectric electromotive force yomqhubi omnye.

Ubungakanani bamandla e-thermoelectromotive kwi-thermocouple loop bunxulumene kuphela nezinto zomqhubi ezenza i-thermocouple kunye nobushushu bee-junction ezimbini, kwaye abunanto yakwenza nokuma kunye nobukhulu be-thermocouple. Xa izinto ezimbini ze-electrode ze-thermocouple zilungisiwe, amandla e-thermoelectromotive yi-joinction ezimbini temperatures t kunye ne-t0. umsebenzi awulunganga.
