Okokuqala, ngokwendlela izinto ezisetyenziswa ngayo, ucingo lwe-thermocouple yohlobo lwe-J luqulathe indibaniselwano yentsimbi ne-constantan. Intsimbi isebenza njengomlenze olungileyo, ngelixa i-constantan (ai-alloy yobhedu-nickel) isebenza njengomlenze ongalunganga. Ngokwahlukileyo koko, ucingo lwe-thermocouple yohlobo lwe-K lwenziwe nge-i-chromel- indibaniselwano ye-alumiyeli. I-Chromel, eyenziwe kakhulu yi-nickel kunye ne-chromium, ngumlenze olungileyo, kwaye i-alumiyeli, i-nickel-aluminium-manganese-silicon alloy, ngumlenze ongalunganga. Lo mahluko kwizinto ezibonakalayo ukhokelela kwiinguqu kwiimpawu zazo zokusebenza.

Okwesibini, imigangatho yobushushu abanokuyilinganisa iyahluka kakhulu.Ii-thermocouples zohlobo lwe-JNgokwesiqhelo zinokulinganisa amaqondo obushushu ukusuka kwi -210°C ukuya kwi-760°C. Zilungele ukusetyenziswa ngeendlela ezahlukeneyo ezineemfuno zobushushu obuphakathi. Umzekelo, kwishishini lokucubungula ukutya, ii-thermocouples zohlobo lwe-J zisetyenziswa kakhulu kwii-oven zokubhaka. Xa kubhakwa isonka, amaqondo obushushu ngaphakathi kwi-oven adla ngokuba phakathi kwe-150°C ukuya kwi-250°C. Iintambo zethu ze-thermocouple zohlobo lwe-J ezikumgangatho ophezulu zinokujonga ngokuchanekileyo la maqondo obushushu, ziqinisekise ukuba isonka sibhakwa ngokulinganayo kwaye sifezekisa ubume obugqibeleleyo. Esinye isicelo sikwimveliso yamayeza, apho ii-thermocouples zohlobo lwe-J zisetyenziselwa ukulinganisa amaqondo obushushu ngexesha lenkqubo yokomisa amayeza athile. Amaqondo obushushu kule nkqubo ahlala egcinwe ngaphakathi kwe-50°C ukuya kwi-70°C, kwaye iimveliso zethu zeentambo ze-thermocouple zohlobo lwe-J zinokubonelela ngedatha yobushushu ethembekileyo, zikhusela umgangatho wamayeza.

Kwelinye icala, ii-thermocouples zohlobo lwe-K zinomlinganiselo obanzi wobushushu, ukusuka kwi-200°C ukuya kwi-1350°C. Oku kuzenza zibe yimfuneko kakhulu kwiindlela zobushushu eziphezulu. Kwishishini lokwenza intsimbi,Ii-thermocouples zohlobo lwe-Kzisetyenziselwa ukujonga ubushushu ngaphakathi kwesithando somlilo esiqhumayo. Ubushushu kwisithando somlilo esiqhumayo bunokufikelela kwi-1200°C okanye ngaphezulu. Iintambo zethu ze-thermocouple zohlobo lwe-K zinokumelana nobushushu obugqithisileyo ngelixa zigcina ukuchaneka okuphezulu, okuvumela abaqhubi ukuba balawule ngokuchanekileyo inkqubo yokunyibilikisa nokuqinisekisa umgangatho wentsimbi. Kwicandelo leenqwelo-moya, ngexesha lokuvavanya izinto zenjini yejethi, ii-thermocouple zohlobo lwe-K zisetyenziselwa ukulinganisa iigesi zobushushu obuphezulu eziveliswa ngexesha lokusebenza kwenjini. Ezi gesi zinokufikelela kubushushu obukufutshane ne-1300°C, kwaye iimveliso zethu zeentambo ze-thermocouple zohlobo lwe-K zinokubonelela ngokufundwa kobushushu okuchanekileyo, okubalulekileyo ekuphuhlisweni nasekuphuculweni kweenjini zejethi.

Ukuchaneka yenye into ebalulekileyo. Ii-thermocouples zohlobo lwe-K ngokubanzi zibonelela ngokuchaneka okungcono kumanqanaba obushushu abanzi xa kuthelekiswa nee-thermocouples zohlobo lwe-J. Uzinzo lwee-thermocouples zohlobo lwe-K kwiindawo ezinzima lukwanegalelo ekuchanekeni kwazo okuphezulu, nto leyo eyenza ukuba zibe lukhetho olukhethwayo lophando lwesayensi kunye neenkqubo zoshishino ezichaneke kakhulu.

KwaTankii, iimveliso zethu ze-thermocouple wire ze-J kunye ne-K zenziwe ngolawulo olungqongqo lomgangatho. Iintambo zethu ze-thermocouple type J ziqinisekisa ukusebenza okuthembekileyo ngaphakathi koluhlu lwazo lobushushu oluchaziweyo, ngelixa iintambo zethu ze-thermocouple type K zenzelwe ukumelana nobushushu obuphezulu ngokuchanekileyo nangokuzinza okugqwesileyo. Nokuba ufuna ukulinganisa iinkqubo zokukhenkceza ezinobushushu obuphantsi okanye ukusabela kwezoshishino ezinobushushu obuphezulu, iimveliso zethu ze-thermocouple wire zinokukunika idatha yobushushu echanekileyo nezinzileyo, ikuncede uphucule imisebenzi yakho kwaye uqinisekise umgangatho wemveliso.
