Okokuqala, ngokumalunga nokubunjwa kwezinto, i-J - uhlobo lwecingo lwe-thermocouple luqukethe isinyithi - indibaniselwano ye-constantan. Intsimbi isebenza njengomlenze olungileyo, ngelixa i-constantan (aubhedu - i-nickel alloy) isebenza njengomlenze ongalunganga. Ngokwahlukileyo, i-K - uhlobo lwecingo lwe-thermocouple lwenziwe ngechromel- inhlanganisela ye-alum. I-Chromel, eyona nto yenziwe nge-nickel kunye ne-chromium, ngumlenze ofanelekileyo, kunye ne-amel, i-nickel - i-aluminium - i-manganese - i-silicon alloy, ngumlenze ongalunganga. Lo mahluko kwizinto eziphathekayo ukhokelela ekuhlukeni kweempawu zabo zokusebenza.

Okwesibini, amaqondo obushushu abanokuwalinganisa ahluka kakhulu.J - uhlobo lwe-thermocouplesinokulinganisa amaqondo obushushu ukusuka ku -210°C ukuya kuma-760°C. Zifanelekile-zifanelekileyo kwiinkqubo ezahlukeneyo ezineemfuno zobushushu obuphakathi. Umzekelo, kwishishini lokulungisa ukutya, i-J - uhlobo lwe-thermocouples luqhele ukusetyenziswa kwii-oveni zokubhaka. Xa ubhaka isonka, iqondo lobushushu ngaphakathi kwi-oveni lidla ngokusukela kwi-150°C ukuya kuma-250°C. Umgangatho wethu ophezulu we-J - iingcingo zohlobo lwe-thermocouple zinokubeka iliso ngokuchanekileyo la maqondo obushushu, ukuqinisekisa ukuba isonka sibhaka ngokulinganayo kwaye sifezekisa ukuthungwa okugqibeleleyo. Esinye isicelo sikwimveliso yamachiza, apho i-J - uhlobo lwe-thermocouples lusetyenziselwa ukulinganisa ubushushu ngexesha lokumisa amayeza athile. Iqondo lokushisa kule nkqubo lihlala ligcinwa ngaphakathi kwe-50 ° C ukuya ku-70 ° C, kwaye i-J - uhlobo lwemveliso yocingo lwe-thermocouple inokubonelela ngedatha ethembekileyo yobushushu, ikhusela umgangatho wamachiza.

I-K - uhlobo lwe-thermocouples, kwelinye icala, lunoluhlu olubanzi lobushushu, ukusuka kwi-200 ° C ukuya kwi-1350 ° C. Oku kubenza babaluleke kakhulu kwizicelo zobushushu obuphezulu. Kwishishini lokwenza intsimbi,K - uhlobo lwe-thermocoupleszisetyenziselwa ukujonga ubushushu ngaphakathi kwesithando somlilo. Amaqondo obushushu kwiziko eliqhumayo angafikelela kwi-1200°C okanye nangaphezulu. Iintambo zethu ze-K - uhlobo lwe-thermocouple ziyakwazi ukumelana nobushushu obunjalo ngelixa zigcina ukuchaneka okuphezulu, ukuvumela abaqhubi ukuba balawule ngokuchanekileyo inkqubo yokunyibilikisa kunye nokuqinisekisa umgangatho wentsimbi. Kwintsimi ye-aerospace, ngexesha lokuvavanywa kwezixhobo ze-jet injini, i-K - uhlobo lwe-thermocouples lusetyenziselwa ukulinganisa iigesi eziphezulu zokushisa ezenziwe ngexesha lokusebenza kwe-injini. Ezi gesi zinokufikelela kumaqondo obushushu asondele kwi-1300 ° C, kwaye iimveliso zethu zocingo lwe-thermocouple zohlobo lwe-K zinokubonelela ngofundo oluchanekileyo lobushushu, oluyimfuneko ekuphuhliseni nasekuphuculeni iinjini zejethi.

Ukuchaneka yenye inkalo ephambili. I-K - uhlobo lwe-thermocouples ngokubanzi lunikeza ukuchaneka okungcono kuluhlu olubanzi lobushushu xa kuthelekiswa no-J - uhlobo lwe-thermocouples. Uzinzo lwe-K - uhlobo lwe-thermocouples kwiindawo ezinzima lukwanegalelo ekuchanekeni kwabo okuphezulu, okwenza kube yinto ekhethiweyo yophando lwezenzululwazi kunye neenkqubo ezichanekileyo zoshishino.

E-Tankii, iimveliso zocingo lwe-J kunye ne-K ze-thermocouple zenziwe ngolawulo olungqongqo lwekhwalithi. I-J yethu - iingcingo zohlobo lwe-thermocouple ziqinisekisa ukusebenza okuthembekileyo ngaphakathi koluhlu lwabo lobushushu obuchaziweyo, ngelixa i-K - iingcingo zohlobo lwe-thermocouple ziyilelwe ukumelana nobushushu obuphezulu ngokuchaneka okugqwesileyo kunye nokuzinza. Nokuba ufuna ukulinganisa ubushushu obuphantsi - iinkqubo zokukhenkceza ubushushu okanye ubushushu bobushushu obuphezulu, iimveliso zethu zocingo lwe-thermocouple zinokukubonelela ngedatha yobushushu obuchanekileyo kunye nozinzile, kukunceda wenze imisebenzi yakho kwaye uqinisekise umgangatho wemveliso.
