Inkcazo emfutshane:

Chwetheza i-termocouple cire luhlobo lobushushu olona lungelo losapho lwe-thermocouple, owaziwayo ngokuchaneka kobushushu obuphezulu kunye nozinzo. Iqulathe iingcingo ezimbini ezahlukeneyo zentsimbi zajoyina kwelinye icala, zihlala zenziwe zeplatinam-rhodium. Kwimeko yohlobo lwe-thermocouples, ucingo olunye lwenziwe ngama-70% iplatinam kunye ne-30% i-rhodium30), ngelixa enye icingo lenziwe nge-Platinam kunye ne-6% i-6% yeRhodium (Pt94h6).

Chwetheza i-thermocouples zenzelwe ukulinganisa ubushushu obuphakamileyo, ukusukela kwi-0 ° C ukuya kwi-1820 ° C (32 ° ukuya kwi-3308 ° 0.) f). Ziqhelekile ezisetyenziswa kwizicelo ezifana nezixhobo zemizi-mveliso, i-kilns, kunye novavanyo olunobushushu obuphezulu. Ngenxa yendibaniselwano yezinto ezisetyenzisiweyo, chwetheza i-thermocouples ibonelela ngezithixo ezigqwesileyo kunye nokuchaneka, ngakumbi kumaqondo obushushu aphezulu.

Ezi termocouples zikhethwa kwiimeko apho kufuneka kakhulu, nangona zinexabiso elikhulu kunezinye iintlobo ze-thermocouples. Ukuchaneka kwabo nokuzinza kubenza balungele ukufumana izicelo ezifunwayo kumashishini anje nge-aerospace, inqwelo moya, kunye ne-metaltorgy.
