Njengoko sonke sisazi, umsebenzi ophambili wee-thermocouples kukulinganisa nokulawula ubushushu. Zisetyenziswa kakhulu kumashishini afana ne-petrochemical, amayeza kunye nokuvelisa. Kwiinkqubo zoshishino, ukujonga ubushushu ngokuchanekileyo kunxulumene kakhulu nolawulo lomgangatho wemveliso kunye nokuphucula ukusebenza kakuhle kwenkqubo. Ke ngoko, ucingo lwe-thermocouple yeplatinum-rhodium lukhetho oluthembekileyo noluchanekileyo phakathi kweentlobo ezininzi zemveliso.
Kodwa yintoni naucingo lwe-thermocouple yeplatinum-rhodiumNgokucacileyo, yi-thermocouple eyenziwe ngeentsimbi ezimbini ezixabisekileyo, iplatinum kunye ne-rhodium, ezenzelwe ngokukodwa ukumelana namaqondo obushushu aphezulu kwaye zibonelele ngomlinganiselo ochanekileyo wobushushu phantsi kweemeko ezinzima. Zombini ezi ntsimbi zikhethwe ngononophelo ngenxa yamanqaku azo aphezulu okunyibilika, ukumelana nokugqwala kunye nobubanzi bobushushu. Iintlobo eziqhelekileyo zentambo ye-thermocouple yeplatinum-rhodium esizibonayo yi-S-type (platinum-10% rhodium/platinum) kunye ne-R-type (platinum-13% rhodium/platinum).
Intambo ye-thermocouple yeplatinum-rhodium ineempawu ezibalulekileyo. Okokuqala, intambo ye-thermocouple yeplatinum-rhodium inokumelana namaqondo obushushu ukuya kuthi ga kwi-1600°C (2912°F), nto leyo eyenza ukuba ifaneleke kwizicelo zobushushu obuphezulu ezifana nokucubungula ubushushu, ukujonga i-furnace kunye nokwenza i-aerospace. Okwesibini, indibaniselwano yeplatinum kunye ne-rhodium kwintambo ye-thermocouple iqinisekisa uzinzo oluhle kakhulu kunye nokuphindaphindwa kokulinganisa ubushushu, nokuba phantsi kweemeko zokusebenza ezinzima. Ukongeza, intambo ye-thermocouple yeplatinum-rhodium ikwanayo nokumelana nokugqwala okunamandla, kunye nexesha lokuphendula ngokukhawuleza, kwaye intambo inokufikelela ekulinganisweni kobushushu okukhawulezayo nokuchanekileyo, okubaluleke kakhulu kwiinkqubo zoshishino eziguqukayo.
Intambo ye-thermocouple yeplatinum-rhodium isetyenziswa kakhulu kwiindawo zoshishino ezineemfuno eziphezulu kakhulu zokulinganisa nokulawula ubushushu obuphezulu. Umzekelo, kwishishini lonyango lobushushu, intambo ye-thermocouple yeplatinum-rhodium isetyenziselwa ukujonga nokulawula ubushushu bee-oven, ii-oven kunye neenkqubo zonyango lobushushu ukuqinisekisa ukuba iimpawu zezinto ezifunekayo ziyafezekiswa. Ukongeza, ishishini leenqwelo-moya lixhomekeke kwintambo yeplatinum-rhodium ukuze lijongwe ngokuchanekileyo ubushushu ngexesha lenkqubo yokwenziwa kwezinto zeenqwelo-moya, iindawo zenjini kunye nezinye izinto eziphambili zeenqwelo-moya. Ishishini lokuvelisa iglasi kunye ne-ceramic liyisebenzisa ukujonga ubushushu bee-oven kunye nee-oven ezisetyenziswa ekuvelisweni kwezinto zeglasi, ii-ceramics kunye nezinto ezichaseneyo.
Kufuphi,ucingo lwe-thermocouple yeplatinum-rhodiumsisixhobo esibalulekileyo sokulinganisa ubushushu ngokuchanekileyo kunye nolawulo kwicandelo lemizi-mveliso elinobushushu obuphezulu. Ukusebenza kwayo okugqwesileyo, uluhlu olubanzi lobushushu kunye nokuthembeka kwenza kube lukhetho lokuqala kumashishini aneemfuno eziphezulu kakhulu zokuchaneka nokuzinza. Nokuba ubandakanyeka ekunyangeni ubushushu, ukuvelisa i-aerospace, ukucutshungulwa kwe-petrochemical, okanye amanye amashishini afuna ukulinganiswa kobushushu obuphezulu, ucingo lwe-platinum-rhodium thermocouple lubonelela ngokuchaneka kunye nokuqina okufunekayo ukuqinisekisa ukusebenza kakuhle kwenkqubo kunye nomgangatho wemveliso.
