Isinyithi esixabisekileyoucingo lwe-thermocouple Uhlobo S, ekwaziwa ngokuba yiPlatinum-Rhodium 10-Platinumucingo lwe-thermocouple, yinto ekwaziyo ukuva ubushushu ngendlela echanekileyo eyenziwe zii-conductors ezimbini zesinyithi ezixabisekileyo. Umlenze olungileyo (RP) yi-platinum-rhodium alloy equlethe i-10% ye-rhodium kunye ne-90% yeplatinum, ngelixa umlenze ongalunganga (RN) uyiplatinum ecocekileyo. Inika ukuchaneka okugqwesileyo kunye nozinzo kwiindawo ezinobushushu obuphezulu, nto leyo eyenza ukuba ibe lolona khetho lukhethwayo lokulinganisa ubushushu ngendlela echanekileyo kwi-metallurgy, kwi-ceramics, nakwii-oven zoshishino ezinobushushu obuphezulu.​

Iimpawu eziQhelekileyo​

• Uhlobo lweThermocouple: Uhlobo lwe-S (iPlatinum-Rhodium 10-Platinum)​

• Umgangatho we-IEC: IEC 60584-1​

• Umgangatho we-ASTM: ASTM E230​

• Ukubhala ikhowudi yombala: Umlenze olungileyo – oluhlaza; Umlenze ongalunganga – omhlophe (ngokwemigangatho ye-IEC)​

Iimpawu eziphambili​

• Uluhlu olubanzi lobushushu: Ukusetyenziswa kwexesha elide ukuya kuthi ga kwi-1300°C; ukusetyenziswa kwexesha elifutshane ukuya kuthi ga kwi-1600°C​

• Ukuchaneka Okuphezulu: Ukuchaneka kweKlasi yoku-1 kunye nokunyamezela kokufunda okungu-±1.5°C okanye ±0.25% (nokuba yeyiphi na enkulu)​

• Uzinzo Olugqwesileyo: Ukushukuma okungaphantsi kwe-0.1% kwi-thermoelectric potential emva kweeyure ezili-1000 kwi-1000°C​
