Iingenelo eziphambili (Zenzelwe i-0-1300℃ kunye neenkcukacha zolwakhiwo)
1. Ubungakanani bokuGcina ubushushu obuphezulu Ukuchaneka kunye nozinzo
Isebenzisa intambo yomqhubi ye-Pt10Rh/Pt engu-99.99% ecocekileyo kakhulu (ububanzi obuyi-0.2mm) enomxube we-alloy ofanayo—ukuchaneka komlinganiselo kufikelela kwiKlasi yoku-1 (impazamo ≤±1.5℃ kwi-0-600℃, ≤±0.25% t kwi-600-1300℃, t=ubushushu obulinganisiweyo). Emva kweeyure ezili-1000 zokusebenza okuqhubekayo kwi-1200℃, i-thermoelectric potential drift yi-<3μV (ilingana nempazamo yobushushu <0.4℃)—ingcono kakhulu kune-K-type thermocouples (drift >10μV kwi-800℃) kwaye ifanelekile ukujonga ubushushu obuphezulu ixesha elide.
2. Ukuqina Kwesakhiwo Okulungiselelweyo

- Uyilo lweConductor kunye noQhagamshelo: Umqhubi we-0.2mm ububanzi ulinganisela ukuguquguquka kunye namandla obushushu obuphezulu (amandla okutsalwa ≥350MPa kwi-25℃, ≥150MPa kwi-1300℃); isiphelo sokulinganisa sisebenzisa i-spot welding (ububanzi be-weld spot yi-0.3-0.4mm) ukuqinisekisa imveliso eqinileyo ye-thermoelectric potential ngaphandle kokumelana nokuchukumisa.
- Ukulingana koBude obupheleleyo: Ubude obupheleleyo obuyi-250mm (isiphelo sokulinganisa esingu-50mm + ucingo lwe-lead oluyi-200mm) lulungiselelwe ukufakwa kodonga olusecaleni lwe-oven yemizi-mveliso—luthintela ukugoba kakhulu kocingo lwe-lead ngelixa luqinisekisa ukuba isiphelo sokulinganisa sifikelela kwindawo yobushushu obuphakathi.
3. Ukuthembeka okuhlengahlengisiweyo kwesicelo
I-sensor inokumelana okuhle kwe-oxidation (yenza ifilimu yokukhusela i-PtO₂ exineneyo kubushushu obuphezulu) kunye nokumelana nokutshatyalaliswa kobushushu (ingamelana nokutshintsha kobushushu obuyi-500℃/min ngaphandle kokuqhekeka kwetyhubhu ye-ceramic). Intambo ye-lead isebenzisa i-insulation ye-Teflon yobushushu obuphezulu (ubushushu bokusebenza obuyi--60℃ ukuya kwi-260℃) ukuthintela iisekethe ezimfutshane kwiindawo zokusebenzela zobushushu obuphezulu, kwaye i-terminal ixhotyiswe ngesixhumi esiqhelekileyo se-M12 sokunxibelelana ngokukhawuleza kwii-transmitters zobushushu.
