Ingcaciso yeMveliso
Uhlobo B ucingo lweThermocouple
Product Overview
Uhlobo lwe-B lwe-thermocouple ucingo luyi-high-performance high-pricious metal thermocouple equkethe i-alloys ezimbini ze-platinum-rhodium: umlenze ofanelekileyo kunye ne-30% ye-rhodium kunye ne-70% yeplatinum, kunye nomlenze ongalunganga kunye ne-6% ye-rhodium kunye ne-94% yeplatinum. Yenzelwe indawo ezinobushushu obuphezulu, yeyona imelana nobushushu phakathi kweethermocouples zentsimbi eqhelekileyo, igqwesa uzinzo kunye nokumelana ne-oxidation kumaqondo obushushu angaphezu kwe-1500 ° C. Ukubunjwa kwayo okungafaniyo kwe-double-platinum-rhodium kunciphisa ukukhukuliseka okubangelwa yi-platinum evaporation, okwenza kube yinto efanelekileyo yokulinganisa ixesha elide lobushushu obuphezulu.
Ukutyunjwa okusemgangathweni
- Uhlobo lwe-Thermocouple: Uhlobo lwe-B (iPlatinum-Rhodium 30-Platinum-Rhodium 6)
- Umgangatho we-IEC: IEC 60584-1
- Umgangatho we-ASTM: ASTM E230
- Ukufakwa kweKhowudi yombala: Umlenze ofanelekileyo - ngwevu; Umlenze ongalunganga - omhlophe (nge-IEC 60751 nganye)
Ezona mpawu
- Ukuchasana nobushushu obugqithisileyo: Ukushisa kwexesha elide lokusebenza ukuya kwi-1600 ° C; ukusetyenziswa kwexesha elifutshane ukuya kuthi ga kwi-1800°C
- I-EMF ephantsi kumaqondo obushushu aphantsi: Imveliso encinci ye-thermoelectric ngaphantsi kwe-50 ° C, ukunciphisa impembelelo yempazamo yesiphambuka esibandayo
- I-Superior High-Temp Stability: ≤0.1% drift emva kweeyure ze-1000 kwi-1600 ° C
- Ukumelana ne-Oxidation: Ukusebenza okugqwesileyo kwi-oxidizing atmospheres; ukumelana nokuphuphuma komphunga kweplatinam
- Amandla omatshini: Ukugcina i-ductility kumaqondo obushushu aphezulu, afanelekile kwiindawo zoshishino ezinzima

Usetyenziso oluqhelekileyo
- Iziko lobushushu obuphezulu (izixhobo ze-ceramic kunye ne-refractory)
- Ukunyibilikiswa kwesinyithi (i-superalloy kunye nemveliso yentsimbi ekhethekileyo)
- Ukwenziwa kweglasi (iglasi edadayo isenza amafurnashi)
- Uvavanyo lwe-aerospace propulsion (imilomo ye-rocket injini)
- Ushishino lweNyukliya (ukubeka iliso kwireactor yobushushu obuphezulu)
Sinikezela ngeendibano ze-thermocouple zodidi lwe-B kunye neetyhubhu zokukhusela i-ceramic kunye nezixhumi zobushushu obuphezulu. Ngenxa yexabiso eliphezulu lezinto eziphathekayo, ubude besampulu bukhawulelwe kwi-0.5-1m kwisicelo, kunye nezatifikethi ezipheleleyo zezinto eziphathekayo kunye neengxelo zokuhlalutya ukungcola. Ulungelelwaniso oluqhelekileyo lweendawo ezithile zomlilo ziyafumaneka.
