B-Type Thermocouple Wire yeKunyanya Kupisa Kwenzvimbo Kwakakwana Kuonekwa Kwekupisa
Product Description
Type B Thermocouple Wire
Product Overview
Rudzi rweB thermocouple wire isimbi yakakosha yesimbi inonzi thermocouple ine maviri eplatinum-rhodium alloys: gumbo rakanaka rine 30% rhodium uye 70% platinum, uye gumbo rakashata rine 6% rhodium uye 94% platinum. Yakagadzirirwa kunyanyisa kutonhora kwemamiriro ekunze, ndiyo inonyanya kushingirira kupisa pakati pezvakajairwa simbi yakakosha thermocouples, inokunda mukugadzikana uye oxidation kuramba patembiricha inopfuura 1500 ° C. Yayo yakasarudzika mbiri-platinum-rhodium kuumbwa kunoderedza kudonha kunokonzerwa neplatinamu evaporation, zvichiita kuti ive yakanaka kune yakareba-yepamusoro-yekushisa kuyerwa.
Standard Mazita
- Thermocouple Type: B-mhando (Platinum-Rhodium 30-Platinum-Rhodium 6)
- IEC chiyero: IEC 60584-1
- ASTM Standard: ASTM E230
Key Features
- Yakanyanya Temperature Resistance: Yenguva refu yekushanda tembiricha kusvika 1600 ° C; kushandiswa kwenguva pfupi kusvika 1800 ° C
- Yakaderera EMF pane Yakaderera Tembiricha: Minimal thermoelectric kubuda pazasi 50 ° C, kuderedza kutonhora junction kukanganisa kukanganisa
- Superior High-Temp Kugadzikana: ≤0.1% kudonha mushure memaawa 1000 pa1600 ° C
- Oxidation Resistance: Kuita kwakanakisa mune oxidizing atmospheres; inopikisa platinum evaporation
- Mechanical Strength: Inochengetedza ductility pane tembiricha yakakwira, yakakodzera kune dzakaoma maindasitiri nharaunda

| Custom Options | Precision kucheka, kupenya kwepamusoro kwepamusoro-kuchena maapplication |
Typical Applications
- High-temperature sintering furnaces (ceramic uye refractory zvinhu)
- Metal smelting (superalloy uye yakakosha simbi kugadzirwa)
- Girazi kugadzira (yayangarara girazi kugadzira mavira)
- Aerospace propulsion test (rocket injini nozzles)
- Indasitiri yeNuclear (yepamusoro-temperature reactor monitoring)
Isu tinopa Type B thermocouple magungano ane ceramic ekudzivirira machubhu uye yakakwirira-tembiricha yekubatanidza. Nekuda kwekukosha kwezvinhu, hurefu hwemuenzaniso hunogumira ku 0.5-1m pakukumbira, inoperekedzwa nezvitupa zvezvinhu zvizere uye mishumo yekuongorora kusachena. Magadzirirwo ega ega enzvimbo dzechoto chaiwo anowanikwa
