Sensor yeTankii S-Type Thermocouple Kuyera Tembiricha Yakakwira uye Kuona Kwakarurama muIndasitiri
Tsananguro yeChigadzirwa
Sensor yeThermocouple yeS-Type (0-1300℃, Kureba kwe250mm)
Pfupiso yeChigadzirwa
Sensor yeS-type thermocouple sensor (platinum-rhodium 10%-platinum, Pt10Rh/Pt) kubva kuTankii Alloy Material chinhu chinoyera kupisa kwakanyanya chakagadzirwa kuti chishandiswe munzvimbo dzinopisa zvakanyanya. Nekugadzirwa kwakagadzirirwa kwe250mm kureba, chubhu yekudzivirira ceramic yekunze 7-8mm, uye waya ye conductor yedhayamita 0.2mm, sensor iyi inowana kuona tembiricha chaiyo pakati pe0-1300℃ kuburikidza neSeebeck effect ye noble metal alloys. Inobatanidzakugadzikana kwakanyanya kwekushisa kwepamusoro,kuyerera kwakaderera kwekuyerwauyekugara kwenguva refu kwechimiro—zvichiita kuti ive sarudzo inosarudzwa yemaitiro ekupisa kwakanyanya akadai sekutarisa tembiricha yemuchina weindasitiri, kuongorora kupisa kwemafuta, uye kuyedza kuvimbika kwezvikamu zvemagetsi.
Mazita Akajairika & Nheyo Yekuvaka
- Giredhi reSensor: S-type (IEC 60584-1 Kirasi 1; yakaenzana neANSI/ASTM E230 Type S) – noble metal thermocouple ine Pt10Rh (positive electrode) uye pure Pt (negative electrode) conductors
- Magadzirirwo Epakati: Kureba kwekupisa 0-1300℃ (kushandiswa kwenguva pfupi kusvika 1400℃ kwe ≤30min); hurefu hwese 250mm (kuyera hurefu hwekupedzisira 50mm, urefu hwewaya ye lead 200mm); chubhu yekudzivirira yeceramic dhayamita yekunze 7-8mm (ukobvu hwemadziro 1.2-1.5mm); dhayamita yewaya ye conductor 0.2mm (kushivirira ± 0.01mm)
- Mitemo Inotevedzera: IEC 60584-1 (thermocouple accuracy class), GB/T 1672-1997 (platinum-rhodium thermocouples), ASTM E230-19 (standard ye noble metal thermocouples)
- Mugadziri: Tankii Alloy Material, ine chitupa cheISO 9001 neISO 14001, ine kugona kunyungudutsa alloy yesimbi inoyevedza uye kugadzirisa sensor.
Mabhenefiti Akakosha (Akagadzirirwa 0-1300℃ & Magadzirirwo Echivakwa)
1. Kuyera Kupisa Kwakanyanya Kunyatsojeka & Kugadzikana
Inoshandisa waya yekufambisa yePt10Rh/Pt ine pureness yakakwira ye99.99% (dhayamita ye0.2mm) ine musanganiswa wakafanana we alloy—kunyatsojeka kwekuyera kunosvika kuKirasi 1 (chikanganiso ≤±1.5℃ pa 0-600℃, ≤±0.25% t pa 600-1300℃, t=tembiricha yakayerwa). Mushure memaawa 1000 ekushanda nguva dzose pa1200℃, thermoelectric potential drift inenge <3μV (yakaenzana netembiricha <0.4℃)—yakakwirira kupfuura K-type thermocouples (drift >10μV pa 800℃) uye yakakodzera kutariswa kwenguva refu kwetembiricha yepamusoro.
2. Kugara Kwechimiro Kwakagadziriswa
- Ceramic Dziviriro Chubhu: 7-8mm dhayamita yekunze ine alumina yakawanda (Al₂O₃ content ≥95%) ine resistance yepamusoro-soro inosvika 1600℃, simba rekudzvanya ≥150MPa—inonyatsobvisa simbi yakanyungudutswa, guruva rechoto, uye magasi anoparadza uku ichivimbisa kushanda zvakanaka kwekupisa (thermal conductivity ≥20 W/(m·K) pa800℃).
- Dhizaini yeConductor & Connection: dhayamita ye0.2mm conductor inoenzanisa kuchinjika uye simba rekupisa kwepamusoro (simba rekudhonza ≥350MPa pa25℃, ≥150MPa pa1300℃); mugumo wekuyera unoshandisa welding yenzvimbo (dhayamita yenzvimbo yeweld 0.3-0.4mm) kuti ive nechokwadi chekuti thermoelectric potential output yakasimba pasina contact resistance.
- Kufananidza Hurefu Hwose: Hurefu hwese hwe250mm (50mm yekuyera magumo + 200mm waya yesimbi) yakagadzirirwa kuiswa pamadziro emoto weindasitiri—inodzivirira kukotama kwakanyanya kwewaya yesimbi uku ichiita kuti magumo ekuyera asvike kunzvimbo yekupisa kwepakati.
3. Kuvimbika Kunoenderana Nekushandiswa
Sensor ine resistance yakanaka yekuoxidation (inogadzira dense PtO₂ protective film pakupisa kwakanyanya) uye resistance yekupisa (inogona kutsungirira 500℃/min tembiricha shanduko pasina ceramic tube cracking). Waya ye lead inoshandisa Teflon insulation inodziya tembiricha yepamusoro (tembiricha yekushanda -60℃ kusvika 260℃) kudzivirira short circuits mumaworkshop ane tembiricha yepamusoro, uye terminal ine standard M12 connector yekubatanidza nekukurumidza kuma transmitters ekupisa.

Maitiro Akajairika Ekushandisa
1. Maitiro Ekushanda Kwemaindasitiri Anopisa Zvikuru
Inoshandiswa pakutarisa tembiricha mumaovheni esimbi ekurapa kupisa (semuenzaniso, kunyungudutsa kwesimbi isina ngura pa900-1100℃) uye mumaovheni esimbi anonyungudutsa (1200-1300℃)—chubhu yesimbi ye7-8mm inodzivirira kukurwa kweguruva remuovheni, uye kurongeka kweClass 1 kunovimbisa kunaka kwechigadzirwa nguva dzose.
2. Kuedzwa kweKuvimbika kweZvikamu zveMagetsi
Inoshandiswa mukuyedzwa kwekukwegura kwe semiconductor chips uye power modules panguva yekupisa kwakanyanya (0-1200℃)— 0.2mm thin conductor uye fast response time (≤2s) inobata nemazvo shanduko dzekupisa dzinoitika panguva yekupisa kwezvikamu, zvichipa rutsigiro rwedata kuti iongororwe kuvimbika.
3. Kuongororwa kweSensor yeDhivharidzo Yepamusoro-Tembiricha
Sechiratidzo chekupisa mumasikiriti ekuongorora tembiricha yepamusoro (semuenzaniso, kugadzirisa maseru emagetsi einjini yemotokari pa800-1000℃)—kubuda kwesimba remagetsi rinogadzikana kunoita kuti maseru emagetsi akwanise kuenzaniswa zvakanaka.
4. Kutsvagurudza kweLabhoritari paTembiricha Yakanyanya
Inoshandiswa mumarabhoritari esainzi yezvinhu pakuedza kuchinja kwechikamu chekupisa kwakanyanya (0-1300℃)—hurefu hwe250mm hwakakodzera maovheni epamusoro, uye NIST calibration inosarudzwa inosangana nezvinodiwa zvekutsvaga data rekutsvaga.
Kuvimbisa Hunhu Hwepamusoro & Rutsigiro rwehunyanzvi
Tankii Alloy Material inoshandisa kudzora kwemhando yeS-type thermocouple sensors ine matanho matatu:
- Kuongorora Kwemutyairi: Kuongororwa kwekuumbwa kwe XRF alloy (kunoita kuti Pt10Rh ive nehuwandu hwe9.5-10.5%) uye kuyedzwa kwekudzivirira kweprobe ye-four-point (kunosimbisa kuchena).
- Kuedzwa kweGungano: Kuongororwa kwekupisa kwakanyanya muchoto chine kunyatsojeka (kunyatsojeka kwekupisa ±0.1℃) uye kuyedzwa kwekupisa (makumi mashanu e25℃-1300℃).
- Kusimbiswa Kwekupedzisira: Kuedza kushanda kwemaawa makumi maviri nemana pa1200℃ kusimbisa kushanda kwemvura inodonha uye kuyedzwa kwemvura inopinzwa neconnector (IP65).
Mienzaniso yemahara (ine mushumo wekugadzirisa) uye gwara rekuisa panzvimbo yacho zvinowanikwa kana zvikakumbirwa. Chikwata chedu chehunyanzvi chinopa mhinduro dzakagadzirwa senge kugadzirisa urefu hwesensor yemidziyo yakakosha uye gwara rekuenzanisa nematransmitter ekupisa kuti ive nechokwadi chekuti kuyera kwakanaka.
