Imibuzo Nezimpendulo nge-NTC & temperature sensor
Umbuzo:KuyiniI-NTC thermistor?Yiziphi izinhlobo ezikhona?
Impendulo:Isici sokuthi i-resistance yehla njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa esingesihle, futhi i-thermistor esetshenziselwa ukukhombisa isici sokushisa esingesihle ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
ezijwayelekile: uhlobo lwe-single-end glass seal, uhlobo lwe-bead black small head, uhlobo lwe-bead enameled wire, uhlobo lwe-bead small skin wire, uhlobo lwe-card point black small head, uhlobo lwe-insulating film, i-diode、Uhlobo lwamandlakanye ne-chip resistor.
Umbuzo:Yiziphi izici zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
Impendulo:Izici eziyinhloko zobuchwepheshe zifaka: inani le-resistor elijwayelekile (5K/10K/50K/100K…）、ukubekezelelana kwenani lokumelana (ukunemba)(1%/3%/5%/10%)、i-coefficient yezinga lokushisa le-resistance (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…)、ububanzi bezinga lokushisa lokusebenza (℃)(-30℃-105℃/-30℃-125℃/-40℃-250℃…), i-material constant, i-time constant…
Q：YiniI-B value ye-NTC thermistor?
Impendulo:I-B value iyinto engaguquki yezinto ze-thermistor ye-temperature coefficient (i-thermal index), iyunithi yayo i-Kelvin temperature (K). I-semiconductor ceramic ngemva kokushiswa ngezinga lokushisa eliphezulu idlula ochungechungeni lwezinqubo zokucubungula yakhe i-NTC thermistor chip ene-resistivity ethile, ifomula ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. I-B value ye-NTC thermistor ihlobene kahle ne-temperature coefficient ye-resistor yomkhiqizo, okusho ukuthi uma i-B value inkulu, i-temperature coefficient ye-resistor nayo inkulu.
Ifomula yenani le-B ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-NTC thermistor, elinikezwa umkhiqizi; RT1, RT2: inani le-resistance ye-thermistor emazingeni okushisa T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, ngokwezindawo ezahlukene zokusetshenziswa ungakhetha amanani ahlukene e-B. Ngokuvamile, njengomkhiqizo wokulinganisa izinga lokushisa, ukunxephezela izinga lokushisa kanye nokuvimbela i-surge, ungakhetha inani le-B elikhulu. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo onenani le-B elikhulu ushintsha kakhulu kunani lawo lokumelana, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:UkuthengaYiluphi ulwazi okufanele lunikezwe uma kudingeka i-NTC thermistor?
A：Uma kunohlobo lwe-resistor oluvele lunqunyiwe, kudingeka kwaziswe inani le-resistor,Inani le-B, ukunemba kanye nobude be-resistor edingekayo; uma ungazi uhlobo, udinga ukusebenzisa izinga lokushisa, indawo yokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude be-resistor edingekayo.
Umbuzo:Ijubane lokusabela le-NTC thermistor likhulu kangakanani?
A：Isikhathi sokuphendula sichazwa njengokufinyelelaIsikhathi esidingekayo ukuze kufinyelelwe ku-62% noma izinga lokushisa elisha, futhi kuyimisebenzi yesisindo. Uma i-sensor incane, isabela ngokushesha. I-sensor ehlukile isabela ngokushesha kune-sensor efanayo epakishwe ngaphakathi kwegobolondo lensimbi. Isikhathi sokuphendula esijwayelekile se-MF52 series NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Umbuzo:Ama-sensor okushisa enkampani yenu yiluphi uhlobo lwe-sensor yokushisa? Yiziphi izinhlobo ezikhona?
Impendulo:Ama-sensor ethu okushisa amaningi angaphansi kwezinhloboI-NTC temperature sensor, kuye ngendawo yokusetshenziswa kanye nesakhiwo, itholakala ngezinhlobo ezilandelayo: uhlobo lwepayipi eliqondile, uhlobo olunentambo, uhlobo lwe-flange, uhlobo lwekhanda lesibhamu, uhlobo olufakwe nge-epoxy resin, uhlobo lwe-lock terminal, uhlobo lwe-ABS plastic housing kanye nohlobo lwefilimu. Ngaphezu kwalokho, inkampani yethu inama-PT100/PT1000 temperature sensors, ama-DS18B20 temperature sensors, ama-thermocouple kanye nama-infrared temperature sensors.
Umbuzo:Ingabe ama-sensor okushisa enkampani yenu akhona? Ingabe asekela ukuklama?
Impendulo:Ama-sensor okushisa angumkhiqizo okhethekile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liyi-epoxy resin sealed type, ezinye izinhlobo zincane.
Imikhiqizo yethu isekela ukuklama, i-thermistor okufanele isetshenziswe ingakhethwa, ngaphezu kwalokho izingxenye ezingaklanywa zifaka: ubude nobukhulu kanye nokuma kwezingxenye zensimbi, uhlobo lwezintambo kanye nobude, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Umbuzo:Uma kungacaci ukuthi hlobo luni lwe-temperature sensor okufanele isetshenziswe, ingabe kungasuselwa?
Impendulo:Yebo impela, ngoba izinhlobo esixhumana nazo ziningi, uma ikhasimende lingacacisi, sizoncoma ngokusekelwe esimweni sokusetshenziswa kwekhasimende kanye nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi futhi ukulandela izidingo zekhasimende futhi sisize ikhasimende ekulungiseni ukuklama komkhiqizo, senze umkhiqizo owenelisayo odingwa yikhasimende.
Umbuzo:Ingabe kukhona umkhiqizo ohlobene namandla amasha?
Impendulo:Amandla avuselelwayo abe yinto eshisayo eminyakeni yamuva, futhi kufanele abe khona emikhiqizweni yethu. Hhayi nje amandla avuselelwayo,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayisebenzisa, ibanzi kakhulu.

Umbuzo: Ithebula le-R-T le-NTC thermistor ne-temperature sensor litholakala kanjani?
Impendulo: Yebo, umkhiqizo uzoba nethebula le-R-T elihambisana nawo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga ithebula le-R-T eliqondene nomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole usizo.
Umbuzo: Ingabe inkampani yenu ingasiza ekuklameni umkhiqizo, ekudwebeni imidwebo?
A：Kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye ezahlukene zomkhiqizo, kufaka phakathi izinto ezisetshenziswayo, ubukhulu kanye nezinye izidingo ezikhethekile, futhi kudingeka futhi ukugunyazwa okukhethekile.
