I-NTC & Izizwa Zokushisa Q&A
Umbuzo:YiniI-NTC thermistor?Zinezinhlobo eziningani?
Impendulo:Ukuphikiswa kwezinto kwehle njengoba izinga lokushisa likhuphuka libizwa ngokuthi ukushisa okungalungile, futhi i-thermistor esetshenziselwa ukubonisa ukushisa okungalungile ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo olulodwa lwe-glass-sealed, uhlobo lwebhola elimnyama elincane, uhlobo lwebhola olune-enamel wire, uhlobo lwebhola olune-plastic wire encane, uhlobo lwebhola elincane elikhiyiwe, uhlobo lwe-insulating film, i-diode,Uhlobo lwamandlakanye ne-resistor ye-chip.
Q:Yiziphi izipikha zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha yobuchwepheshe eyinhloko ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kokumelana (ukunemba)(1%/3%/5%/10%), i-temperature coefficient yokuphikiswa (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)…), inkomba yezinto, isikhathi sokubhekana nazo...
Q:YiniInani le-B le-NTC thermistor?
A:Inani le-B liyinkomba yezinto (i-thermal index) ye-thermistor enezinga lokushisa eliguquguqukayo, elinganiswa nge-Kelvin (K). I-semiconductor ceramic iyabunjwa ngokushisa okuphezulu bese idlula eziqongweni eziningi ukuze kwakheke i-NTC thermistor chip enokuphikisa okuthile. Kunenani elilodwa kuphela le-B nge-formula ngayinye kanye nezinga lokushisa lokubilisa. Inani le-B le-NTC thermistor lihambisana ngqo nezinga lokushisa lokumelana nomkhiqizo, okusho ukuthi, lapho inani le-B likhulu, kulapho nezinga lokushisa lokumelana nalo likhulu.
Ifomula ye-B value ye-NTC thermistor yi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor emazingeni okushisa angu-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi izinketho ezahlukene ze-B zingakhethwa ngokuya ngezimo ezahlukene zokusebenzisa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukulungisa izinga lokushisa, kanye nokuvimbela ukwanda kwe-surge ingasebenzisa inani elikhulu le-B. Ngoba njengoba izinga lokushisa lishintsha, ukuphikiswa kwezinto ezine-B enkulu kushintsha kakhulu, okusho ukuthi, lapho inani le-B le-NTC thermistor likhulu, liyazwela kakhulu lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYimaphi idatha edingekayo lapho usebenzisa inzwa ye-NTC?
A:Uma kukhona uhlobo lokumelana oluqinisekisiwe, udinga ukwazisa ukumelana, Ukuphikiswa okudingekayo, ukunemba, nobude bobude obudingekayo; uma uhlobo lungacacile, khona-ke kudingeka ukushisa, isimo sokusetshenziswa, ukuphikiswa, inani le-B, nokunemba, kanye nobude bobude obudingekayo.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi esidingekayo sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Lapho inzwa incane, iyashesha ukusabela. Izinzwa ezihlukene zisabela ngokushesha kunezinzwa ezifanayo ezigoqwe ezindlini zensimbi. Isikhathi sokuphendula esivamile sezizwa ze-NTC ze-MF52 uchungechunge singaphansi kwemizuzwana engu-15.
Umbuzo:Yiluphi uhlobo lwe-temperature sensor olwenziwa yinkampani yakho? Ziziphi izinhlobo?
Impendulo:Izinzwa zokushisa zenkampani yethu ziningi kakhuluIzinzwa zokushisa zesitayela se-NTC, ngokusekelwe ezimweni ezahlukene zokusebenzisa kanye nezakhiwo, kunezinketho ezifana ne-straight tube type, threaded type, flange type, bullet type, epoxy resin encapsulated type, lock washer terminal type, ABS plastic shell type, kanye ne-thin film type. Ngapaphezu kwalokho, inkampani yethu nayo inezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Umbuzo:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe isekela ukwenziwa ngokwezifiso?
Impendulo:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ingeyohlobo oluvaliwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu ixhasa ukwenziwa ngokwezifiso, ama-thermistor asetshenzisiwe angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nosayizi wezingxenye zensimbi, imodeli, imininingwane, nobude bezintambo, kanye nokukhetha izinhlobo ezahlukene zokuxhuma.
Umbuzo:Uma kungenacaci ukuthi hlobo luni lwezwa lokushisa oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe esimweni sokusebenzisa kanye nezidingo ezithile ukuze ikhasimende lithole imikhiqizo enelisekile. Ngaphezu kwalokho, singakwazi futhi ukubambisana nekhasimende ekwenzeni izinguquko ekwakhiweni komkhiqizo ngesikhathi esifanele ngokuya ngezicelo zekhasimende, ukuze senze imikhiqizo enelisekile edingwa yikhasimende.
Umbuzo:Ingabe kukhona imikhiqizo ehlobene namandla avuselelekayo?
Impendulo:Amandla avuselelekayo ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla avuselelekayo, kodwa futhiSiphinde sibe nemikhiqizo esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene kakhulu.

Umbuzo: Ngingayithola kanjani ithebula le-R-T le-NTC thermistor ne-temperature sensor?
A: Yebo, umkhiqizo uzoba nethebula le-R-T, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga ithebula le-R-T lomkhiqizo, ungaxhumana nabasebenzi bethu.
Umbuzo: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A: Yebo. Ukudweba imidwebo yomkhiqizo kudinga idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
