I-NTC & Izimiso Zokushisa Q&A
Umbuzo:YiniI-NTC thermistor?Ziziphi izinhlobo?
Impendulo:Ubudlelwano lapho ukumelana kwehlela njengoba izinga lokushisa likhuphuka libizwa ngokuthi ubudlelwano obungezansi bokushisa, futhi i-thermistor esetshenziselwa ukubonisa ubudlelwano obungezansi bokushisa ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile 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, diode,Uhlobo lwamandlakanye ne-resistor ye-surface-mount.
Q:Yiziphi izipho zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A:Imininingwane eyinhloko yobuchwepheshe ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kwezibalo (ukucaciswa)(1%/3%/5%/10%), i-temperature coefficient yokumelana (B value) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)…), isici sezinto, isici sesikhathi...
Q:YiniInani le-B le-NTC thermistor?
A:Inani le-B liyisici sezinto (inani lokushisa) lamathisistor we-B, elinganiswa nge-Kelvin (K). I-semiconductor ceramic iyabunjwa ngokushisa okuphezulu bese idlula eziyisipho eziningi ukuze kwakheke i-NTC thermistor chip enokuphikiswa okuthile, futhi inani elilodwa kuphela le-B elitholakala nge-formula ngayinye kanye nezinga lokushisa lokushisa. Inani le-B le-NTC thermistor lihambisana ngqo ne-coefficient yokushisa yomkhiqizo, okusho ukuthi, lapho inani le-B likhulu, i-coefficient yokushisa yalo iba nkulu.
Ifomula ye-B value ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-T1, T2 ngokulandelana; T1, T2: izinga lokushisa eliphelele.
I-B value ye-NTC thermistor ngokuvamile isuka ku-2000K kuya ku-6000K, futhi ungakhetha i-B value ehlukile ngokuya ngesimo sokusetshenziswa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukulungisa izinga lokushisa, kanye nokuvimbela ukwanda kungasebenzisa i-B value enkulu. Ngoba njengoba izinga lokushisa lishintsha, ukumelana komkhiqizo onama-B value amakhulu kuhluka kakhulu, okusho ukuthi, uma i-B value ye-NTC thermistor inkulu, iyazwela kakhulu lapho isetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYimaphi idatha edingekayo lapho usebenzisa i-NTC thermistor?
A:Uma kukhona uhlobo oluqinisekisiwe lokumelana, udinga ukwazisa inani lokumelana,I-B value, ukunemba, kanye nobude obudingekayo bezintambo; uma ungacacile ngohlobo, udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye nenani lokumelana, i-B value, ukunemba, kanye nobude obudingekayo bezintambo.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi esidingekayo sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Uma inzwa incane, iyashesha ukusabela. Izinzwa ezihlukene zisabela ngokushesha kunezinzwa ezifanayo ezigoqwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezimiso ze-MF52 NTC thermistor singaphansi kwemizuzwana engu-15.
Umbuzo:Yiluphi uhlobo lwe-temperature sensor olwenziwa yinkampani yakho? Ziziphi izinhlobo?
Impendulo:Izinzwa zokushisa zenkampani yethu ziningi zazoIzinzwa zokushisa zesitayela se-NTC, ngokuya ngezimo zokusebenzisa kanye nezakhiwo, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwamapayipi aqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo oluvaliwe nge-epoxy resin, uhlobo lwe-lock sheet terminal, uhlobo lwe-ABS plastic shell, kanye nohlobo lwe-film. Ngaphezu kwalokho, inkampani yethu nayo inezinzwa zokushisa ze-PT100/PT1000, izinza 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 isekela 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 lwesinzwa sokushisa okudingekayo ukuthi lusetshenziswe, ingabe kungenzeka ukuncoma?
A:Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe esimweni sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole imikhiqizo enelisekile. Ngaphezu kwalokho, singasebenzisana nekhasimende ukuze senze 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 iyahlukahlukene kakhulu.

Umbuzo: Ngingayithola kanjani ithebula le-R-T le-NTC thermistor ne-temperature sensor?
A: Yebo, umkhiqizo uzoba ne-R-T table ehambisanayo, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga i-R-T table yomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole ulwazi.
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 kudinga nemvume ekhethekile.
