I-NTC & I-Temperature Sensor Q&A
Umbuzo:YiniI-NTC thermistor?Zikhona izinhlobo eziningaki?
Impendulo:Ubudlelwano lapho ukuphikisa kwehlisa khona njengoba izinga lokushisa likhuphuka libizwa ngokuthi i-negative temperature characteristic, futhi i-thermistor esetshenziselwa ukubonisa i-negative temperature characteristic 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, diode,Uhlobo lwamandlakanye ne-resistor ye-surface mount.
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 (ukucaciswa)(1%/3%/5%/10%), i-temperature coefficient yokuphikisa (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)…), inkomba yezinto, inkomba yesikhathi...
Q:YiniInani le-B le-NTC thermistor?
A:Inani le-B liyinkomba yezinto ezisetshenziswa kuma-thermistor anomthelela wokushisa (i-thermistor coefficient), elinganiswa nge-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula eziqongweni eziningana zokucubungula ukuze yakhe i-NTC thermistor chip enokumelana okuthile. Kukhona kuphela inani elilodwa le-B ngekhwalithi ngayinye kanye nezinga lokushisa lokushiswa. Inani le-B le-NTC thermistor lihambisana ngokuqondile nomthelela wokushisa womkhiqizo, okusho ukuthi, uma inani le-B likhulu, nomthelela wokushisa womkhiqizo nawo uyanda.
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; i-RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-T1, T2 ngokulandelana; i-T1, T2: isikali sokushisa esiphelele.
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 kwe-surge, ingasebenzisa i-B value enkulu. Ngoba njengoba izinga lokushisa lishintsha, ukuphikisa komkhiqizo onama-B value amakhulu kuguquka 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 udinga i-NTC thermistor?
A:Uma kukhona uhlobo lokumelana oluqinisekisiwe, udinga ukwazisa ukumelana, I-B value, ukunemba, kanye nobude obudingekayo bokuphikisa; uma ungacaciswanga ngohlobo, udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye nenani lokuphikisa, i-B value, ukunemba, kanye nobude obudingekayo bokuphikisa.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi esidingekayo ukuze kufinyelelwe62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Uma inzwa incane, iyashesha ukusabela. Izinzwa ezihlukene zisabela ngokushesha kunezinzwa ezifanayo ezigoqwe ezindlini zensimbi. Isikhathi sokuphendula esivamile sezimiso ze-MF52 NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Umbuzo:Yiluphi uhlobo lwe-temperature sensor olwenziwa yinkampani yakho? Ziziphi izinhlobo?
Impendulo:Izitholi zokushisa zenkampani yethu ziningi kakhuluIzitholi zokushisa zesitayela se-NTC, ngokuya ngezimo zokusebenzisa kanye nokwakhiwa, kunezinketho ezifana ne-straight tube type, threaded type, flange type, bullet type, epoxy resin encapsulated type, lock piece terminal type, ABS plastic shell type, kanye ne-thin film type. Ngapaphezu kwalokho, inkampani yethu nayo inezitholi zokushisa ze-PT100/PT1000, izitholi zokushisa ze-DS18B20, ama-thermocouple, kanye nezitholi zokushisa ze-infrared.
Umbuzo:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe isekela ukwenziwa ngokwezifiso?
Impendulo:Izitholi 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 lwe-temperature sensor 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, 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 eshisa kakhulu 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 kudingeka imvume ekhethekile.
