I-NTC & Izimiso Zokushisa Q&A
Umbuzo:YiniI-NTC thermistor?Ziziphi izinhlobo?
Impendulo:Ubudlelwano lapho ukumelana kwehlela njengoba izinga lokushisa likhuphuka libizwa ngokuthi ubudlelwano obunegative temperature, futhi i-thermistor esetshenziselwa ukubonisa ubudlelwano obunegative temperature 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-skinny wire, uhlobo lwebhola elincane elikhiphekayo, uhlobo lwe-insulating film, diode,Uhlobo lwamandlakanye ne-resistor ye-surface mount.
Q:Yiziphi izipikha zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A:Imininingwane eyinhloko yobuchwepheshe ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kokumelana (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℃)…), inkomba yezinto, isikhathi sokubekezelela...
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, ngemuva kokushiswa ezingeni lokushisa eliphezulu, idlula eziqongweni eziningana zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikisa okuthile. Kukhona kuphela inani elilodwa le-B ngekhwalithi ngayinye nokushisa kokushiswa. Inani le-B le-NTC thermistor lihambisana ngqo nomthelela wokushisa womkhiqizo, okusho ukuthi, lapho inani le-B likhulu, kulapho nomthelela wokushisa uba mkhulu.
Ifomula ye-B value ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho u-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
I-B value ye-NTC thermistor ngokuvamile isuka ku-2000K kuye ku-6000K, futhi ungakhetha i-B value ehlukile ngokuya ngohlobo lokusetshenziswa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukulungisa izinga lokushisa, kanye nokuvimbela ukwanda okunamandla ingasebenzisa i-B value enkulu. Lokhu kungenxa yokuthi njengoba izinga lokushisa lishintsha, ukumelana kwe-B value enkulu kuyashintsha 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 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 njengokufinyelela62% 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 sensor 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, ngokwezimo ezahlukene zokusebenzisa kanye nezakhiwo, kukhona izinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo oluvaliwe nge-epoxy resin, uhlobo lwe-lock washer terminal, uhlobo lwe-ABS plastic shell, kanye nohlobo lwe-film. Ngaphezu kwalokho, inkampani yethu nayo inezinzwa zokushisa ze-PT100/PT1000, izinzi 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, kunezinhlobo ezimbalwa kakhulu.
Imikhiqizo yethu iyakwazi 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 kungenacacile ukuthi hlobo luni lwenzwa yokushisa okudingekayo ukuyisebenzisa, ingabe kungenzeka ukuncoma?
A:Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kwalo nezidingo ezithile, ukuze ikhasimende lithole imikhiqizo enelisekile. Ngaphezu kwalokho, singakwazi futhi ukubambisana nekhasimende ngokushintsha umklamo womkhiqizo ngesikhathi ngokuhambisana nezicelo 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.
