I-NTC & I-Temperature Sensor Q&A
Umbuzo:YiniI-NTC thermistor?Zikhona izinhlobo eziningaki?
Impendulo:Ubudleli lapho ukuphikisa kwehlela 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 ezijwayelekile zihlanganisa: uhlobo olulodwa lwe-glass-sealed, uhlobo lwebhola elimnyama elincane, uhlobo lwebhola eline-enamel wire, uhlobo lwebhola eline-plastic wire encane, uhlobo lwebhola elincane elikhethekile, uhlobo lwe-insulating film, diode,Uhlobo lwamandlakanye ne-surface mount resistor.
Q:Yiziphi izipikha zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A:Imininingwane eyinhloko yobuchwepheshe ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kwe-resistance (ukucaciswa)(1%/3%/5%/10%), i-temperature coefficient yokuphikisa (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…), ububanzi lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)…), inani lezinto, 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, 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 nokushisa kokushiswa. 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; RT1, RT2: amanani okumelana kwe-thermistor emazingeni okushisa angu-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
I-B value ye-NTC thermistor ngokuvamile isuka ku-2000K iye 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 lapho izinga lokushisa lishintsha, ukuphikisa komkhiqizo onama-B value amakhulu kuguquguquka kakhulu, okungukuthi, lapho 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 lwe-resistance oluqinisekisiwe, udinga ukwazisa i-resistance, I-B value, ukunemba, kanye nobude obudingekayo bokuphikisa; uma ungacacile ngohlobo, udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye nenani lokuphikisa, i-B value, ukunemba, kanye nobude obudingekayo bokuphikisa.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukuphendula?
A:Isikhathi sokuphendula sichazwa njengesikhathi 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 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...Izinzwa zokushisa zesitayela se-NTC, ngokwezimo ezahlukene zokusebenzisa kanye nezakhiwo, kunezinhlobo ezifana ne-straight tube, i-threaded, i-flange, i-bullet head, i-epoxy resin encapsulated, i-lock piece terminal, i-ABS plastic shell, kanye ne-thin film ongakhetha kuzo. Ngapaphezu 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 kungenzeka ukwenza ngokwezifiso?
Impendulo:Izinzwa zokushisa ziyimikhiqizo ethile, izidingo zamakhasimende ziyahlukahluka, imikhiqizo esitokweni ingeyohlobo oluvaliwe nge-epoxy resin, kunezinhlobo ezimbalwa kakhulu.
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 lwe-temperature sensor oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole imikhiqizo enelisekayo. Ngaphezu kwalokho, singasebenzisana nekhasimende ukuze senze izinguquko ekwakhiweni komkhiqizo ngesikhathi esifanele ngokuya ngezicelo zekhasimende, ukuze senze imikhiqizo enelisekayo 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 ibanzi 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 usizo.
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.
