I-NTC & Ama-Temperature Sensors Q&A
Q:YiniI-NTC thermistor?Yimaphi izinhlobo?
A:Ukwazi ukuthi ukumelana kwe-elekthrikhi kwehle njengoba izinga lokushisa likhuphuka kubizwa ngokuthi isici esibi sokushisa, futhi i-thermistor esetshenziselwa ukumela lesi sici esibi sokushisa ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo oluhlanganiswe nge-glass oluhlangene, uhlobo lwebhola olune-head encane emnyama, uhlobo lwebhola olune-enamel wire, uhlobo lwebhola olune-wire encane yesikhumba, uhlobo lwe-clip-on olune-head encane emnyama, uhlobo lwe-insulating film, i-diode,Uhlobo lwamandlakanye nama-resistors e-SMD.
Q:Yimaphi amaparamitha ezobuchwepheshe e-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukunemba)(1%/3%/5%/10%), isici sokushisa sokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…), izinto eziyinhloko, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-temperature (inani le-thermal), elingakaniswa ku-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokumelana okuthile. Kukhona kuphela i-B value eyodwa kuwo wonke amafomula kanye nezinga lokushisa lokushiswa. I-B value ye-NTC thermistor ihambisana ngqo ne-temperature coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, kulapho i-temperature coefficient ye-resistance iba nkulu.
Ifomula ye-B value ye-NTC thermistor yile: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-NTC thermistor, elinikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor lapho izinga lokushisa lingama-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu oluhlukile lwezicelo. Ngokuvamile, imikhiqizo esetshenziselwa ukulinganisa izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B inokumelana okukhulu okushintshayo, okungukuthi, lapho inani le-NTC thermistor B likhulu, liyazwela kakhudlwana lapho lisebenzisa, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimaphi idatha edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistance oluqinisekisiwe, udinga ukwazisa i-resistance value,i-B value, ukunemba, kanye nobude be-resistance obudingayo; uma ungacaciswanga uhlobo, khona-ke udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukunemba, kanye nobude be-resistance obudingayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezimiso ze-MF52 NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa ezikunikezayo? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, zinezingubo zokushisa ezilungele ukukhethwa, izinhlobo zokubopha, izinhlobo zama-flange, izinhlobo zamabhomu, izinhlobo ezifakwe i-epoxy, izinhlobo zamalokhi, izinhlobo zamacasingi epulasitiki e-ABS, kanye nezinhlobo ezincane. Ngaphezu kwalokho, sinezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zakho zokushisa zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:I-Temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingohlobo oluhlanganiswe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, futhi ama-thermistor adingekayo angakhethwa. Ngaphezu kwalokho, izingxenye ezingenziwa ngokwezifiso zihlanganisa: ubude nobude bezingxenye zensimbi, imodeli, imininingwane, nobude bezintambo, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenjalo kucaciswe ukuthi hlobo luni lwe-temperature sensor oluzosetshenziswa, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacaciswanga, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo onokwaneliseka. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokwenza izinguquko ekwakhiweni komkhiqizo ngesikhathi esifanele ngokuya ngezidingo zamakhasimende, ukuze senze umkhiqizo onokwaneliseka owudingayo.
Q:Ingabe ihilela imikhiqizo yezintsha ezintsha?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwaSiphinde sibandakanyeke emikhiqizweni esetshenziswa ku-3D printing kanye nezinye izindawo, futhi siyahlukahlukene kakhulu.

Q: Ungayithola kanjani i-R-T table ye-NTC thermistor kanye ne-temperature sensor?
A: Yebo, imikhiqizo izoba nethebula le-R-T, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga ithebula le-R-T lomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole ulwazi.
Q: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A: Kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
