I-NTC & Izinzwa Zokushisa Q&A
Q:YiniI-NTC thermistor?Yimaphi izinhlobo ezikhona?
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 oluvalwe nge-glass oluhlangothini olulodwa, 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, diode,Uhlobo lwamandlakanye nama-resistors e-chip.
Q:Yimaphi amaparamitha ezobuchwepheshe e-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukuchaneka)(1%/3%/5%/10%), isici sokushisa sokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), izinto eziyisisekelo, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-thermal (thermal index), eyi-unit ye-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikisa okuthile. Kukhona kuphela i-B value eyodwa nge-formula ngayinye kanye nezinga lokushisa lokushisela. I-B value ye-NTC thermistor ihambisana ngokuqondile ne-thermal resistance coefficient yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, i-thermal resistance coefficient yayo iba nkulu.
Ifomula ye-B value ye-NTC thermistor yile: 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 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 ukukala 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, okusho ukuthi, uma inani le-B le-NTC thermistor 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, kudingeka ukuthi kushiwo i-resistance, ukubekezelelana kwe-resistance (ukuchaneka), kanye nobude be-resistance obudingekayo; uma uhlobo lungacacile, kudingeka ukuthi kushiwo izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance, i-B value, ukuchaneka, kanye nobude be-resistance obudingekayo.I-B value, ukuchaneka, kanye nobude be-resistance obudingekayo; uma uhlobo lungacacile, kudingeka ukuthi kushiwo izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance, i-B value, ukuchaneka, kanye nobude be-resistance obudingekayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyisici sekhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi esijwayelekile sokuphendula se-MF52 series NTC thermistor sensors singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa enizisebenzisayo? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiklamo ehlukene, zineziqhakama ezilandelayo ongakhetha kuzo: uhlobo lweshubhu eqondile, uhlobo lwe-thread, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-lug terminal, uhlobo lwe-ABS plastic casing, kanye nohlobo lwe-film. 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:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esiyigcinayo isezingeni eliphezulu iyimikhiqizo evaliwe 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, izinhlobo zezintambo kanye nobude, kanye nokukhethwa kwezinhlobo ezahlukene zama-connectors.
Q:Uma kungenacaci ukuthi hlobo luni lwezinzwa zokushisa okudingeka ukuthi lusetshenziswe, kungenzeka yini ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe esimweni sokusetshenziswa nesidingo esithile ukuze ikhasimende lithole umkhiqizo onelisekayo. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa imidwebo yomkhiqizo ngesikhathi ngokwezidingo zamakhasimende, ukuze senze umkhiqizo onelisekayo owudingayo ikhasimende.
Q:Ingabe ihilelekile emikhiqizweni yezintsha zamandla?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwa futhiSiphinde sibe neqhaza emikhiqizweni esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene kakhulu.

Q: Ungayithola kanjani i-R-T table ye-NTC thermistor nezinzwa zokushisa?
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 ukuthi kunikezwe idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka futhi imvume ekhethekile.
