I-NTC & Ama-temperature sensors: Imibuzo nezimpendulo
Q:YiniI-NTC thermistor?Yimaphi izinhlobo ezikhona?
A:Ukwazi ukuthi ukumelana kwezinto kwehle njengoba izinga lokushisa likhuphuka kubizwa ngokuthi isici sokushisa esibi, futhi i-thermistor esetshenziselwa ukumela lesi sici sokushisa esibi ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo oluvalwe nge-glass oluhlangothini olulodwa, uhlobo lwebhola olunezintambo ezimnyama, uhlobo lwebhola olunezintambo eziboshwe nge-enamel, uhlobo lwebhola olunezintambo ezincane, uhlobo lwebhola olunamachashaza amnyama, uhlobo olune-film olungenawo umoya, i-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 kokumelana (ukucaciswa)(1%/3%/5%/10%), isici sokushisa sokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…) , ububanzi bokushisa bokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), isici sezinto, isikhathi sokudlula…
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 enokumelana okuthile. Kukhona i-B value eyodwa kuphela nge-formula ngayinye kanye nezinga lokushisa lokushiswa. I-B value ye-NTC thermistor ihambisana ngqo ne-thermal coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value ikhulu, i-thermal coefficient ye-resistance nayo 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, ehlinzekwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-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 lokusebenza oluhlukile. 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 inokushintsha okukhulu ekumeleni kwayo, okusho ukuthi, uma inani le-B le-NTC thermistor likhulu, liyazwela kakhulu lapho lisebenza, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimaphi idatha edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lokumelana oluqinisekisiwe, kudingeka ukuthi kushiwo ukumelana, ukubekezelelana (ukucaciswa), kanye nobude obudingekayo bokumelana.i-B value, ukucaciswa, kanye nobude obudingekayo bokumelana; uma uhlobo lungacaciswanga, khona-ke kudingeka ukuthi kusetshenziswe izinga lokushisa, isimo sokusetshenziswa, ukumelana, i-B value, ukucaciswa, kanye nobude obudingekayo bokumelana.
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 esivamile sokuphendula se-MF52 series NTC thermistor sensors singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa zenkampani yakho? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zokushisa zenkampani yethu zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lweshubhu eqondile, uhlobo lwe-thread, uhlobo lwe-flange, uhlobo lwebhola, uhlobo lokupakisha i-epoxy, uhlobo lwe-terminal yokukhiya, uhlobo lwe-ABS plastic housing, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinikeza nezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:I-temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu iyasekelwa ngokwezifiso, ama-thermistor adingekayo angakhethwa, futhi izindawo ezingenziwa ngokwezifiso zihlanganisa: ubude nobude bezingxenye zensimbi, izinhlobo zezintambo kanye nobude, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenacaci ukuthi hlobo luni lwe-temperature sensor oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacaciswanga, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo onelisekayo. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa imidwebo yomkhiqizo ngesikhathi ngokuya ngezidingo zamakhasimende, ukuze senze umkhiqizo onelisekayo owudingayo.
Q:Ingabe ihilelekile emikhiqizweni 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 nezinye izindawo, futhi ububanzi buyanda.

Q: Ungayithola kanjani ithebula le-R-T le-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 ukuthi kunikezwe idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
