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 ukusebenza kwezinga lokushisa elibi, futhi i-thermistor esetshenziselwa ukumela ukusebenza kwezinga lokushisa elibi 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, 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 kwe-resistance (ukucaciswa)(1%/3%/5%/10%), i-coefficient yokushisa yokumelana (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…), i-constant yempahla, i-constant yesikhathi…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value yinto engapheli yezinto zokwakha i-thermistor (index yokushisa), eyenziwa nge-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikiswa okuthile. Kukhona kuphela i-B value eyodwa kuwo wonke ama-formula kanye nezinga lokushisa lokushisisa. I-B value ye-NTC thermistor ihambisana ngokuqondile ne-temperature coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, i-temperature coefficient ye-resistance nayo iba nkulu.
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 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 lokusetshenziswa oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokuvimbela 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 kakhulu lapho lisetshenziswa, 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, ukucaciswa, kanye nobude be-resistance obudingekayo; uma ungacacile ngohlobo, khona-ke udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo.
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 esijwayelekile sokuphendula se-MF52 series NTC thermistor sensors singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa ezisetshenziswa yinkampani yakho? Ziziphi izinhlobo?
A:Iningi lezinzwa zethu zokushisa lingolweziIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, zinezinketho ezifana nohlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwesixhumi sesikhiye, uhlobo lwekhava yepulasitiki ye-ABS, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zenu zokushisa zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:I-Temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ngokuvamile ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, ama-thermistor adingekayo angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nosayizi wezingxenye zensimbi, imodeli, imininingwane nobude bezintambo, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenjalo kucacile ukuthi hlobo luni lwe-temperature sensor oluzosetshenziswa, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze likwazi ukuthola umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa imidwebo yomkhiqizo ngesikhathi ngokuya ngezidingo zamakhasimende, ukuze senze umkhiqizo owanele owudingayo.
Q:Ingabe ihilelekile emikhiqizweni yezintsha zamandla?
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 ekwakhiweni kwemikhiqizo nokudwetshwa kwemidwebo?
A: Kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
