I-NTC & I-Temperature Sensor Q&A
Q:YiniI-NTC thermistor?Yiziphi 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-resistor e-chip.
Q:Yimiphi imingcele yobuchwepheshe ye-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa ngokuthi (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukucaciswa)(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 eziyinhloko, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-temperature (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 enokuphikiswa okuthile. Kukhona kuphela i-B value eyodwa kuwo wonke amafomula kanye nezinga lokushisa lokushiswa. 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 yile: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-NTC thermistor, elinikezwa 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 amanani ahlukene e-B ngokuya ngezindawo ezahlukene zokusebenzisa. Ngokuvamile, imikhiqizo esetshenziselwa ukulinganisa izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungakhetha amanani aphezulu e-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B inokumelana okukhulu okushintshayo, okusho ukuthi, lapho inani le-B le-NTC thermistor likhulu, liyazwela kakhulu lapho lisebenzisa, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimiphi imininingwane edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistance oluqinisekisiwe, kudingeka ukuthi kushiwo i-resistance value,i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo; uma uhlobo lungacacile, khona-ke kudingeka ukuthi kusetshenziswe 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 kuncike kukhwalithi. 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 enizisebenzisayo? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lweshubhu eqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-terminal lock, uhlobo lwe-ABS plastic shell, 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:I-temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingeyohlobo 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, 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 lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungiswa komkhiqizo ngokuhambisana nezidingo zamakhasimende ukuze senze umkhiqizo owanele owudingwa yikhasimende.
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 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 ukuhlinzekwa ngemininingwane yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka futhi imvume ekhethekile.
