I-NTC & Izinzwa Zokushisa Q&A
Q:YiniAma-NTC thermistor?Yimaphi izinhlobo ezikhona?
A:Ukuphikiswa kwe-resistance kwehlela njengoba izinga lokushisa likhuphuka libizwa ngokuthi i-negative temperature characteristic, futhi i-thermistor esetshenziselwa ukubonisa i-negative temperature characteristic ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: i-glass-sealed type, i-bead type black head, i-bead type enezintambo eziboshiwe, i-bead type enezintambo ezincane, i-clip-on type black head, i-insulating film type, i-diode,Uhlobo lwamandlakanye nama-resistors e-surface mount.
Q:Yimaphi amaparamitha ezobuchwepheshe e-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa ngokuthi (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukunemba)(1%/3%/5%/10%), coefficient yokushisa yokumelana (B value) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃...), constants yezinto, isikhathi sokubala...
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sokushisa kwe-thermistor (index yokushisa), 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-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 ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor emazingeni okushisa angama-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 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, udinga ukunikeza i-resistance value,i-B value, ukunemba, kanye nobude be-resistance obudingekayo; uma ungacacile ngohlobo, udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukunemba, kanye nobude be-resistance obudingekayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% 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 zenkampani yakho? Zinezinhlobo eziningaki?
A:Izinsizwa zokushisa zenkampani yethu ziningi.Izinsizwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, zihlanganisa uhlobo oluqondile, uhlobo olune-thread, uhlobo olune-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-lock washer terminal, uhlobo lwe-ABS plastic shell, kanye nohlobo oluyisicaba ongakhetha kuzo. Ngaphezu kwalokho, sinama-PT100/PT1000 temperature sensors, ama-DS18B20 temperature sensors, ama-thermocouples, kanye nama-infrared temperature sensors.
Q:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esitokweni ikakhulu i-epoxy resin-sealed type, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu iyasekelwa ngokwezifiso, ama-thermistor adingekayo angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nosayizi wezingxenye zensimbi, izinhlobo zezintambo, ubude, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenjalo kucacile ukuthi hlobo luni lwezinzwa zokushisa okufanele zisetshenziswe, 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 nokulungisa ukuklama komkhiqizo ngesikhathi ngokuya ngezicelo zamakhasimende, ukuze senze umkhiqizo owanele owudingayo ikhasimende.
Q:Ingabe kukhona imikhiqizo ehlobene namandla amasha?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwaSiphinde sibe nemikhiqizo esetshenziswa ku-3D printing kanye nezinye izindawo, ezibanzi kakhulu.

Q: Ungayithola kanjani i-R-T table ye-NTC thermistor kanye nezinzwa zokushisa?
A: Yebo, umkhiqizo uzoba 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: Yebo, kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukuhlinzekwa ngemininingwane yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka futhi ukuthola imvume ekhethekile.
