I-NTC & Izinzwa Zokushisa 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: i-glass-sealed single-ended, i-bead small black head, i-bead enezintambo eziboshiwe, i-bead enezintambo ezincane, i-clip-on small black head, i-insulating film type, 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 (ukunemba)(1%/3%/5%/10%), i-coefficient yokushisa yokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…), izinto eziyinhlanganisela, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-thermal (index yokushisa), eyi-unit ye-Kelvin temperature (K). I-ceramic ye-semiconductor, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikiswa okuthile. Kukhona kuphela i-B value eyodwa nge-formula ngayinye kanye nezinga lokushisa lokushisela. I-B value ye-NTC thermistor ihambisana ngqo ne-thermal resistance coefficient yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, i-thermal resistance coefficient 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 esingenamkhawulo.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu lokusebenza oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukulinganisa izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, umkhiqizo onenani elikhulu le-B unezinguquko ezinkulu ekumeleni, okungukuthi, lapho inani le-NTC thermistor B likhulu, liyazwela kakhulu lapho lisebenza, 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, ukunemba, kanye nobude be-resistance obudingayo; uma ungacacile ngohlobo, udinga ukusebenzisa izinga lokushisa, indawo yokusetshenziswa, kanye ne-resistance value, i-B value, ukunemba, kanye nobude be-resistance obudingayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuncike kwikhwalithi. 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:Iningi lezinzwa zokushisa zenkampani yethu zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiklamo ehlukene, zineziqhakambiso ezilandelayo ezitholakalayo: uhlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-terminal olukhiyayo, uhlobo lwe-ABS plastic housing, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinazo nezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esitokweni ngokuvamile ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenza 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 kungenjalo kucacile ukuthi hlobo luni lwezinzwa zokushisa ezizosebenzisa, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacacile, sizokuncoma ikhasimende ngokusekelwe endaweni yokusetshenziswa yekhasimende nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungiswa komkhiqizo ngokuhambisana nezidingo zamakhasimende ukuze senze umkhiqizo owanele owudingayo.
Q:Ingabe ihilela imikhiqizo yezintsha zamandla?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwaSiphinde sibe nezingxenye ezisetshenziswa ku-3D printing nezinye izindawo, futhi zibanzi kakhulu.

Q: Ungayithola kanjani i-R-T table ye-NTC thermistor kanye 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 idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
