I-NTC & Izinzwa Zokushisa Q&A
Umbuzo:YiniAma-thermistor e-NTC?Yimaphi izinhlobo ezikhona?
A:Ukuphikiswa kwehlisa njengoba izinga lokushisa likhuphuka libizwa ngokuthi yi-negative temperature characteristic, futhi i-thermistor ekhombisa i-negative temperature characteristic ibizwa ngokuthi yi-I-thermistor ye-NTC (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-SMD.
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%), coefficient yokushisa yokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…) , ibanga lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), isici sezinto, isici sesikhathi…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyinani elingumongo we-thermistor (index yokushisa), elingakaniswa ku-Kelvin temperature (K). I-NTC thermistor chip enokuphikiswa okuthile yenziwa ngokuhlanganisa i-ceramic ye-semiconductor ezingeni lokushisa eliphezulu ngokusebenzisa izinqubo eziningi zokucubungula. Kukhona i-B value eyodwa kuphela kuwo wonke amafomula kanye nezinga lokushisa lokuhlanganisa. I-B value ye-NTC thermistor ihambisana ngqo ne-temperature coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value ikhulu, i-temperature coefficient ye-resistance nayo iba nkulu.
Ifomula ye-B ye-thermistor ye-NTC ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-thermistor ye-NTC, elinikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-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 ukukala 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-NTC thermistor B likhulu, liyazwela kakhudlwana lapho lisebenza, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYimaphi idatha edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistance oluqinisekisiwe, udinga ukucacisa i-resistance, ukubekezelelana kwe-resistance (ukunemba), kanye nezinga lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)i-B value, ukunemba, kanye nobude be-resistance obudingekayo; uma uhlobo lungaqinisekile, khona-ke udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance, i-B value, ukunemba, kanye nobude be-resistance obudingekayo.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi esithathayo ukuze kufinyelelwe62% 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 sezimiso ze-MF52 NTC thermistor singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa zenkampani yakho? Yiziphi izinhlobo ezikhona?
A:Izinsizwa zokushisa zenkampani yethu ziningi.Izinzwa zokushisa ze-NTC (Negative Temperature Coefficient Thermal sensitivity resistor), ngokwezimo zokusebenzisa kanye nezakhiwo ezihlukene, kunezinhlobo ezifana ne-straight tube, i-threaded, i-flange, i-bullet head, i-epoxy encapsulated, i-lock washer terminal, i-ABS plastic shell, kanye ne-thin film ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu nayo inezinzwa 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?
Impendulo:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esiyinqolobane ingeyohlobo oluvaliwe nge-epoxy resin, 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.
Umbuzo:Uma kungenjalo ukuthi uhlobo luni lwezinzwa zokushisa oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingaqinisekile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa ukuklama komkhiqizo ngesikhathi esifanele ngokuya ngezicelo zamakhasimende, ukuze senze umkhiqizo owanele owudingayo ikhasimende.
Umbuzo: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 sisebenze nemikhiqizo esetshenziswa ku-3D printing kanye nezinye izindawo, okubanzi kakhulu.

Q: Ungayithola kanjani ithebula le-R-T le-NTC thermistor nezinzwa zokushisa?
Impendulo: Yebo, umkhiqizo uzoba nethebula le-R-T, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga ithebula le-R-T lomkhiqizo, ungaxhumana nabasebenzi benkampani yethu ukuze uthole ulwazi.
Umbuzo: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
Impendulo: Yebo, kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukuhlinzekwa ngemininingwane yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
