NTC & inzwa yokushisa Imibuzo Nezimpendulo
U:Yinii-NTC thermistor?Yiziphi izinhlobo ezikhona?
Impendulo:Isici sokumelana esehla njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa okungekuhle, futhi i-thermistor esetshenziselwa ukukhombisa isici sokushisa okungekuhle ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zifaka: uhlobo lwe-single-end glass seal, uhlobo lwe-bead black small head, uhlobo lwe-bead enameled wire, uhlobo lwe-bead small leather wire, uhlobo lwe-card point black small head, uhlobo lwe-insulating film, i-diode,uhlobo lwamandlakanye ne-resistor enamathiselwayo.
Umbuzo:Yiziphi izici zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
I:Amapharamitha ayinhloko ezobuchwepheshe afaka: inani lokumelana elijwayelekile (5K/10K/50K/100K…), ukubekezelelana kwenani lokumelana (ukunemba)(1%/3%/5%/10%), i-coefficient yokushisa yokumelana (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), ububanzi bokushisa okusebenzayo (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), ukungaguquguquki kwento, isikhathi esingaguquki…
Umbuzo:YiniInani le-B le-NTC thermistor?
A:Inani le-B liyisibalo sezinto ezisetshenziswayo se-thermistor ye-coefficient yokushisa (inhloko yokushisa), iyunithi yayo i-Kelvin (K). I-semiconductor ceramic ngemva kokushiswa ngezinga eliphezulu lokushisa idlula ochungechungeni lwezinqubo zokucubungula yakhe i-NTC thermistor chip ene-resistance rate ethile, ukwakheka ngakunye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. Inani le-B le-NTC thermistor lihambisana ne-coefficient yokushisa yokumelana nomkhiqizo, okusho ukuthi uma inani le-B likhulu, i-coefficient yokushisa yokumelana nayo iyakhula.
Ifomula yenani le-B ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inani le-B le-NTC thermistor, linikezwa umkhiqizi; RT1, RT2: inani lokumelana kwe-thermistor emazingeni okushisa u-T1, u-T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, ngokwesikhathi sokusetshenziswa okuhlukahlukene kungakhethwa amanani ahlukene e-B. Ngokuvamile njengomkhiqizo wokulinganisa izinga lokushisa, ukunxephezela izinga lokushisa kanye nokuvimbela i-surge, kungakhethwa inani elikhulu le-B. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo onenani elikhulu le-B ushintsha kakhulu inani lawo lokumelana, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela lapho lisetshenziswa, isikhathi sokuphendula sishesha.
U:ukuhlelaYiluphi ulwazi okudingeka lunikezwe uma kusetshenziswa i-NTC thermistor?
Impendulo:Uma kunohlobo lokumelana oseluvele lunqunyiwe, udinga ukutshela inani lokumelana,Inani le-B, ukunemba kanye nobude besikhiya esidingekayo kuphela; uma ungazi uhlobo, kudingeka izinga lokushisa, indawo yokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude besikhiya esidingekayo.
U:I-NTC thermistor isabela ngokushesha okungakanani?
I:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo ekushiseni okusha, futhi kungumsebenzi wekhwalithi. Uma inzwa incane, ishesha kakhulu ukuphendula. Ijubane lokuphendula lenzwa ehlukile lishesha kunenzwa efanayo efakwe ngaphakathi kwekhabethe lensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
U:Izinzwa zokushisa zekhampani yakho ziluphi uhlobo lwenzwa yokushisa? Yiziphi izinhlobo ezikhona?
I:Ama-sensor okushisa ethu amaningi angaphansi kwe-Inzwa yokushisa yohlobo lwe-NTC, ngokuya ngendawo yokusetshenziswa kanye nokwakheka kwayo, kukhona uhlobo lwepayipi eliqondile, uhlobo lwentambo, uhlobo lwe-flange, uhlobo lwekhanda lesibhamu, uhlobo olufakwe nge-epoxy resin, uhlobo lwethemini lesikhiya, uhlobo lwe-ABS plastic casing kanye nohlobo lwefilimu ezinokukhethwa. Ngaphezu kwalokho, inkampani yethu inezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, i-thermocouple kanye nezinzwa zokushisa ze-infrared.
Umbuzo:Ingabe izinzwa zokushisa zekhampani yakho zikhona esitokweni? Ingabe zisekela ukwenziwa ngendlela oyifunayo?
I:Inzwa yokushisa iwumkhiqizo okhethekile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona esitokweni iningi iwuhlobo oluvalwe nge-epoxy resin, ezinye izinhlobo zincane.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, ama-thermistor okufanele asetshenziswe angakhethwa, ngaphezu kwalokho izingxenye ezingenziwa ngokwezifiso zifaka: ubude nobukhulu kanye nokuma kwezingxenye zensimbi, uhlobo lwezintambo kanye nobude, kanye nokusebenzisa izinhlobo ezahlukene zokuxhuma.
U:Uma kungacaci ukuthi yiluphi uhlobo lwenzwa yokushisa okufanele isetshenziswe, ingabe kungatuswa?
A:Lokhu kunjalo, ngoba izinhlobo zokuxhumana ziningi, uma iklayenti lingacacile, sizoncoma iklayenti ngokusekelwe esimweni sokusetshenziswa kanye nezidingo ezithile zeklayenti, ukuze iklayenti lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi futhi ukulandela izidingo zeklayenti futhi sisebenzisane neklayenti ukulungisa ukwakheka komkhiqizo, sakhe umkhiqizo owanelisayo odingwa yiklayenti.
Umbuzo:Ingabe kuhilela imikhiqizo yamandla amasha?
Impendulo:Amandla amasha kube yinto edumile eminyakeni yamuva, kufanele kube khona emikhiqizweni yethu. Hhayi kuphela amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayihlinzeka, ibanzi kakhulu.

U: Ithebula le-R-T le-NTC thermistor kanye nenzwa yokushisa litholakala kanjani?
Impendulo: Yebo, umkhiqizo uzoba netafula le-R-T elihambisana nawo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga itafula le-R-T lomkhiqizo ungaxhumana nabasebenzi bethu ukuze uthole usizo.
U: Ingabe ikhampani yakho ingasiza ekuklameni umkhiqizo nasekudwebeni imidwebo?
Impendulo: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye ezahlukene zomkhiqizo, kufaka phakathi izinto ezisetshenziswayo, ubukhulu kanye nezinye izidingo ezikhethekile, futhi kudinga futhi ukuthola igunya elikhethekile.
