NTC & inzwa yokushisa Imibuzo Nezimpendulo
U:Yinii-NTC thermistor?Yiziphi izinhlobo ezikhona?
I:Isici sokumelana esehla njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa okungekuhle, 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 enamathiselwe
U: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…
U: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 ngemuva 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 T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, ngokwezindawo ezahlukene zokusetshenziswa 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 kakhulu, isikhathi sokuphendula sishesha.
U:ukuhlelaYiluphi ulwazi okudingeka lunikezwe uma kusetshenziswa i-NTC thermistor?
I:Uma kunohlobo lokumelana oseluvele lunqunyiwe, udinga ukwazisa inani lokumelana,Inani le-B, ukunemba kanye nobude besixhasi esidingekayo; uma ungazi uhlobo, kudingeka ukusetshenziswa kwezinga lokushisa, isimo sokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude besixhasi esidingekayo.
U:I-NTC thermistor isabela ngokushesha okungakanani?
I:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo ekushiseni okusha, futhi kuwumsebenzi wekhwalithi. Uma inzwa incane, isabela ngokushesha. Ijubane lokuphendula lezinzwa ezihlukene lishesha kunezwa efanayo efakwe ngaphakathi kwegobolondo lensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
U:Inzwa yakho yokushisa iyiluphi uhlobo lwenzwa yokushisa? Yiziphi izinhlobo ezikhona?
I:Ama-sensor okushisa ethu amaningi angaphansi kwe-Inzwa yokushisa yohlobo lwe-NTC, ngokuya ngezimo zokusetshenziswa kanye nokwakheka, kukhona uhlobo lwepayipi eliqondile, uhlobo lwentambo, uhlobo lwe-flange, uhlobo lwekhanda lesibhamu, uhlobo lwe-epoxy resin encapsulation, uhlobo lwe-lock terminal, uhlobo lwe-ABS plastic shell kanye nohlobo lwefilimu ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu inezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, ama-thermocouple kanye nezinzwa zokushisa ze-infrared.
U:Ingabe inzwa yakho yokushisa inayo impahla ekhona? Ingabe isekela ukwenziwa ngokwezifiso?
I:Inzwa yokushisa iwumkhiqizo okhethekile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona ikakhulukazi 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 nokukhetha 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 ngokusekelwe esimweni sokusetshenziswa kweklayenti kanye nezidingo ezithile ukuze iklayenti lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi futhi ukulandela izidingo zeklayenti futhi sisebenzisane neklayenti ekulungiseni ukwakheka komkhiqizo, sakhe umkhiqizo owanelisayo odingwa yiklayenti.
U:Ingabe kuhilela imikhiqizo yamandla amasha?
I:Amandla amasha bekuyinto edumile eminyakeni yamuva, kufanele kube khona emikhiqizweni yethu. Hhayi nje amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayisebenzisa, ibanzi kakhulu.

U: Ithebula le-R-T le-NTC thermistor nenzwa yokushisa litholakala kanjani?
I: Yebo, umkhiqizo uzoba netafula le-R-T elihambisanayo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga itafula le-R-T lomkhiqizo ungaxhumana nabantu bethu ukuze uthole usizo.
U: Ingabe inkampani yakho ingasiza ekuklameni umkhiqizo nasekudwebeni imidwebo?
I: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye zomkhiqizo, kufaka phakathi izinto, usayizi kanye nezinye izidingo ezikhethekile, futhi kudingeka futhi ukugunyazwa okukhethekile.
