Q:KuyiniNTC thermistor?Yiziphi izinhlobo ezikhona?
A:Isici sokumelana esehla njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa esingesihle, futhi i-thermistor esetshenziselwa ukukhombisa isici sokushisa esingesihle ibizwa ngokuthiNTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zifaka: uhlobo lwe-single-end glass seal, uhlobo lwe-bead black head encane, uhlobo lwe-bead enameled wire, uhlobo lwe-bead small leather wire, uhlobo lwe-clip-on black head encane, uhlobo lwe-insulating film, i-diode、Uhlobo lwamandlakanye ne-chip resistor.
Q:Yiziphi izici zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A:Izici eziyinhloko zobuchwepheshe zihlanganisa: inani lokumelana elibekiwe (5K/10K/50K/100K…), ukubekezelelana kwesilinganiso sokumelana (ukunemba)(1%/3%/5%/10%)、i-coefficient yokushisa yokumelana (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…), ibanga lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…)、into engaguquki yezinto zokwakha、isikhathi esingaguquki…
Q:YiniInani le-B le-NTC thermistor?
A:I-B value iyinto engaguquki yezinto zokwakha ze-thermistor ye-coefficient yokushisa (i-thermal index), futhi iyunithi yayo i-Kelvin temperature (K). I-ceramic semiconductor ngemva kokushiswa ngezinga lokushisa eliphezulu idlula ochungechungeni lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip ene-resistivity ethile, futhi inhlanganisela ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa kuphela le-B. I-B value ye-NTC thermistor ihlobene kahle ne-coefficient yokushisa yokumelana nomkhiqizo, okusho ukuthi uma i-B value inkulu, i-coefficient yokushisa yokumelana nayo inkulu.
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.
I-B value ye-NTC thermistor ngokuvamile iphakathi kuka-2000K no-6000K, futhi i-B value ehlukene ingakhethwa ngokusekelwe ezinhlelweni ezahlukene zokusetshenziswa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukunxephezela izinga lokushisa, kanye nokuvimbela i-surge ingasebenzisa i-B value enkulu. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo one-B value enkulu ushintsha kakhulu ekumelaneni kwawo, okusho ukuthi uma i-B value ye-NTC thermistor inkulu, iyazwela kakhulu lapho isetshenziswa, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYiluphi ulwazi okudingeka lunikezwe uma kusetshenziswa i-NTC thermistor?
A:Uma sekunesimo sokumelana esivele sinqunyiwe, kudingeka kwaziswe inani lokumelana,Inani le-B, ukunemba kanye nobude bokumelana okudingekayo; uma ungazi uhlobo, kudingeka ukusebenzisa izinga lokushisa, isimo sokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude bokumelana okudingekayo.
Q:Ijubane lokuphendula le-NTC thermistor likhulu kangakanani?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo ekushiseni okusha, futhi kungumsebenzi wengqondo. Uma inzwa incane, isabela ngokushesha. Izinzwa ezihlukene zisabela ngokushesha kunezwa efanayo efakwe ngaphakathi kwegobolondo lensimbi. Isikhathi sokuphendula esijwayelekile se-MF52 series NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Q:I-temperature sensor yekhampani yenu iwuhlobo luni lwe-temperature sensor? Yiziphi izinhlobo ezikhona?
A:Izinzwa zethu zokushisa ziningi ziyi-Inzwa yokushisa yohlobo lwe-NTC, ngokuya ngesimo sokusetshenziswa kanye nesakhiwo, kukhona uhlobo lwepayipi eliqondile, uhlobo lwentambo, uhlobo lwe-flange, uhlobo lwe-bullet head, uhlobo lwe-epoxy resin encapsulation, uhlobo lwe-lock plate terminal, uhlobo lwe-ABS plastic shell kanye nohlobo lwefilimu ongakhetha kukho. Ngaphezu kwalokho, inkampani yethu inezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, i-thermocouple kanye nenzwa yokushisa ye-infrared.
Q:Ingabe i-temperature sensor yekhampani yenu ikhona esitokweni? Ingabe isekela ukwenziwa ngokwezifiso?
A:Inzwa yokushisa ingeyomkhiqizo othile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liyi-epoxy resin evaliwe, ezinye izinhlobo zimbalwa.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, ama-thermistor okufanele asetshenziswe angakhethwa, futhi ezinye izingxenye ezingenziwa ngokwezifiso zihlanganisa: ubude, usayizi kanye nokuma kwezingxenye zensimbi, uhlobo, ukucaciswa kanye nobude bezintambo, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Q:Uma kungacaci ukuthi yiluphi uhlobo lwe-temperature sensor okufanele isetshenziswe, ingabe inganconywa?
A:Lokhu kunjalo, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacacile, sizoncoma ngokusekelwe esimweni sokusetshenziswa kwekhasimende kanye nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo olithokozisayo. Ngaphezu kwalokho, singakwazi ukulandela izidingo zekhasimende futhi sisebenzisane nekhasimende ekulungiseni ukuklama komkhiqizo, sakhe umkhiqizo owenelisa ikhasimende.
Q:Ingabe ibandakanya imikhiqizo yamandla amasha?
A:Amandla amasha kube yinto edumile eminyakeni yamuva, kufanele abe khona emikhiqizweni yethu. Hhayi nje amandla amasha,Imikhiqizo esetshenziselwa ukuphrinta kwe-3D kanye nezinye izindawo nathi siyayibandakanya, ibanzi kakhulu.

Q: Itafula le-R-T le-NTC thermistor kanye nenzwa yokushisa litholakala kanjani?
A: Yebo, umkhiqizo uzoba netafula le-R-T elihambisanayo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga itafula le-R-T lomkhiqizo ungaxhumana nabantu bakithi ukuze uthole usizo.
Q: Ingabe inkampani yenu ingasiza ekuklameni umkhiqizo nasekudwebeni imidwebo?
A: Kuyenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye zomkhiqizo, okuhlanganisa izinto ezisetshenziswayo, usayizi kanye nezinye izimfuneko ezikhethekile, futhi kudinga nemvume ekhethekile.
