I-NTC & Inzwa yokushisa Imibuzo Nezimpendulo
Umbuzo:YiniNTC thermistor?Yiziphi izinhlobo ezikhona?
Impendulo:Isimo sokwehla kwe-resistance njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici se-negative temperature, futhi i-thermistor esetshenziselwa ukukhombisa isici se-negative temperature ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zifaka: uhlobo lwe-single-end glass seal, uhlobo lwe-bead elinekhanda elincane elimnyama, uhlobo lwe-bead enamacwecwe e-copper, uhlobo lwe-bead eline-wire encane yesikhumba, uhlobo lwe-card-point black head, uhlobo lwe-insulating film, i-diode,Uhlobo lwamandlaKanye ne-chip resistor.
Umbuzo:Yiziphi izici zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
Impendulo:Imingcele yobuchwepheshe eyinhloko ihlanganisa: inani lokumelana elijwayelekile (5K/10K/50K/100K…), ukubekezelelana kwesilinganiso sokumelana (ukucaca)(1%/3%/5%/10%), i-coefficient yokushisa kwe-resistance (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), ububanzi bokushisa okusebenzayo (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), i-material constant, i-time constant…
Umbuzo:KuyiniInani le-B le-NTC thermistor?
Impendulo:Inani le-B liyinto engaguquki yezinto ze-thermistor ye-temperature coefficient (i-thermal index), iyunithi yi-Kelvin temperature (K). I-semiconductor ceramic ngemuva kokushiswa okushisa okuphezulu ngokusebenzisa uchungechunge lwezinqubo zokucubungula yakha i-NTC thermistor chip ene-resistivity ethile, ifomula ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. Inani le-B le-NTC thermistor lihlobene ngqo ne-temperature coefficient yokumelana yomkhiqizo, okusho ukuthi uma inani le-B likhulu, i-temperature coefficient 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 le-resistance le-thermistor lapho izinga lokushisa lingama-T1, T2; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K no-6000K, kuye ngokusetshenziswa okuhlukene kungakhethwa inani le-B elihlukile. Ngokuvamile njengomkhiqizo wokulinganisa izinga lokushisa, isinxephezelo sokushisa kanye nokuvimbela i-surge, kungakhethwa inani le-B elikhulu. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo onenani elikhulu le-B ushintsha kakhulu kunani lawo okumelana nawo, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYiluphi ulwazi okufanele lunikezwe uma kusetshenziswa i-NTC thermistor?
A:Uma kunohlobo lokumelana oseluvele lunqunyiwe, kudingeka kwaziswe inani lokumelana,Inani le-B, ukucaca kanye nobude bokumelana okudingekayo; uma ungazi uhlobo, kudingeka ukushisa okusetshenziswayo, indawo yokusetshenziswa kanye nenani lokumelana, inani le-B, ukucaca kanye nobude bokumelana okudingekayo.
Umbuzo:Isivinini sokuphendula se-NTC thermistor sishesha kangakanani?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo ekushiseni okusha, futhi kungumsebenzi wekhwalithi. Uma inzwa incane, isabela ngokushesha. Izinzwa ezihlukene zisabela ngokushesha kunezinto ezifanayo ezifakwe ngaphakathi kwekhabethe lensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
Umbuzo:Ama-temperature sensor enkampani yakho ayiluphi uhlobo lwe-temperature sensor? Yiziphi izinhlobo ezikhona?
A:Ama-temperature sensor enkampani yethu amaningi angaphansi kwe-I-NTC temperature sensor, kuye ngendawo yokusetshenziswa kanye nesakhiwo, kukhona uhlobo lwepayipi eliqondile, uhlobo olunentambo, uhlobo lwe-flange, uhlobo lwekhanda lesibhamu, uhlobo olufakwe nge-epoxy resin, uhlobo lwe-lock terminal, uhlobo lwe-ABS plastic housing kanye nohlobo lwefilimu ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu inama-PT100/PT1000 temperature sensor, ama-DS18B20 temperature sensor, ama-thermocouple kanye nama-infrared temperature sensor.
Umbuzo:Ingabe ama-temperature sensor enkampani yakho akhona esitokweni? Ingabe asekela ukwenziwa ngendlela oyifunayo?
A:Inzwa yokushisa iyingxenye yomkhiqizo othile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liyi-epoxy resin seal type, ezinye izinhlobo zincane.
Imikhiqizo yethu isekela ukwenziwa ngendlela oyifunayo, ama-thermistor okufanele asetshenziswe angakhethwa, futhi ezinye izingxenye ezingenziwa ngendlela oyifunayo zihlanganisa: ubude, usayizi kanye nokuma kwezingxenye zensimbi, uhlobo, ukucaciswa kanye nobude kwezintambo, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Umbuzo:Uma kungacaci ukuthi yiluphi uhlobo lwenzwa yokushisa okufanele isetshenziswe, ingabe kungenziwa isincomo?
A:Lokhu kunjalo, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacaci, sizoncoma ikhasimende ngokusekelwe endaweni yokusetshenziswa kanye nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owenelisayo. Ngaphezu kwalokho, singakwazi ukulungisa ukwakheka komkhiqizo ngokushesha ngokuhambisana nezidingo zekhasimende, sakhe umkhiqizo owenelisayo odingwa yikhasimende.
Umbuzo:Ingabe kukhona imikhiqizo ehlobene namandla amasha?
Impendulo:Amandla amasha bekuyinto edumile eminyakeni yamuva, kufanele kube khona emikhiqizweni yethu. Hhayi nje amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayisebenza, ibanzi kakhulu.

Umbuzo: Ithebula le-R-T le-NTC thermistor kanye nenzwa yokushisa litholakala kanjani?
A: Yebo, umkhiqizo uzoba netafula le-R-T elihambisana nawo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga itafula le-R-T eliqondene nomkhiqizo, ungaxhumana nabasebenzi benkampani yethu ukuze uthole usizo.
Umbuzo: Ingabe inkampani yakho ingasiza ekuklameni umkhiqizo nasekudwebeni imidwebo?
Impendulo: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye zomkhiqizo, okuhlanganisa into, usayizi nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
