I-NTC & inzwa yokushisa Imibuzo Nezimpendulo
Q：YiniNTC thermistor?Yiziphi izinhlobo ezikhona?
Impendulo:Isici sokwehla kwe-resistance 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 enekhanda elincane elimnyama, uhlobo lwe-bead enamacwecwe e-copper, uhlobo lwe-bead enentambo encane yesikhumba, uhlobo lwe-card-point enekhanda elincane elimnyama, uhlobo lwe-insulating film, i-diode、uhlobo lwamandlakanye ne-chip resistor.
Umbuzo:Yimiphi imingcele yobuchwepheshe ye-NTC thermistor? Sicela unikeze izibonelo.
Impendulo:Imingcele yobuchwepheshe eyinhloko ifaka: inani lokumelana elijwayelekile (5K/10K/50K/100K…), ukubekezelelana kwesilinganiso sokumelana (ukunemba)(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:KuyiniI-B value ye-NTC thermistor?
Impendulo:I-B value iyisici esingaguquki sezinto (i-thermal index) se-thermistor yokushisa, iyunithi yi-Kelvin temperature (K). I-semiconductor ceramic ngemva kokushiswa ezingeni lokushisa eliphezulu ngokusebenzisa uchungechunge lwezinqubo zokucubungula yakha i-NTC thermistor chip enesilinganiso esithile sokumelana, inhlanganisela ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. I-B value ye-NTC thermistor ihlobene ngqo ne-coefficient yokushisa yokumelana yomkhiqizo, 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 le-resistance ye-thermistor lapho izinga lokushisa kungu-T1、T2 ngokulandelana; T1、T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K no-6000K, kuye ngokwesimo sokusetshenziswa okuhlukene kungakhethwa inani le-B elihlukile. Ngokuvamile njengomkhiqizo wokulinganisa izinga lokushisa, isinxephezelo sezinga lokushisa kanye nokuvimbela i-surge, kungakhethwa inani le-B elikhulu. 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, futhi isikhathi sokuphendula siyashesha.
Q：Uku-odaYimiphi idatha okufanele inikezwe uma kudingeka i-NTC thermistor?
A:Uma kunohlobo lokumelana oseluvele lunqunyiwe, kudingeka kwaziswe inani lokumelana,I-B value, ukunemba kanye nobude bokumelana okudingekayo kuphela; uma ungazi uhlobo, kudingeka ukushisa okusetshenziswayo, isimo sokusetshenziswa kanye nenani lokumelana, i-B value, ukunemba kanye nobude bokumelana okudingekayo.
Q：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 kunezwa efanayo epakishwe ngaphakathi kwegobolondo lensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
Umbuzo:Ama-temperature sensor enkampani yenu yiluphi uhlobo lwama-temperature sensor? Yiziphi izinhlobo ezikhona?
A:Ama-temperature sensor enkampani yethu amaningi angaphansi kwe-I-NTC temperature sensor, ngokuya ngesimo lapho isetshenziswa khona 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 shell kanye nohlobo lwefilimu ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu iphinde ibe nama-PT100/PT1000 temperature sensor, ama-DS18B20 temperature sensor, ama-thermocouple kanye nama-infrared temperature sensor.
Umbuzo:Ingabe ama-temperature sensor enkampani yenu akhona esitokweni? Ingabe niyawasekela ukwenziwa ngendlela eyodwa?
A：Inzwa yokushisa ingumkhiqizo okhethekile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liwuhlobo oluvalwe nge-epoxy resin, ezinye izinhlobo zimbalwa.
Imikhiqizo yethu isekela ukwenziwa ngendlela eyodwa, ama-thermistor okufanele asetshenziswe angakhethwa, ngaphezu kwalokho izingxenye ezingenziwa ngendlela eyodwa zihlanganisa: ubude nobukhulu kanye nokuma kwezingxenye zensimbi, uhlobo lwezingcingo kanye nobude bazo, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Q：Uma kungacaci ukuthi hlobo luni lwenzwa yokushisa okufanele isetshenziswe, ingabe kungenziwa isincomo?
A：Lokhu kunjalo, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacaci, sizoncoma ngokusekelwe esimweni sokusetshenziswa kwekhasimende nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi ukulandela izidingo zekhasimende futhi sisize ikhasimende ngokushesha ekulungiseni ukwakheka komkhiqizo, senze umkhiqizo okhethekile ozokwanelisa ikhasimende.
Q：Ingabe kukhona imikhiqizo ehlobene namandla amasha?
Impendulo:Amandla amasha abe yinto edumile eminyakeni yamuva, kufanele abe khona emikhiqizweni yethu. Hhayi nje amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo nathi siyayisebenza, isabalele kakhulu.

Umbuzo: Ithebula le-R-T le-NTC thermistor nenzwa yokushisa litholakala kanjani?
A：Yebo, umkhiqizo uzoba ne-R-T table ehambisana nawo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga i-R-T table eqondene nomkhiqizo ungaxhumana nabasebenzi benkampani yethu ukuze uthole usizo.
Q：Ingabe inkampani yenu 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.
