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-enamel, uhlobo lwe-bead elocingo oluncane lwesikhumba, uhlobo lwe-card-point black head, 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 ihlanganisa: 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 ze-thermistor ye-temperature coefficient (i-thermal index), iyunithi yi-Kelvin temperature (K). I-semiconductor ceramic ngemuva kokushiswa ngezinga lokushisa eliphezulu ngokusebenzisa uchungechunge lwezinqubo zokucubungula yakha i-NTC thermistor chip ene-resistivity ethile, ifomula ngayinye kanye nezinga lokushisa lokushisa kunenani elilodwa le-B. I-B value ye-NTC thermistor ihlobene kahle ne-temperature coefficient yokumelana yomkhiqizo, okusho ukuthi uma i-B value inkulu, 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 ye-thermistor lapho izinga lokushisa kungu-T1 no-T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, kuye ngokwesimo esihlukile sokusetshenziswa 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 kunani lawo lokumelana, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela kakhulu, futhi isikhathi sokuphendula siyashesha.
Umbuzo: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.
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 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 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 lwe-bullet head, uhlobo olufakwe nge-epoxy resin, uhlobo lwe-lock terminal, uhlobo lwe-ABS plastic shell 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 yenu akhona esitokweni? Ingabe niyawasekela ukwenziwa ngendlela oyifunayo?
Impendulo:Inzwa yokushisa iyingxenye yomkhiqizo othile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liwuhlobo oluvalwe nge-epoxy resin, ezinye izinhlobo zincane.
Imikhiqizo yethu isekela ukwenziwa ngendlela oyifunayo, ama-thermistor okufanele asetshenziswe angakhethwa, ngaphezu kwalokho izingxenye ezingenziwa ngendlela oyifunayo zihlanganisa: ubude nosayizi kanye nokuma kwezingxenye zensimbi, uhlobo lwezingcingo kanye nobude bazo, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Umbuzo:Uma kungacaci ukuthi hlobo luni lwenzwa yokushisa okufanele isetshenziswe, ingabe kungcono kunconywe?
A:Lokhu impela, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacaci, sizoncoma ngokusekelwe esimweni sokusetshenziswa kwekhasimende nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi futhi ukulandela izidingo zekhasimende futhi sisize ikhasimende ngokushesha ekulungiseni ukwakheka komkhiqizo, senze 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, isabalele kakhulu.

Umbuzo: I-R-T table ye-NTC thermistor kanye nenzwa yokushisa itholakala kanjani?
Impendulo: 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.
Umbuzo: Ingabe inkampani yenu ingasiza ekuklameni umkhiqizo nasekudwebeni imidwebo?
Impendulo: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye ezahlukene zomkhiqizo, okuhlanganisa into, usayizi nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
