I-NTC & i-temperature sensor Q&A
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 ezivamile zifaka: uhlobo lwe-single-end glass seal, uhlobo lwe-bead black head encane, uhlobo lwe-bead enameled wire, uhlobo lwe-bead皮 wire encane, uhlobo lwe-card point black head encane, 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 kokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…)、i-material constant、i-time constant…
Umbuzo:KuyiniI-B value ye-NTC thermistor?
Impendulo:I-B value iyisici sezinto se-temperature coefficient thermistor (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 ngqo 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 lingama-T1、T2; T1、T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, kuye ngokwesikhathi 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 le-B elikhulu 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 ukumelana,I-B value, ukunemba kanye nobude bokumelana okudingekayo kuphela; uma ungazi uhlobo, kudingeka ukushisa okusetshenziswayo, indawo yokusetshenziswa kanye nokumelana, 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 efakwe 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, ngokuya ngesimo sokusetshenziswa 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 ezingakhethwa. 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 eyodwa?
A：I-temperature sensor iyingxenye yomkhiqizo othile, izidingo zamakhasimende ahlukene ziyahluka, imikhiqizo ekhona manje iningi liyi-epoxy resin sealed type, ezinye izinhlobo zincane.
Imikhiqizo yethu isekela ukwenziwa ngendlela eyodwa, ama-thermistor okufanele asetshenziswe angakhethwa, ngaphezu kwalokho izingxenye ezingenziwa ngendlela eyodwa zihlanganisa: ubude nobukhulu nokuma kwezingxenye zensimbi, uhlobo lwezintambo nokucaciswa nobude, kanye nokukhetha izinhlobo ezahlukene zama-connector.
Q：Uma kungacaci ukuthi yiluphi uhlobo lwe-temperature sensor okufanele isetshenziswe, ingabe kungenziwa isincomo?
A：Lokhu kunjalo, ngoba izinhlobo zokuxhumana ziningi, uma ikhasimende lingacaci, sizoncoma ngokusekelwe endaweni yokusetshenziswa kwekhasimende kanye nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi ukulungisa ukwakheka komkhiqizo ngokushesha ngokuhambisana nezidingo zekhasimende, senze umkhiqizo owanelisayo odingwa yikhasimende.
Q：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 siyayihlinzeka, ibanzi kakhulu.

Umbuzo: I-R-T table ye-NTC thermistor ne-temperature sensor itholakala kanjani?
A：Yebo, imikhiqizo izoba ne-R-T table ehambisanayo, 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 imikhiqizo nasekudwebeni imidwebo?
Impendulo: Yebo kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu kanye nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
