I-NTC & I-Temperature Sensor Q&A
Umbuzo:YiniI-NTC thermistor?Zikhona izinhlobo eziningaki?
A:Ukwazi ukuthi ukumelana kuyancipha njengoba izinga lokushisa likhuphuka kubizwa ngokuthi isici sokushisa esibi, futhi i-thermistor esetshenziselwa ukubonisa isici sokushisa esibi ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zihlanganisa: uhlobo oluvalwe nge-glass oluhlangene, uhlobo lwebhola elimnyama, uhlobo lwebhola olunezintambo eziboshwe nge-enamel, uhlobo lwebhola olunezintambo ezincane, uhlobo lwebhola oluqinile, uhlobo lwe-film olungavimbeli ukushisa, i-diode,Uhlobo lwamandlakanye nama-resistors e-SMD.
Q:Yimaphi amapharamitha obuchwepheshe we-NTC thermistor? Sicela unikeze izibonelo.
A:Amapharamitha obuchwepheshe abalulekile ahlanganisa: inani lokumelana okubizwa ngegama (5K/10K/50K/100K…), ukubekezelelana kokumelana (ukucaciswa)(1%/3%/5%/10%)、Izinga Lokushisa Lokumelana Nokushisa (Inombolo ye-B) (3270/3380/3435/3470/3950/4000/4050/4500...), uhla lokushisa lokusebenza (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…) , Izinga lezinto, isikhathi sokuphendula…
Q:YiniInani le-B le-NTC thermistor?
A:Inani le-B liyisilinganiso sezinto ze-thermistor coefficient coefficient (inani lokushisa), elingakaniswa ku-Kelvin (K). I-ceramic ye-semiconductor iyaboshwa ngezinga lokushisa eliphezulu bese idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokumelana okuthile. Kukhona kuphela inani le-B elilodwa kuwo wonke amafomula kanye nezinga lokushisa lokuboshwa. Inani le-B le-NTC thermistor liyalingana nenani lokumelana lokushisa lomkhiqizo, okusho ukuthi, lapho inani le-B likhulu, kulapho inani lokumelana lokushisa likhulu khona.
Ifomula yenombolo ye-B ye-NTC thermistor yile: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: inombolo ye-B ye-NTC thermistor, ehlinzekwa umkhiqizi; i-RT1, i-RT2: amanani okumelana ne-thermistor ezingeni lokushisa elingu-T1, T2 ngokulandelana; i-T1, T2: isikali sokushisa esingenamkhawulo.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu lokusebenza oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, umkhiqizo onenani elikhulu le-B uzoba nokushintsha okukhulu kwenani lokumelana, okungukuthi, lapho inani le-NTC thermistor B likhulu, liyoba lisebenza kakhudlwana lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYimiphi idatha edingekayo lapho udinga i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistor oluqinisekisiwe, udinga ukwazisa inani lokumelana, Inani le-B, ukunemba, kanye nobude obudingekayo be-resistor; uma ungacaciswanga ngohlobo, kuzodingeka usebenzise izinga lokushisa, isimo sokusetshenziswa, inani lokumelana, inani le-B, ukunemba, kanye nobude obudingekayo be-resistor.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengesikhathi sokufinyelelaIsikhathi esidingekayo ukufinyelela ku-62% noma izinga lokushisa elisha, futhi kuncike kwikhwalithi. Uma inzwa incane, iyashesha ukusabela. Izinzwa ezihlukene ziyashesha ukusabela kunezinzwa ezifanayo ezigoqwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
Q:Uhlobo luni lwe-sensor yakho yobushushu? Zikhona izinhlobo eziningaki?
Impendulo:I-sensor yethu yobushushu ingeyonaIzinzwa zokushisa ezinhlobo ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, zitholakala ngezinhlobo ezilandelayo: uhlobo oluqondile, uhlobo olune-thread, uhlobo olune-flange, uhlobo lwebhola, uhlobo olugoqwe nge-epoxy, uhlobo lwe-lock washer terminal, uhlobo lwe-ABS plastic casing, kanye nohlobo oluyicwecwe. Ngaphezu kwalokho, sinikeza nezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, nezinzwa zokushisa ze-infrared.
Q:Ingabe i-sensor yakho yobushushu iyatholakala esitokweni? Ingabe isekela ukwenziwa ngokwezifiso?
Impendulo:I-sensor yobushushu ingumkhiqizo othile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esiyinayo isendlini ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso. Ama-thermistor adingekayo angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nobukhulu bezingxenye zensimbi, imodeli, imininingwane nobude bezintambo, kanye nokukhethwa kwezinhlobo ezahlukene zama-connectors.
Umbuzo:Uma kungenacaci ukuthi hlobo luni lwe-temperature sensor oludingekayo, ungakwazi ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingaqinisekile, sincoma ikhasimende ngokusekelwe endaweni yokusebenzisa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa imikhiqizo ngokuvumelana nezicelo zamakhasimende ngesikhathi, ukuze senze imikhiqizo eyanele edingwa ngamakhasimende.
Umbuzo:Ingabe kukhona imikhiqizo ehlobene namandla amasha?
A:Amandla avuselelekayo ayinto ethandwayo eminyakeni yamuva nje, futhi kufanele ibe khona emikhiqizweni yethu. Akuyona nje amandla avuselelekayo, kodwaSiphinde sisebenze nemikhiqizo esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene.

Umbuzo: Ungayithola kanjani ithebula le-R-T le-NTC thermistor ne-temperature sensor?
Impendulo: Yebo, imikhiqizo izoba nethebula le-R-T, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga ithebula le-R-T lomkhiqizo, ungaxhumana nabasebenzi bethu.
Q: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A: Kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukuhlinzeka ngedatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
