I-NTC & Ama-temperature sensors Q&A
Q:YiniI-NTC thermistor?Yiziphi izinhlobo?
A:Ukwazi ukuthi ukumelana kwe-elekthrikhi kwehle njengoba izinga lokushisa likhuphuka kubizwa ngokuthi ukusebenza kwezinga lokushisa elibi, futhi i-thermistor esetshenziselwa ukumela ukusebenza kwezinga lokushisa elibi ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo oluhlanganiswe nge-glass oluhlangene, uhlobo lwebhola olune-head encane emnyama, uhlobo lwebhola olune-enamel wire, uhlobo lwebhola olune-wire encane yesikhumba, uhlobo lwe-clip-on olune-head encane emnyama, uhlobo lwe-insulating film, diode,Uhlobo lwamandlakanye nama-resistors e-chip.
Q:Yimiphi imingcele yobuchwepheshe ye-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa ngokuthi (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukucaciswa)(1%/3%/5%/10%), isici sokushisa sokumelana (B value) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), izinto eziyisisekelo, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value yinto eyisisekelo sezinto ze-thermistor coefficient (inani lokushisa), elinganiswa ku-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikiswa okuthile. Kukhona kuphela i-B value eyodwa kuwo wonke amafomula kanye nezinga lokushisa lokushisisa. I-B value ye-NTC thermistor ihambisana ngqo ne-temperature coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, kulapho i-temperature coefficient ye-resistance iba nkulu.
Ifomula ye-B value ye-NTC thermistor yile: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, ehlinzekwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu lokusetshenziswa oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B inokumelana okukhulu okushintshayo, okusho ukuthi, lapho inani le-B le-NTC thermistor likhulu, liyazwela kakhulu lapho lisebenzisa, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimiphi imininingwane edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistance oluqinisekisiwe, udinga ukwazisa i-resistance value,i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo; uma uhlobo lungacacile, khona-ke kudingeka ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyinto ehlobene nekhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezimfuno ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa zenkampani yakho? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zokushisa zenkampani yethu zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusetshenziswa kanye nemiqulu ehlukene, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwe-tube eqondile, uhlobo lwe-thread, uhlobo lwe-flange, uhlobo lwe-bullet, uhlobo olufakwe i-epoxy resin, uhlobo lwe-terminal olukhiyayo, uhlobo lwe-ABS plastic housing, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinokunye okufana nezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:Ama-temperature sensors angumkhiqizo othile, futhi izidingo zamakhasimende ahlukahlukene ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingeyohlobo oluhlanganiswe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenza ngokwezifiso, ama-thermistor adingekayo angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nobude bezingxenye zensimbi, izinhlobo zezintambo kanye nobude, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenacaci ukuthi hlobo luni lwe-temperature sensor oluzosetshenziswa, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo onokwaneliseka. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungiswa komkhiqizo ngokuhambisana nezidingo zamakhasimende ukuze senze umkhiqizo onokwaneliseka owudingayo.
Q:Ingabe ihilela imikhiqizo yezimboni ezintsha zamandla?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwaSiphinde sibandakanyeke emikhiqizweni esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene kakhulu.

Q: Ungayithola kanjani i-R-T table ye-NTC thermistor kanye ne-temperature sensor?
A: Yebo, imikhiqizo izoba nethebula le-R-T, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga ithebula le-R-T lomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole ulwazi.
Q: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A: Kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukuhlinzekwa ngemininingwane yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka futhi imvume ekhethekile.
