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 isici esibi sokushisa, futhi i-thermistor esetshenziselwa ukumela lesi sici esibi sokushisa 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, i-diode,Uhlobo lwamandlakanye nama-resistors e-chip.
Q:Yimaphi amaparamitha ezobuchwepheshe e-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukucaciswa)(1%/3%/5%/10%), isici sokushisa sokumelana (inani le-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…), izinto eziyinhlanganisela, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value yinto engapheli yezinto ezishisayo (i-thermal index), eyenziwa nge-Kelvin temperature (K). I-semiconductor ceramic, ngemva kokushiswa ezingeni lokushisa eliphezulu, idlula uchungechunge lwezinqubo zokucubungula ukuze yakhe i-NTC thermistor chip enokuphikiswa okuthile. I-B value eyodwa kuphela ekhona nge-formula ngayinye kanye nezinga lokushisa lokushiswa. I-B value ye-NTC thermistor ihambisana ngqo ne-temperature coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, i-temperature coefficient ye-resistance nayo 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, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa elingu-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, okusho ukuthi, uma inani le-B le-NTC thermistor likhulu, liyazwela kakhulu lapho lisetshenziswa, 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 ungacaciswanga ngohlobo, khona-ke udinga 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 njengesikhathi sokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi esivamile sokuphendula se-MF52 series NTC thermistor sensors singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa enizisebenzisayo? Yiziphi izinhlobo ezikhona?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiklamo ehlukene, zineziqhakulo ezilandelayo ongakhetha kuzo: uhlobo lwethiphu eqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-terminal olukhiyayo, uhlobo lwe-ABS plastic shell, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinezinzwa zokushisa ze-PT100/PT1000, izinziwa zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Q:Ingabe izinzwa zakho zokushisa zikhona esitokweni? Ingabe ziyasekelwa ngokwezifiso?
A:I-temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingohlobo oluhlanganiswe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, futhi ama-thermistor adingekayo angakhethwa. Ngaphezu kwalokho, izingxenye ezingenziwa ngokwezifiso zihlanganisa: ubude nobude bezingxenye zensimbi, izinhlobo zezintambo kanye nobude, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenjalo kucacile ukuthi yiluphi uhlobo 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 onelisekayo. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa imidwebo yomkhiqizo ngesikhathi ngokuya ngezidingo zamakhasimende, ukuze senze umkhiqizo onelisekayo owudingayo ikhasimende.
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 ububanzi buyimpawu.

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 imvume ekhethekile.
