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:Yimiphi imingcele yobuchwepheshe ye-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukucaciswa)(1%/3%/5%/10%), i-coefficient yokushisa yokumelana (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…), i-constant yempahla, i-constant yesikhathi…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-temperature (thermal index), eyi-unit ye-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 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 oluhlukile lwezicelo. 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 inokushintsha okukhulu ekumeleni kwayo, okusho ukuthi, lapho 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, kudingeka ukuthi kushiwo i-resistance value,i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo; uma uhlobo lungacaciswa, khona-ke kudingeka ukushisa, 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 kuyisici sekhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi esijwayelekile sokuphendula se-MF52 series NTC thermistor sensors singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa ezisetshenziswa yinkampani yakho? Yiziphi izinhlobo ezikhona?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiklamo ehlukene, kunezinhlobo ezilandelayo ezitholakalayo: uhlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo olufakwe i-epoxy, uhlobo lwe-terminal yokukhiya, uhlobo lwe-ABS plastic housing, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinikeza nezinzwa zokushisa ze-PT100/PT1000, izinzwa 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, imodeli, imininingwane nobude bezintambo, kanye nokukhethwa kwezinhlobo ezahlukene zama-connectors.
Q:Uma kungenacaci ukuthi hlobo luni lwe-temperature sensor oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezahlukahlukene, lapho ikhasimende lingacacisi, 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 kukhona imikhiqizo ehlobene namandla amasha?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Hhayi amandla amasha kuphela, kodwaSiphinde sibandakanyeke emikhiqizweni esetshenziswa ku-3D printing kanye nezinye izindawo, futhi ububanzi buyabheka.

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.
