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 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 (°C) (-30°C-105°C/-30°C-125°C/-40°C-250°C…), isici sezinto, isikhathi sokudlula…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sokushisa kwe-thermistor (inani le-thermal), elingakaniswa 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 ngokuqondile ne-temperature coefficient yokumelana komkhiqizo, okusho ukuthi, lapho i-B value ikhulu, i-temperature coefficient yokumelana nayo iba nkulu.
Ifomula ye-B value ye-NTC thermistor ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor lapho izinga lokushisa lingama-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha amanani ahlukene e-B ngokuya ngezindawo ezahlukene zokusebenzisa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokuvimbela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B ibonisa ukushintsha okukhulu ekumeleni, okusho ukuthi, uma 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 oluqinisekisiwe lwe-resistance, udinga ukwazisa i-resistance, i-B value, ukucaciswa, kanye nobude be-resistance obudingekayo; uma uhlobo lungacacile, khona-ke kudingeka ukushisa, indawo yokusetshenziswa, kanye ne-resistance, 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 kuncike kwikhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezimiso ze-MF52 NTC thermistor singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa ezisetshenziswa yinkampani yakho? Ziziphi izinhlobo?
A:Iningi lezinzwa zethu zokushisa zingezakhoIzinzwa zokushisa zesitayela se-NTC, ngokuya ngezimo zokusetshenziswa kanye nemiqulu ehlukene, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lweshubhu eqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo lokufakwa kwe-epoxy, uhlobo lwe-terminal lokukhiya, uhlobo lwe-ABS plastic casing, kanye nohlobo lwe-film. Ngaphezu kwalokho, sinezinzwa 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, 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 oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezahlukahlukene, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe endaweni yokusetshenziswa yekhasimende nezidingo ezithile, ukuze ikhasimende lithole umkhiqizo onelisekayo. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungiswa komkhiqizo ngokuhambisana nezidingo zamakhasimende ukuze senze umkhiqizo onelisekayo owudingayo ikhasimende.
Q:Ingabe ihilelekile emikhiqizweni yezintsha 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 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.
