I-NTC & Ama-temperature sensors Q&A
Q:YiniAma-NTC thermistor?Yiziphi izinhlobo?
A:Ukwelashwa lapho i-resistance yehla njengoba izinga lokushisa likhuphuka libizwa nge-negative temperature characteristic, futhi i-thermistor ekhombisa le-negative temperature characteristic ibizwa nge-I-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo oluvalwe nge-glass oluhlangothini olulodwa, uhlobo lwebhola olune-head encane emnyama, uhlobo lwebhola olune-enamel wire, uhlobo lwebhola olune-plastic wire encane, uhlobo lwe-clip-on olune-head encane emnyama, uhlobo lwe-insulating film, i-diode,Uhlobo lwamandlakanye nama-resistors e-SMD.
Q:Yimaphi amaparamitha ezobuchwepheshe e-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukunemba)(1%/3%/5%/10%), coefficient yokushisa kokuphikisa (B value) (3270/3380/3435/3470/3950/4000/4050/4500…) , uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), constants yezinto, constants yesikhathi…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sokushisa kwe-thermistor (index yokushisa), eyi-unit ye-Kelvin temperature (K). I-NTC thermistor chip enokumelana okuthile kwe-resistivity yenziwa ngokuhlanganisa i-ceramic ye-semiconductor ezingeni lokushisa eliphezulu ngokusebenzisa izinqubo eziningi zokucubungula. Kukhona i-B value eyodwa kuphela nge-formula ngayinye kanye nezinga lokushisa lokuhlanganisa. I-B value ye-NTC thermistor ihambisana ngokuqondile 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 ithi: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, enikezwa umkhiqizi; RT1, RT2: amanani okuphikisa e-thermistor emazingeni okushisa angu-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lisuka ku-2000K liye ku-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu lokusebenza oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukukhokhela izinga lokushisa, nokuvimbela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B ibonisa ushintsho olukhulu ekumeleni, okungukuthi, lapho inani le-B le-NTC thermistor likhulu, liyazwela kakhudlwana lapho lisetshenziswa, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimaphi idatha edingekayo lapho u-oda i-NTC thermistor?
A:Uma uhlobo lwe-resistance selulungisiwe, udinga ukucacisa i-resistance value,i-B value, ukunemba, kanye nobude be-resistance obudingekayo; uma ungacaciswanga ngohlobo, khona-ke udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukunemba, kanye nobude be-resistance obudingekayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuncike kukhwalithi. Uma inzwa incane, iyashesha ukuphendula. Izinzwa ezihlukene ziphendula ngokushesha kunezinzwa ezifanayo ezifakwe ezindlini zensimbi. Isikhathi esivamile sokuphendula sezimiso ze-MF52 NTC thermistor singaphansi kwemizuzwana engu-15.
Q:Yiluphi uhlobo lwezinzwa zokushisa zenkampani yakho? Yiziphi izinhlobo ezikhona?
A:Izinsizwa zokushisa zenkampani yethu ziningi.Izinzwa zokushisa zesistimu ye-NTC, ngokuya ngezimo zokusebenzisa kanye nokwakheka, kunezinhlobo ezifana ne-straight tube, i-threaded, i-flange, i-bullet head, i-epoxy encapsulated, i-lock washer terminal, i-ABS plastic shell, kanye ne-thin film ongakhetha kuzo. Ngaphezu kwalokho, sinezinzwa 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 ukwenziwa ngokwezifiso?
A:I-temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu iyasekelwa ukwenziwa ngokwezifiso, ama-thermistor adingekayo angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nosayizi wezingxenye zensimbi, izinhlobo zezintambo, ubude, kanye nokukhethwa kwezinhlobo ezahlukene zokuxhuma.
Q:Uma kungenjalo ukuthi uhlobo lwe-temperature sensor oluzosetshenziswa lungacaci, ingabe kungenzeka ukuncoma?
A:Impela, ngoba sibhekana nezinhlobo eziningi, lapho ikhasimende lingacacile, sincoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa ukuklama komkhiqizo ngesikhathi ngokwezidingo zamakhasimende, ukuze senze umkhiqizo owanele owudingayo ikhasimende.
Q:Ingabe kukhona imikhiqizo ehlobene namandla amasha?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwa futhiSiphinde sisebenze nemikhiqizo esetshenziswa ku-3D printing kanye nezinye izindawo, ezibanzi kakhulu.

Q: Ungayithola kanjani ithebula le-R-T le-NTC thermistor kanye ne-temperature sensor?
A: Yebo, umkhiqizo uzoba 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: Yebo, kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukuhlinzekwa ngemininingwane yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
