I-NTC & I-Temperature Sensor Q&A
Umbuzo:YiniI-NTC thermistor?Ziziphi izinhlobo?
Impendulo:Ubudleli lapho ukumelana kwehlela njengoba izinga lokushisa likhuphuka libizwa ngokuthi i-negative temperature characteristic, futhi i-thermistor esetshenziselwa ukubonisa i-negative temperature characteristic ibizwa ngokuthiI-NTC thermal resistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezijwayelekile zihlanganisa: uhlobo olulodwa lwe-glass-sealed, uhlobo lwebhola elimnyama elincane, uhlobo lwebhola eline-enamel wire, uhlobo lwebhola eline-plastic wire encane, uhlobo lwebhola elincane elincane, uhlobo lwe-insulating film, i-diode,Uhlobo lwamandlakanye ne-surface mount resistor.
Q:Yiziphi izipikha zobuchwepheshe ze-NTC thermal resistor? Sicela unikeze izibonelo.
A:Ipharamitha yobuchwepheshe eyinhloko ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kokumelana (ukucaciswa)(1%/3%/5%/10%), i-temperature coefficient yokumelana (i-B value) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃)…), isici sezinto, isici sesikhathi...
Q:YiniInani le-B le-NTC thermal resistor?
A:Inani le-B liyisici sezinto (inani le-thermal) samathisistor we-B, elinganiswa nge-Kelvin (K). I-semiconductor ceramic iyabunjwa ngokushisa okuphezulu bese idlula eziqongweni eziningi ukuze kwakheke i-NTC thermal chip enokuphikisa okuthile, futhi inani elilodwa kuphela le-B elitholakala nge-formula ngayinye nokushisa kokushisa. Inani le-B le-NTC thermal resistor liyalingana nokuphikisa kwe-thermal ye-thermal resistor, okusho ukuthi, lapho inani le-B likhulu, kulapho ukuphikisa kwe-thermal ye-thermal resistor kukhulu.
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; i-RT1, RT2: amanani okumelana kwe-thermistor emazingeni okushisa angu-T1, T2 ngokulandelana; i-T1, T2: isikali sokushisa esiphelele.
I-B value ye-NTC thermistor ngokuvamile isuka ku-2000K iye ku-6000K, futhi ungakhetha i-B value ehlukile ngokuya ngesimo sokusetshenziswa. Ngokuvamile, imikhiqizo esetshenziselwa ukukala izinga lokushisa, ukulungisa izinga lokushisa, kanye nokuvimbela ukwanda kungasebenzisa i-B value enkulu. Ngoba njengoba izinga lokushisa lishintsha, ukumelana komkhiqizo onama-B value amakhulu kuhluka kakhulu, okusho ukuthi, lapho i-B value ye-NTC thermistor inkulu, iyazwela kakhulu lapho isetshenziswa, futhi isikhathi sokuphendula siyashesha.
Umbuzo:Uku-odaYimaphi idatha edingekayo lapho usebenzisa i-NTC thermistor?
A:Uma kukhona uhlobo oluqinisekisiwe lokumelana, udinga ukwazisa ukumelana, I-B value, ukunemba, kanye nobude obudingekayo bezintambo; uma ungacaciswanga ngohlobo, kudingeka ukushisa, isimo sokusetshenziswa, kanye nenani lokumelana, i-B value, ukunemba, kanye nobude obudingekayo bezintambo.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukuphendula?
A:Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyimfuneko yekhwalithi. Lapho inzwa incane, iyashesha ukusabela. Izinzwa ezihlukene zisabela ngokushesha kunezinzwa ezifanayo ezigoqwe ezindlini zensimbi. Isikhathi sokuphendula esijwayelekile sezimiso ze-MF52 NTC thermistor sensor singaphansi kwemizuzwana engu-15.
Umbuzo:Yiluphi uhlobo lwe-temperature sensor olwenziwa yinkampani yakho? Yiziphi izinhlobo ezikhona?
Impendulo:Izinzwa zokushisa zenkampani yethu ziningi kakhuluIzinzwa zokushisa zesitayela se-NTC, ngokwezimo ezahlukene zokusebenzisa kanye nezakhiwo, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo oluvaliwe lwe-epoxy resin, uhlobo lwesiphetho sokukhiya, uhlobo lwekhava ye-ABS plastic, kanye nohlobo lwe-film. Ngaphezu kwalokho, inkampani yethu nayo inezinzwa zokushisa ze-PT100/PT1000, izinzi zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Umbuzo:Ingabe izinzwa zokushisa zenkampani yakho zikhona esitokweni? Ingabe isekela ukwenziwa ngokwezifiso?
Impendulo:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ingeyohlobo oluvaliwe lwe-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu ixhasa ukwenziwa ngokwezifiso, ama-thermistor asetshenzisiwe angakhethwa, futhi izinto ezingenziwa ngokwezifiso zihlanganisa: ubude nosayizi wezingxenye zensimbi, imodeli, imininingwane, nobude bezintambo, kanye nokukhetha izinhlobo ezahlukene zokuxhuma.
Umbuzo:Uma kungenacaci ukuthi hlobo luni lwe-temperature sensor oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe esimweni sokusetshenziswa kwamakhasimende nezidingo ezithile, ukuze amakhasimende athole imikhiqizo enelisekile. Ngaphezu kwalokho, singasebenzisana namakhasimende ukulungisa ukuklama komkhiqizo ngesikhathi ngokwemibandela yekhasimende, ukuze senze imikhiqizo enelisekile edingwa ngamakhasimende.
Umbuzo:Ingabe kukhona imikhiqizo ehlobene namandla avuselelekayo?
Impendulo:Amandla avuselelekayo ayinto ethandwayo eminyakeni yamuva nje, futhi kumele ibe khona emikhiqizweni yethu. Akuyona nje amandla avuselelekayo, kodwa futhiSiphinde sibe nemikhiqizo esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene kakhulu.

Umbuzo: Ngingayithola kanjani ithebula le-R-T le-NTC thermistor ne-temperature sensor?
A: Yebo, umkhiqizo uzoba ne-R-T table ehambisanayo, futhi idatha evela kubakhiqizi abahlukene ihlukile. Uma udinga i-R-T table yomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole usizo.
Umbuzo: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A: Yebo. Ukudweba imidwebo yomkhiqizo kudinga idatha yazo zonke izingxenye zomkhiqizo, okuhlanganisa izinto, ubukhulu, nezinye izidingo ezikhethekile, futhi kudingeka imvume ekhethekile.
