NTC&Temperature Sensor Q&A
Umbuzo:YiniNTC thermal resistor?Zinezinhlobo eziningani?
Impendulo:I-resistor ehamba phansi njengoba izinga lokushisa lenyuka ibizwa ngokuthi i-negative temperature coefficient, esetshenziselwa ukuveza i-negative temperature coefficient thermal resistor ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zifaka: i-single-ended glass sealed type, i-bead type black head, i-bead type enameled wire, i-bead type leather wire, i-clip type black head, i-insulated film type, diode,Uhlobo lwamandlakanye ne-surface mount resistor.
Q：Yiziphi izipikha zobuchwepheshe ze-NTC thermistor? Sicela unikeze izibonelo.
A：Imininingwane eyinhloko yobuchwepheshe ihlanganisa: inani lokumelana elibizwa ngegama (5K/10K/50K/100K...), ukubekezelelana kokumelana (ukucaciswa)(1%/3%/5%/10%), i-resistor temperature coefficient (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 thermistor?
A：Inani le-B liyisici sezinto (inani lokushisa) lamathisistor we-B, elinganiswa nge-Kelvin (K). I-semiconductor ceramic iyabunjwa ngokushisa okuphezulu bese idlula eziqongweni eziningi ukuze kwakheke i-NTC thermistor chip enokuphikisa okuthile, futhi inani le-B elilodwa kuphela elihambisana nekhethelo ngalinye lokupheka kanye nezinga lokushisa lokupheka. Inani le-B le-NTC thermistor lihambisana ngokuqondile ne-coefficient yokushisa yomkhiqizo, okusho ukuthi, lapho inani le-B likhulu, i-coefficient yokushisa yomkhiqizo 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 emazingeni okushisa angu-T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
I-B value ye-NTC thermal resistor ivamise ukuba phakathi kuka-2000K-6000K, kuye ngokuthi izinhlelo ezahlukene, ungakhetha i-B value ehlukile. Ngokuvamile, njengokulinganisa izinga lokushisa, ukulungisa izinga lokushisa kanye nokunciphisa ukushayisana, ungakhetha i-B value enkulu. Ngoba njengoba izinga lokushisa lishintsha, imikhiqizo enezinga le-B elikhulu ibonisa ukushintsha okukhulu kwe-resistor value, okusho ukuthi i-NTC thermal resistor B value enkulu, ngesikhathi sokusebenzisa ibonakala ikhululekile, isikhathi sokuphendula sisheshisa.
Umbuzo:Uku-odaYiziphi izimfanelo ezidingekayo ze-NTC thermal resistor?
A：Uma kukhona uhlobo lokumelana oluqinisekisiwe, udinga ukwazisa ukumelana, I-B value, ukunemba kanye nobude obudingekayo be-resistor kuphela; uma ungazi uhlobo, kudingeka usebenzise izinga lokushisa, isimo sokusebenzisa kanye ne-resistor value, i-B value, ukunemba kanye nobude obudingekayo be-resistor.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukuphendula?
A：Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyinto ebonisa ikhwalithi. Uma isikhala sensori sincane, ukuphendula kuba kushesha. Isivinini sokuphendula sensori ehlukanisiwe sisheshisa kune sensori efakwe ngaphakathi kwesikhumba sensori esikhumbeni. Isikhathi esijwayelekile sokuphendula se-MF52 uchungechunge lwe-NTC thermal resistor sensor <15 imizuzwana.
Umbuzo:Yiluphi uhlobo lwe-temperature sensor olwenziwa yinkampani yakho? Ziziphi izinhlobo?
Impendulo:Izinzwa zokushisa zenkampani yethu ziningi zazoIzinzwa zokushisa zesitayela se-NTC, ngokwezimo ezahlukene zokusebenzisa kanye nezakhiwo, kunezinketho ezifana nohlobo lwethuluzi eliqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo oluvaliwe nge-epoxy resin, uhlobo lwe-lock washer terminal, uhlobo lwe-ABS plastic shell, kanye nohlobo lwe-film. Ngaphezu kwalokho, inkampani yethu iphinde yaba nezinzwa zokushisa ze-PT100/PT1000, izinzi zokushisa ze-DS18B20, ama-thermocouple, kanye nezinzwa zokushisa ze-infrared.
Umbuzo:Ingabe izithako zakho zokushisa zikhona? Ingabe zixhaswa ngokwezifiso?
Impendulo:Izinzwa zokushisa ziyimikhiqizo ethile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ingeyohlobo oluvaliwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela 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 kungacacile ukuthi iyiphi uhlobo lwesithako sokushisa oludingekayo, kungenzeka yini ukuthi uncoma?
A：Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacile, sincoma ikhasimende ngokusekelwe kusimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole imikhiqizo enelisekile. Ngaphezu kwalokho, singasebenzisana nekhasimende ukuze senze izinguquko ekwakhiweni komkhiqizo ngesikhathi esifanele ngokuya ngezicelo zekhasimende, ukuze senze imikhiqizo enelisekile edingwa yikhasimende.
Umbuzo:Ingabe kukhona imikhiqizo ephathelene namandla amasha?
Impendulo:Amandla amasha kuyinto edumile eminyakeni edlule, kufanele kube khona emikhiqizweni yethu. Akukhona kuphela amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izindawo sikhona, ibanzi kakhulu.

Umbuzo: Ngingayithola kanjani ithebula le-R-T le-NTC thermistor ne-temperature sensor?
A：Yebo, umkhiqizo uzoba ne-R-T ithebula, futhi idatha evela kubakhiqizi abahlukene iyahluka. Uma kudingeka i-R-T ithebula yomkhiqizo, ungaxhumana nabantu bethu bezokuxhumana.
Umbuzo: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A：Yebo, kungenzeka. Imidwebo yemikhiqizo idinga ukuhlinzeka ngemininingwane yezingxenye zomkhiqizo, kuhlanganise nezinto, usayizi kanye nezinye izidingo ezikhethekile, futhi kudingeka ukuthola imvume ekhethekile.
