NTC& sensor yokushisa Q&A
Umbuzo:YiniNTC thermal resistor?Ziziphi izinhlobo?
Impendulo:I-resistor ye-thermal ehlobene nokwanda kokushisa ibizwa ngokuthi i-negative temperature coefficient, esetshenziselwa ukuveza izici ze-negative temperature coefficient ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zikhona: i-single-ended glass-sealed type, i-bead type black head, i-bead type enephepha, i-bead type leather wire, i-clip type black head, i-insulated film type, i-diode,Uhlobo lwamandlafuthi i-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 enokuphikiswa okuthile, futhi inani elilodwa kuphela le-B elitholakala nge-formula ngayinye kanye nezinga lokushisa lokushisa. Inani le-B le-NTC thermistor lihambisana ngokuqondile ne-coefficient yokushisa yomkhiqizo, okusho ukuthi, lapho inani le-B likhulu, i-coefficient yokushisa yalo 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; i-RT1, RT2: amanani okumelana kwe-thermistor emazingeni okushisa afanele u-T1, u-T2; u-T1, u-T2: isikali sokushisa esiphelele.
I-B value ye-NTC thermal resistor ivamise ukuba phakathi kuka-2000K-6000K, ngokuya ngendawo yokusebenza ehlukene ungakhetha i-B value ehlukene. Ngokuvamile, njengokulinganisa izinga lokushisa, ukulungisa izinga lokushisa kanye nokunciphisa ukuvuvukala, ungakhetha i-B value enkulu. Lokhu kungenxa yokuthi njengoba izinga lokushisa lishintsha, imikhiqizo enezinga le-B elikhulu ibonisa ushintsho olukhulu ku-resistor value, okusho ukuthi i-NTC thermal resistor B value inkulu, uma isetshenziswa ibonisa ukuphendula okukhulu, 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 be-resistor obudingekayo; uma ungazi uhlobo, kuzodingeka usebenzise izinga lokushisa, isimo sokusetshenziswa kanye ne-resistor value, i-B value, ukunemba kanye nobude be-resistor obudingekayo.
Umbuzo:I-NTC thermistor iyashesha kangakanani ukuphendula?
A：Isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyinto ebonisa ikhwalithi. Uma isikhala sikhulu, ukuphendula kuba kushesha. Isivinini sokuphendula se-sensor esihlukene sisheshisa kune-sensor efanayo efakwe ngaphakathi kwesikhwama sensimbi. Isikhathi esijwayelekile sokuphendula se-MF52 uchungechunge lwe-NTC thermal resistor sensor <15 imizuzwana.
Umbuzo:Yiluphi uhlobo lwesenzisi sokushisa esinikezwa yinkampani yakho? Yiziphi izinhlobo?
Impendulo:I-temperature sensor yenkampani yethu ingeyakhoI-NTC type temperature sensor, ngokwezimo ezahlukene zokusebenzisa kanye nezakhiwo, kukhona izinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwamapayipi aqondile, uhlobo lwe-screw, uhlobo lwe-flange, uhlobo lwebhola, uhlobo oluvaliwe lwe-epoxy resin, uhlobo lwe-lock sheet terminal, uhlobo lwe-ABS plastic shell, kanye nohlobo lwe-film. Ngaphezu kwalokho, inkampani yethu nayo inama-PT100/PT1000 temperature sensors, ama-DS18B20 temperature sensors, ama-thermocouples, kanye nama-infrared temperature sensors.
Umbuzo:Ingabe i-sensor yokushisa yenkampani yakho iyatholakala? Ingabe iyasekela ukwenza ngokwezifiso?
Impendulo:I-temperature sensor ingumkhiqizo othile, futhi izidingo zamakhasimende ahlukene ziyahlukahluka. Imikhiqizo esitokweni ingeyohlobo oluvaliwe lwe-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 lwe-sensor yokushisa okufanele isetshenziswe, ingabe kungenzeka ukuthi uncoma?
A：Impela, ngoba kunezinhlobo eziningi zokuxhumana, lapho ikhasimende lingacacisi, sincoma ikhasimende ngokusekelwe esimweni 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 ethandwa eminyakeni edlule, kufanele kube khona emikhiqizweni yethu. Akukhona kuphela amandla amasha,Imikhiqizo esetshenziswa ku-3D printing nakwezinye izinkalo sikhona, ibanzi kakhulu.

Umbuzo: Ngingayithola kanjani ithebula le-R-T le-NTC thermistor nezsenzisi lokushisa?
A：Yebo, umkhiqizo uzoba ne-R-T ithebula, futhi idatha ehlukene evela kubakhiqizi ehlukene iyatholakala. Uma kudingeka i-R-T ithebula yomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole izeluleko.
Umbuzo: Ingabe inkampani yakho ingasiza ekwakheni imikhiqizo nokudweba imidwebo?
A：Yebo, kungenzeka. Imidwebo yomkhiqizo idinga ukuhlinzeka ngemininingwane yezingxenye zomkhiqizo, kuhlanganise nezinto, usayizi kanye nezinye izidingo ezikhethekile, kanti futhi kudingeka ukuthola imvume ekhethekile.
