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 ukusebenza kwezinga lokushisa elibi, futhi i-thermistor esetshenziselwa ukumela ukusebenza kwezinga lokushisa elibi ibizwa ngokuthiI-NTC thermistor (Negative Temperature Coefficient Thermal sensitivity resistor).
Izinhlobo ezivamile zihlanganisa: uhlobo oluvalwe nge-glass oluhlangene, uhlobo lwebhola olune-black head encane, uhlobo lwebhola olune-enamel wire, uhlobo lwebhola olune-plastic wire encane, uhlobo lwe-clip-on black head, uhlobo lwe-insulating film, diode,Uhlobo lwamandlakanye nama-resistors e-chip.
Q:Yimiphi imingcele yobuchwepheshe ye-NTC thermistor? Sicela unikeze izibonelo.
A:Ipharamitha eyinhloko yobuchwepheshe ihlanganisa: ukumelana okubizwa (5K/10K/50K/100K…), ukubekezelelana kwe-resistance (ukucacisa)(1%/3%/5%/10%), isici sokushisa sokumelana (B value) (3270/3380/3435/3470/3950/4000/4050/4500…), uhla lokushisa lokusebenza (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…), izinto eziyisisekelo, isikhathi sokusebenza…
Q:YiniYini i-B value ye-NTC thermistor?
A:I-B value iyisilinganiso sezinto ze-thermistor coefficient ye-thermal (index ye-thermal), eyi-unit ye-temperature ye-Kelvin (K). I-NTC thermistor chip enokuphikiswa okuthile yenziwa ngokushisa i-ceramic ye-semiconductor ezingeni lokushisa eliphezulu bese idlula uchungechunge lwezinqubo zokucubungula. Kukhona kuphela i-B value eyodwa yazo zonke izindlela zokupheka kanye nezinga lokushisa lokushisa. I-B value ye-NTC thermistor ihlobene ngokuqondile ne-thermal coefficient ye-resistance yomkhiqizo, okusho ukuthi, lapho i-B value inkulu, i-thermal coefficient ye-resistance yayo nayo iba nkulu.
Ifomula ye-B value ye-NTC thermistor yile: B=T1T2Ln(RT1/RT2)/(T2-T1) lapho i-B: i-B value ye-NTC thermistor, ehlinzekwa umkhiqizi; RT1, RT2: amanani okumelana kwe-thermistor ezingeni lokushisa T1, T2 ngokulandelana; T1, T2: isikali sokushisa esiphelele.
Inani le-B le-NTC thermistor ngokuvamile lingaphakathi kuka-2000K-6000K, futhi ungakhetha inani le-B elihlukile ngokuya ngohlu lokusebenza oluhlukile. Ngokuvamile, imikhiqizo esetshenziselwa ukulinganisa izinga lokushisa, ukukhokhelwa kwezinga lokushisa, kanye nokucindezela ukwanda kungasebenzisa inani elikhulu le-B. Ngoba lapho izinga lokushisa lishintsha, imikhiqizo enenani elikhulu le-B inokumelana okukhulu okushintshayo, okungukuthi, lapho inani le-NTC thermistor B likhulu, liyazwela kakhudlwana lapho lisebenza, futhi isikhathi sokuphendula siyashesha.
Q:Uku-odaYimiphi imininingwane edingekayo lapho u-oda i-NTC thermistor?
A:Uma kukhona uhlobo lwe-resistance oluqinisekisiwe, udinga ukuhlinzeka nge-resistance value,i-B value, ukucacisa, kanye nobude be-resistance obudingekayo; uma ungacacile ngohlobo, udinga ukusebenzisa izinga lokushisa, isimo sokusetshenziswa, kanye ne-resistance value, i-B value, ukucacisa, kanye nobude be-resistance obudingekayo.
Q:I-NTC thermistor iyashesha kangakanani ukusabela?
A:isikhathi sokuphendula sichazwa njengokufinyelela62% noma isikhathi esidingekayo sokushisa okusha, futhi kuyisici sekhwalithi. 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? Zinezinhlobo eziningaki?
A:Iningi lezinzwa zokushisa zenkampani yethu zingezakhoIzinzwa zokushisa ze-NTC, ngokuya ngezimo zokusebenzisa kanye nemiqulu ehlukene, kunezinhlobo ezilandelayo ongakhetha kuzo: uhlobo lwamapayipi aqondile, uhlobo lwezintambo, uhlobo lwe-flange, uhlobo lwebhola, uhlobo lokufakwa kwe-epoxy, uhlobo lwesixhumi sesikhiye, uhlobo lwekhava yepulasitiki ye-ABS, kanye nohlobo lwe-film. 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 ngokwezifiso?
A:Ama-temperature sensors angumkhiqizo othile, futhi izidingo zamakhasimende ziyahlukahluka. Imikhiqizo esitokweni ikakhulu ingeyohlobo oluvalwe nge-epoxy resin, kanti ezinye izinhlobo azivamile.
Imikhiqizo yethu isekela ukwenza 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 kungenjalo kucacile ukuthi hlobo luni lwe-temperature sensor oludingekayo, ingabe kungenzeka ukuncoma?
A:Impela, ngoba ngithintana nezinhlobo eziningi, lapho ikhasimende lingacacile, sizoncoma ikhasimende ngokuya ngesimo sokusetshenziswa kanye nezidingo ezithile ukuze ikhasimende lithole umkhiqizo owanele. Ngaphezu kwalokho, singakwazi futhi ukubambisana nokulungisa umklamo womkhiqizo ngesikhathi ngokuya ngezidingo zamakhasimende, ukuze senze umkhiqizo owanele owudingwa ikhasimende.
Q:Ingabe ihilela imikhiqizo yezimboni ezintsha zamandla?
A:Amandla amasha ayinto ethandwayo eminyakeni yamuva nje, futhi kufanele ibe khona emikhiqizweni yethu. Akuyona nje amandla amasha, kodwaSiphinde sibe nemikhiqizo esetshenziswa ku-3D printing nezinye izindawo, futhi siyahlukahlukene.

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. C
