NTC&温度传感器 Q&A
Q：什么是NTC热敏电阻？Yiziphi izinhlobo ezikhona?
Impendulo:Isici sokumelana esehla njengoba izinga lokushisa likhuphuka sibizwa ngokuthi isici sokushisa okungekuhle, i-thermistor esetshenziselwa ukukhombisa isici sokushisa okungekuhle ibizwa ngokuthiNTC热敏电阻(Negative Temperature Coefficient Thermal sensitivity resistor)。
常见的类型有：单端玻封型、珠型小黑头、珠型漆包线、珠型小皮线、卡点式小黑头、绝缘薄膜型、二极管、功率型以及贴片电阻。
Umbuzo:NTC热敏电阻的技术参数有哪些？请举例说明。
A：Amapharamitha ayinhloko ezobuchwepheshe ahlanganisa: inani elibekiwe le-resistance (5K/10K/50K/100K…）、阻值容差（精度）(1%/3%/5%/10%), i-coefficient yokushisa kwe-resistance (inani le-B) (3270/3380/3435/3470/3950/4000/4050/4500…), ububanzi bokushisa okusebenzayo (℃) (-30℃-105℃/-30℃-125℃/-40℃-250℃…)、材料常数、时间常数…
Umbuzo:什么是NTC热敏电阻的B值？
A:Inani le-B liyisici esingaguquki sezinto zokushisa kwe-thermistor (inkomba yokushisa), futhi iyunithi yalo i-Kelvin (K). I-semiconductor ceramic ngemva kokushiswa ngezinga lokushisa eliphezulu idlula ochungechungeni lwezinqubo zokucubungula yakhe i-NTC thermistor chip ene-resistance ethile, futhi inani le-B lihlala linye kuphela kunhlanganisela ngayinye kanye nezinga lokushisa lokushisa. Inani le-B le-NTC thermistor lihambisana kahle ne-coefficient yokushisa kwe-resistance yomkhiqizo, okusho ukuthi uma inani le-B likhulu, i-coefficient yokushisa kwe-resistance nayo iyakhula.
NTC热敏电阻B值公式为:B=T1T2Ln(RT1/RT2)/(T2-T1) 其中的B:NTC热敏电阻的B值，由厂家提供; RT1、RT2:热敏电阻在温度分别为T1、T2时的电阻值; T1、T2:绝对温标。
Inani le-B le-NTC thermistor ngokuvamile liphakathi kuka-2000K-6000K, futhi kungakhethwa amanani ahlukene e-B ngokuya ngezindawo ezahlukene zokusetshenziswa. Ngokuvamile, imikhiqizo esetshenziselwa ukulinganisa izinga lokushisa, ukunxephezela izinga lokushisa, kanye nokuvimbela i-surge ingakhetha inani elikhulu le-B. Ngoba njengoba izinga lokushisa lishintsha, umkhiqizo onenani elikhulu le-B ushintsha kakhulu kunenani elincane, okusho ukuthi uma inani le-B le-NTC thermistor likhulu, lisebenza ngokuzwela kakhulu futhi isikhathi sokuphendula siyashesha.
Q：订购Yiluphi ulwazi okudingeka luhlinzekwe uma kusetshenziswa i-NTC thermistor?
Impendulo:如果有已经确定的电阻类型，需要告知阻值、Inani le-B, ukunemba kanye nobude besistimu edingekayo; uma ungazi uhlobo, kudingeka izinga lokushisa, indawo yokusetshenziswa kanye nenani lokumelana, inani le-B, ukunemba kanye nobude besistimu edingekayo.
Q：NTC热敏电阻的反应速度有多快?
A：响应时间定义为达到Isikhathi esidingekayo ku-62% noma izinga lokushisa elisha, futhi kuwumsebenzi wekhwalithi. Uma inzwa incane, isabela ngokushesha. Ijubane lokuphendula lezinzwa ezihlukene lishesha kunezwa efanayo epakishwe ngaphakathi kwekhabethe lensimbi. Isikhathi sokuphendula esijwayelekile sezinzwa ze-MF52 series NTC thermistor singaphansi kwemizuzwana engu-15.
Q：贵司温度传感器是什么类型的温度传感器？有哪些类型呢？
A：Ama-sensor okushisa ethu amaningi angaphansi kwe-Inzwa yokushisa yohlobo lwe-NTC, kuye ngomkhakha wokusetshenziswa kanye nesakhiwo, kukhona uhlobo lwepayipi eliqondile, uhlobo lwentambo, uhlobo lwe-flange, uhlobo lwekhanda lesibhamu, uhlobo lokufakwa kwe-epoxy resin, uhlobo lwethemini lokukhiya, uhlobo lwe-ABS plastic casing kanye nohlobo lwefilimu ongakhetha kuzo. Ngaphezu kwalokho, inkampani yethu inezinzwa zokushisa ze-PT100/PT1000, izinzwa zokushisa ze-DS18B20, ama-thermocouple kanye nezinzwa zokushisa ze-infrared.
Umbuzo:贵司温度传感器有现货吗？是否支持定制呢？
A：温度传感器属于特定产品，不同的客户需求是存在差别的，现货产品多是环氧树脂密封型的，其他类型较少。
Imikhiqizo yethu isekela ukwenziwa ngokwezifiso, ama-thermistor okufanele asetshenziswe angakhethwa, futhi izingxenye ezingenziwa ngokwezifiso zihlanganisa: ubude, usayizi, nokuma kwezingxenye zensimbi, uhlobo, isici, nobude bentambo, kanye nokukhetha izinhlobo ezahlukene zokuxhuma.
Q：在不明确需要使用的温度传感器是什么类型时，是否可以推荐？
A:Lokhu kuyiqiniso, ngoba izinhlobo zokuxhumana ziningi, uma iklayenti lingacacisi, sizoncoma umkhiqizo ngokuya ngesimo sokusetshenziswa kweklayenti kanye nezidingo ezithile, ukuze iklayenti lithole umkhiqizo owanelisayo. Ngaphezu kwalokho, singakwazi futhi ukulungisa ukwakheka komkhiqizo ngokushesha ngokuhambisana nezidingo zeklayenti, futhi senze umkhiqizo owenelisa iklayenti.
Umbuzo:Ingabe kuhilela imikhiqizo yamandla amasha?
Impendulo:Amandla amasha abe yinto eshisayo eminyakeni yamuva, kufanele abe khona emikhiqizweni yethu. Hhayi nje amandla amasha,3D打印及其他领域使用的产品我们也有涉及，比较广泛的。

Q：NTC热敏电阻和温度传感器的R-T表如何获取呢？
Impendulo: Yebo, umkhiqizo uzoba netafula le-R-T elihambisana nawo, futhi idatha yabakhiqizi abahlukene iyahluka ngokwayo. Uma udinga itafula le-R-T lomkhiqizo, ungaxhumana nabasebenzi bethu ukuze uthole usizo.
Q：贵司是否可以帮忙设计产品、绘制图纸？
Impendulo: Yebo, kungenzeka. Ukudweba imidwebo yomkhiqizo kudinga ukunikezwa kwedatha yezingxenye ezahlukene zomkhiqizo, okuhlanganisa into, usayizi, nezinye izidingo ezikhethekile, futhi kudinga nemvume ekhethekile.
