煙霧報(bào)警器，又稱煙霧傳感器、火災(zāi)煙霧報(bào)警器、煙霧傳感器等?？偩€由總線供電，可連接到多個(gè)，與火警控制器連接，通信構(gòu)成報(bào)警系統(tǒng)，報(bào)警現(xiàn)場(chǎng)無聲音，主機(jī)有聲光提示，這種煙霧報(bào)警裝置一般稱為煙霧探測(cè)器。 </p> <p> 在報(bào)警器內(nèi)部有應(yīng)用到霍爾傳感器，在報(bào)警器中的霍爾傳感器起到了檢測(cè)自身電路的作用，徐州鎖存型霍爾開關(guān)報(bào)價(jià)，當(dāng)火災(zāi)發(fā)生時(shí)煙霧報(bào)警器霍爾傳感器測(cè)量到市內(nèi)溫度達(dá)到一定點(diǎn)時(shí)，徐州鎖存型霍爾開關(guān)報(bào)價(jià)，徐州鎖存型霍爾開關(guān)報(bào)價(jià)，煙霧報(bào)警器就會(huì)亮燈并且開始運(yùn)作，一般可以用磁鐵來靠近煙霧報(bào)警器來進(jìn)行檢測(cè)，如果指示燈正常亮起這煙霧警報(bào)器一切正常，若沒亮起就必須要跟換新的報(bào)警器了。在煙霧報(bào)警器中常常會(huì)使用到全極霍爾傳感器。

電風(fēng)扇的主要部件是：雙線圈直流馬達(dá)電機(jī)其工作原理是帶電線圈在磁場(chǎng)作用下旋轉(zhuǎn)。能量轉(zhuǎn)換的形式是：電能主要轉(zhuǎn)化為機(jī)械能，同時(shí)由于線圈具有電阻，部分電能不可避免地轉(zhuǎn)化為熱能。 </p> <p> 風(fēng)扇中的霍爾開關(guān)主要用于雙線圈直流電機(jī)驅(qū)動(dòng)。風(fēng)扇中的霍爾開關(guān)也可用于CPU冷卻風(fēng)扇和直流冷卻風(fēng)扇。該風(fēng)扇霍爾開關(guān)工作電壓低，聲音很低，并且風(fēng)扇霍爾開關(guān)的穩(wěn)定性非常穩(wěn)定，與其他傳感器兼容。一般使用鎖存型霍爾元件，如HX41F-H,HXS41H,HX6571,HX6572,HX6573,HX6574等

造成霍爾開關(guān)失效的常見原因有哪些？我們?cè)谑褂没魻栭_關(guān)的過程中經(jīng)常會(huì)遇到霍爾工作了一段時(shí)間之后就停止工作的情況，這時(shí)，霍爾芯片可能是被損壞了，那是什么原因?qū)е碌哪?？可以從以下幾個(gè)方面來入手分析檢測(cè)：1.首先檢查外部電路，是否有虛焊漏焊的情況造成短路、斷路的現(xiàn)象。2.開關(guān)類的霍爾一般都需要外接一個(gè)上拉電阻才可以正常工作，檢查下電阻是否正常。3.單獨(dú)檢查下磁鐵，有些磁鐵存在時(shí)間過長(zhǎng)使磁鐵消磁，導(dǎo)致霍爾感應(yīng)不到，無法正常工作。（注：霍爾與磁鐵之間有阻隔也會(huì)減弱磁場(chǎng)）4.是否超出了霍爾本身的溫度范圍，溫度過高會(huì)導(dǎo)致霍爾損壞，也會(huì)導(dǎo)致磁鐵消磁。5.檢查電壓、電流是否穩(wěn)定，是否在霍爾參數(shù)規(guī)定范圍內(nèi)，偏上限或下限會(huì)造成霍爾不穩(wěn)定，超出參數(shù)范圍會(huì)導(dǎo)致霍爾被瞬間擊穿造成損壞。
