霍爾元件對(duì)應(yīng)的工作磁體的設(shè)置用磁場(chǎng)作為被傳感物體的運(yùn)動(dòng)和位置信息載體時(shí)，一般采用長(zhǎng)久磁鋼來(lái)產(chǎn)生工作磁場(chǎng)。例如，用一個(gè)5×4×（mm3）的釹鐵硼Ⅱ號(hào)磁鋼，就可在它的磁極表面上得到約2300高斯的磁感應(yīng)強(qiáng)度。在空氣隙中，磁感應(yīng)強(qiáng)度會(huì)隨距離增加而迅速下降。為保證霍爾器件，尤其是霍爾開(kāi)關(guān)器件的可靠工作，在應(yīng)用中要考慮有效工作氣隙的長(zhǎng)度。在計(jì)算總有效工作氣隙時(shí)，應(yīng)從霍爾片表面算起。在封裝好的霍爾電路中，霍爾片的深度在產(chǎn)品手冊(cè)中會(huì)給出。因?yàn)榛魻柶骷枰ぷ麟娫?，在作運(yùn)動(dòng)或位置傳感時(shí)，一般令磁體隨被檢測(cè)物體運(yùn)動(dòng)，將霍爾器件固定在工作系統(tǒng)的適當(dāng)位置，用它去檢測(cè)工作磁場(chǎng)，再?gòu)臋z測(cè)結(jié)果中提取被檢信息。工作磁體和霍爾器件間的運(yùn)動(dòng)方式有：(a)對(duì)移；(b)側(cè)移；(c)旋轉(zhuǎn)；(d)遮斷。

2.開(kāi)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。 </p> <p> 3.單獨(dú)檢查下磁鐵，有些磁鐵存在時(shí)間過(guò)長(zhǎng)使磁鐵消磁，導(dǎo)致霍爾感應(yīng)不到，無(wú)法正常工作。（注：霍爾與磁鐵之間有阻隔也會(huì)減弱磁場(chǎng)） </p> <p> 4.是否超出了霍爾本身的溫度范圍，溫度過(guò)高會(huì)導(dǎo)致霍爾損壞，也會(huì)導(dǎo)致磁鐵消磁。 </p> <p> 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。華芯十七年專業(yè)做霍爾，提供多種類型的霍爾元件，歡迎咨詢選購(gòu)。河源華芯霍爾元件價(jià)格</p><p
