線性霍爾效應(yīng)器件對(duì)電流檢測(cè)來說是理想的，可以精確的測(cè)量由幾毫安到幾千安培的電流值。電流通過導(dǎo)體將產(chǎn)生一個(gè)大約每。因?yàn)橐粋€(gè)霍爾器件的測(cè)量范圍是有限的，所以，需要配置檢測(cè)電路使被測(cè)量的電流強(qiáng)度范圍是在器件允許的范圍內(nèi)?；魻栭_關(guān)工作原理霍爾開關(guān)就屬于有源磁電轉(zhuǎn)換器件，它是在霍爾效應(yīng)原理的基礎(chǔ)上，利用集成封裝和組裝工藝制作而成，它可方便的把磁輸入信號(hào)（磁感應(yīng)信號(hào)）轉(zhuǎn)換成實(shí)際應(yīng)用中的電信號(hào)?；魻栭_關(guān)的輸入端是以磁感應(yīng)強(qiáng)度B來表征的，當(dāng)B值達(dá)到一定的程度時(shí)，霍爾開關(guān)內(nèi)部的觸發(fā)器翻轉(zhuǎn)，霍爾開關(guān)的輸出電平狀態(tài)也隨之翻轉(zhuǎn)。輸出端一般采用晶體管輸出。所以霍爾開關(guān)的效果與我們?nèi)粘Ｉ罱佑|的開關(guān)效果是一致的。 </p><p> 如何判斷單極開關(guān)型霍爾開關(guān)是否有損壞？ </p> <p> 比如說，單極開關(guān)霍爾開關(guān)為5V接通，輸出端子的輸出電阻為串聯(lián)。當(dāng)磁體遠(yuǎn)離開關(guān)霍爾開關(guān)時(shí)，開關(guān)霍爾開關(guān)的輸出電壓為高電平(5V)。當(dāng)磁體接近(通常為S極)單極霍爾開關(guān)元件時(shí)，開關(guān)霍爾開關(guān)的輸出電壓較低(約0.2V)，說明開關(guān)開型霍爾開關(guān)性能良好。如果霍爾開關(guān)的輸出電平保持不變，就無法識(shí)別磁鐵接近或離開霍爾開關(guān)，則霍爾開關(guān)損壞。單極霍爾開關(guān)起到的就是開關(guān)功能，通過感應(yīng)磁場(chǎng)靠近或者原理來輸出低電壓或者高電壓，如果電壓不變，這個(gè)霍爾就已經(jīng)被損壞了。霍爾元件廠家哪家好?十六年專業(yè)做霍爾,霍爾傳感器華芯晟霍爾元件廠家十六年專業(yè)品質(zhì),只做質(zhì)量霍爾!</p><div

霍爾元件應(yīng)用霍爾效應(yīng)的半導(dǎo)體。所謂霍爾效應(yīng)，是指磁場(chǎng)作用于載流金屬導(dǎo)體、半導(dǎo)體中的載流子時(shí)，產(chǎn)生橫向電位差的物理現(xiàn)象。金屬的霍爾效應(yīng)是1879年被美國(guó)物理學(xué)家霍爾發(fā)現(xiàn)的。當(dāng)電流通過金屬箔片時(shí)，若在垂直于電流的方向施加磁場(chǎng)，則金屬箔片兩側(cè)面會(huì)出現(xiàn)橫向電位差。半導(dǎo)體中的霍爾效應(yīng)比金屬箔片中更為明顯，而鐵磁金屬在居里溫度以下將呈極強(qiáng)的霍爾效應(yīng)。利用霍爾效應(yīng)可以設(shè)計(jì)制成多種傳感器?；魻栯娢徊頤H的基本關(guān)系為：式中 RH――霍爾系數(shù)；n――單位體積內(nèi)載流子或自由電子的個(gè)數(shù)；q――電子電量；I――通過的電流；B――垂直于I的磁感應(yīng)強(qiáng)度；d――導(dǎo)體的厚度。對(duì)于半導(dǎo)體和鐵磁金屬，霍爾系數(shù)表達(dá)式和式（2）不同。由于通電導(dǎo)線周圍存在磁場(chǎng)，其大小和導(dǎo)線中的電流成正比，故可以利用霍爾元件測(cè)量出磁場(chǎng)，就可確定導(dǎo)線電流的大小。利用這一原理可以設(shè)計(jì)制成霍爾電流傳感器。若把霍爾元件置于電場(chǎng)強(qiáng)度為E、磁場(chǎng)強(qiáng)度為H的電磁場(chǎng)中，則在該元件中將產(chǎn)生電流I，元件上同時(shí)產(chǎn)生的霍爾電位差和電場(chǎng)強(qiáng)度E成正比，如果再測(cè)出該電磁場(chǎng)的磁場(chǎng)強(qiáng)度，則電磁場(chǎng)的功率密度瞬時(shí)值P可由確定。天津HX254霍爾開關(guān)</p><p
