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。我公司擁有世界前列霍爾研發(fā)能力，霍爾產(chǎn)品設(shè)計(jì)能力，與多家**科學(xué)研究院建立合作關(guān)系。江蘇HX492-A霍爾開關(guān)</p><p
