霍爾開關(guān)怎么使用？霍爾器件是一種對(duì)磁場(chǎng)強(qiáng)度起反應(yīng)的小型器件，只要它附近的磁場(chǎng)有變化它就有反應(yīng)并輸出相應(yīng)的電壓或脈沖電壓（開關(guān)型霍爾器件）。 </p> <p> 在用霍爾傳感器測(cè)量直流電動(dòng)機(jī)的轉(zhuǎn)速時(shí)，將一個(gè)小磁鐵塊固定在電機(jī)的轉(zhuǎn)子上，將霍爾傳感器（開關(guān)型）靠近小磁鐵附近，當(dāng)電機(jī)轉(zhuǎn)動(dòng)以后，磁鐵會(huì)以一定的周期靠近傳感器一次，這樣霍爾傳感器將輸出一個(gè)低電平，當(dāng)小磁鐵遠(yuǎn)離傳感器時(shí)，傳感器輸出一個(gè)高電平。將這個(gè)脈沖送到單片機(jī)內(nèi)部定時(shí)器，計(jì)算出脈沖一個(gè)周期的時(shí)間，就可以算出電機(jī)的轉(zhuǎn)速。 </p><p> 線性霍爾電路由霍爾開關(guān)、差分放大器和射極跟隨器組成。其輸入是磁感應(yīng)強(qiáng)度，輸出是和輸入量成正比的電壓。這類電路有很高的靈敏度和優(yōu)良的線性度，適用于各種磁場(chǎng)檢測(cè)。 </p> <p> 線性霍爾開關(guān)的特點(diǎn)： </p> <p> 1、體積小、精確度高；2、靈敏度高、線性度好；3、溫度穩(wěn)定性好、可靠性高 </p> <p> 線性霍爾一些應(yīng)用領(lǐng)域： </p> <p> 1、電流傳感器；2、電源感應(yīng) 、磁（偏）傳感應(yīng)用、黑色金屬探測(cè)器、接近傳感器、液**置傳感器。 </p> <p> 線性霍爾電路注意事項(xiàng)；1 安裝時(shí)要盡量減少施加在電路外殼或引線上的機(jī)械應(yīng)力。；2 焊接溫度要低于260℃，時(shí)間小于5秒。；3若以N極從背面接近霍爾電路，輸出電壓減小，S極從背面接近，輸出增加；若從正面接近，輸出狀態(tài)與從背面接近正好相反。華芯是質(zhì)量的霍爾元件供應(yīng)廠家,長(zhǎng)期供應(yīng)霍爾元件產(chǎn)品,種類齊全,十六年專業(yè)品質(zhì),我們只做質(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(guò)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(guò)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。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!廣東HX6639霍爾開關(guān)價(jià)格</p><p
