在磁性傳感器中，利用霍爾效應(yīng)的傳感器稱為霍爾傳感器。霍爾傳感器包括幾個部分。首先，它包含一個霍爾元件，該霍爾元件輸出通過霍爾效應(yīng)產(chǎn)生的霍爾電壓（HV）。其次，它包含一個霍爾IC，該霍爾IC使霍爾輸出通過IC工藝變?yōu)楦?低數(shù)字輸出。第三，它包含一個線性霍爾IC，可放大并線性化霍爾輸出。 </p> <p> 霍爾元件 </p> <p> 特點(diǎn) </p> <p> 霍爾元件是一個簡單的傳感器，其端子連接在半導(dǎo)體上，因此根據(jù)后續(xù)階段的電路設(shè)計，它可以用于數(shù)字和模擬目的。輸出電壓可達(dá)幾十到幾百毫伏。 </p> <p> 輸出特性 </p> <p> 輸出電壓與垂直施加到傳感器的磁場強(qiáng)度成正比，并將根據(jù)磁場方向輸出正電壓和負(fù)電壓。沒有垂直磁場時的輸出電壓為0 V（* 1）。電流互感器的安裝必須牢固，互感器外殼的金屬外露部分應(yīng)可靠接地。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">第一階段是從霍爾效應(yīng)的發(fā)現(xiàn)到20世紀(jì)40年代前期。初，由于金屬材料中的電子濃度很大，而霍爾效應(yīng)十分微弱, 所以沒有引起人們的重視。這段時期也有人利用霍爾效應(yīng)制成磁場傳感器, 但實(shí)用價值不大,到了1910年有人用金屬鉍制成霍爾元件，作為磁場傳感器。但是，由于當(dāng)時未找到更合適的材料, 研究處于停頓狀態(tài)。第二階段是從20世紀(jì)40年代中期半導(dǎo)體技術(shù)出現(xiàn)之后，隨著半導(dǎo)體材料、制造工藝和技術(shù)的應(yīng)用，出現(xiàn)了各種半導(dǎo)體霍爾元件，特別是鍺的采用推動了霍爾元件的發(fā)展，相繼出現(xiàn)了采用分立霍爾元件制造的各種磁場傳感器、磁羅盤、磁頭、電流傳感器、非接觸開關(guān)、接近開關(guān)、位置、角度、速度、加速度傳感器、壓力變送器、無刷直流電機(jī)以及各種函數(shù)發(fā)生器、運(yùn)算器等, 應(yīng)用十分。穿心式電流互感器其本身結(jié)構(gòu)不設(shè)一次繞組。深圳電流互感器定制報價</p><p style="text-indent:25px">電流互感器的工作原理、等值電路與一般變壓器相同。深圳電流互感器定制報價</p><p
