style="text-indent:25px">霍爾效應(yīng)傳感器也稱霍爾傳感器，是根據(jù)霍爾效應(yīng)制作的一種磁場傳感器，普遍地應(yīng)用于工業(yè)自動化技術(shù)、檢測技術(shù)及信息處理等方面。由于霍爾元件產(chǎn)生的電勢差很小，故通常將霍爾元件與放大器電路、溫度補(bǔ)償電路及穩(wěn)壓電源電路等集成在一個(gè)芯片上，稱之為霍爾傳感器。 1、原邊導(dǎo)線應(yīng)放置于傳感器內(nèi)孔中心，盡可能不要放偏； 2、原邊導(dǎo)線盡可能完全放滿傳感器內(nèi)孔，不要留有空隙； 3、需要測量的電流應(yīng)接近于傳感器的標(biāo)準(zhǔn)額定值IPN，不要相差太大。如條件所限，手頭*有一個(gè)額定值很高的傳感器，而欲測量的電流值又低于額定值很多，為了提高測量精度，可以把原邊導(dǎo)線多繞幾圈，使之接近額定值。例如當(dāng)用額定值100A的傳感器去測量10A的電流時(shí)，為提高精度可將原邊導(dǎo)線在傳感器的內(nèi)孔中心繞十圈(一般情況，NP=1；在內(nèi)孔中繞一圈，NP=2；……；繞九圈，NP=10，則NP×10A=100A與傳感器的額定值相等，從而可提高精度)； 4、當(dāng)欲測量的電流值為IPN/10的時(shí)，在25℃仍然可以有較高的精度。在霍爾電流傳感器中，霍爾元器件是關(guān)鍵元器件，其性能影響著產(chǎn)品的性能。深圳霍爾傳感器一般多少錢</p><p style="text-indent:25px">霍爾電流傳感器是按照霍爾效應(yīng)原理制成。廣州霍爾傳感器廠家哪家好</p><p
