霍爾元件時使用注意事項1.霍爾是敏感器件，在使用過程以及存儲過程中應(yīng)注意采取靜電防護措施。2.適宜的電源電壓和負載電路及工作溫度是霍爾器件正常工作的先決條件，霍爾器件的供電電壓，負載電流及工作溫度不得超出規(guī)格書中多規(guī)定的范圍。3.所用工具，特別是焊接用的電烙鐵，必須嚴格接上地線，以保證電烙鐵不漏電，即電烙鐵的鐵皮是接地的，比較好選用低壓恒溫可調(diào)電烙鐵進行焊接。4.所有設(shè)備都應(yīng)嚴格接地，并用檢電筆逐個查明確無漏電，才能開始工作。5.要求印制板及霍爾器件管腳嚴格經(jīng)過清潔處理，使它與焊錫有良好的浸潤性。6.由于機械應(yīng)力會造成霍爾器件磁敏感度的漂移，在使用安裝中應(yīng)盡量減少施加到器件外殼和引線上的機械力，如管腳需要彎曲，請在距引線根部3mm以外操作。7.將導(dǎo)線平行焊接在霍爾器件的引腳上，焊接時不能掰動霍爾器件引腳。8.建議焊接溫度：電烙鐵焊接，建議溫度在350℃，**長5秒；波峰焊：建議比較高溫度260℃，**長3秒；紅外回流焊：建議比較高245℃，**長10秒。9.焊點不得有毛刺，以避免將熱縮管刺破而導(dǎo)致短路燒壞霍爾器件。10.熱縮管必須套在霍爾器件的引腳根部，保證器件充分絕緣，比較好在熱縮管及引線的下面再鋪一層絕緣紙。徐州線性霍爾元件哪家好質(zhì)量霍爾元件,中國**霍爾元件,選霍爾,找華芯!華芯霍爾元件,穩(wěn)定性強,一致性高,無抖動,高精度,抗應(yīng)力。</p><div

<p> 在用霍爾傳感器測量直流電動機的轉(zhuǎn)速時，將一個小磁鐵塊固定在電機的轉(zhuǎn)子上，將霍爾傳感器（開關(guān)型）靠近小磁鐵附近，當電機轉(zhuǎn)動以后，磁鐵會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低電平，當小磁鐵遠離傳感器時，傳感器輸出一個高電平。將這個脈沖送到單片機內(nèi)部定時器，計算出脈沖一個周期的時間，就可以算出電機的轉(zhuǎn)速。 </p><p> 霍爾元件的應(yīng)用我司供應(yīng)各種型號的霍爾元件。根據(jù)應(yīng)用的不同可以分為開關(guān)型霍爾元件和線性霍爾元件。開關(guān)型霍爾元件又分為雙極鎖存型霍爾元件、全極霍爾元件、全極微功耗霍爾元件，單極霍爾元件。具體選型如下：雙極霍爾元件：檢測電機的轉(zhuǎn)速與位置、流量計、風扇電機、微型電機、無刷電機如HX41F、HXS41H、HX6571、HX6572等全極霍爾元件：數(shù)碼產(chǎn)品、水表、電表、燃氣表、電池供電的產(chǎn)品、智能水表、開關(guān)、手持設(shè)備如HX6383、HX6382、HX6393、HX6344等單極霍爾元件：電機、計數(shù)、轉(zhuǎn)速、開關(guān)、調(diào)檔位、擋車桿、接近開關(guān)、無刷電機、轉(zhuǎn)速檢測、流量傳感、無接觸式定位如HX6286、HX3144、HX6287、HX6287等線性霍爾元件：電流傳感器、踏板、轉(zhuǎn)把、速度調(diào)節(jié)、壓力傳感、磁場檢測如HX6689、HX6649、HX6659、HX6639、HX6669等。霍爾元件哪家好？無錫華芯霍爾元件是專業(yè)的霍爾元件生產(chǎn)廠家，提供市面上的霍爾元件選型配型。</p><div

如何使用霍爾元件檢測磁場？使用霍爾器件檢測磁場的方法極為簡單，將霍爾器件作成各種形式的探頭，放在被測磁場中，因霍爾器件只對垂直于霍爾片的表面的磁感應(yīng)強度敏感，因而必須令磁力線和器件表面垂直，通電后即可由輸出電壓得到被測磁場的磁感應(yīng)強度。若不垂直，則應(yīng)求出其垂直分量來計算被測磁場的磁感應(yīng)強度值。而且，因霍爾元件的尺寸極小，可以進行多點檢測，由計算機進行數(shù)據(jù)處理，可以得到場的分布狀態(tài)，并可對狹縫，小孔中的磁場進行檢測。徐州線性霍爾元件哪家好</p><p
