霍爾開關對應的工作磁體的設置用磁場作為被傳感物體的運動和位置信息載體時，一般采用長久磁鋼來產(chǎn)生工作磁場。例如，用一個5×4×（mm3）的釹鐵硼Ⅱ號磁鋼，就可在它的磁極表面上得到約2300高斯的磁感應強度。在空氣隙中，磁感應強度會隨距離增加而迅速下降。為保證霍爾器件，尤其是霍爾開關器件的可靠工作，廣東全極微功耗霍爾開關，在應用中要考慮有效工作氣隙的長度。在計算總有效工作氣隙時，應從霍爾片表面算起。在封裝好的霍爾電路中，霍爾片的深度在產(chǎn)品手冊中會給出。因為霍爾器件需要工作電源，在作運動或位置傳感時，一般令磁體隨被檢測物體運動，將霍爾器件固定在工作系統(tǒng)的適當位置，用它去檢測工作磁場，再從檢測結果中提取被檢信息。工作磁體和霍爾器件間的運動方式有：(a)對移；(b)側移；(c)旋轉(zhuǎn)；(d)遮斷。霍爾元件選型，廣東全極微功耗霍爾開關,廠家直銷華芯霍爾元件，廣東全極微功耗霍爾開關,十六年專業(yè)做霍爾,無損耗耐用霍爾元件華芯幫您一站搞定,好評如潮!廣東全極微功耗霍爾開關</p><div

煙霧報警器，又稱煙霧傳感器、火災煙霧報警器、煙霧傳感器等。總線由總線供電，可連接到多個，與火警控制器連接，通信構成報警系統(tǒng)，報警現(xiàn)場無聲音，主機有聲光提示，這種煙霧報警裝置一般稱為煙霧探測器。 </p> <p> 在報警器內(nèi)部有應用到霍爾傳感器，在報警器中的霍爾傳感器起到了檢測自身電路的作用，當火災發(fā)生時煙霧報警器霍爾傳感器測量到市內(nèi)溫度達到一定點時，煙霧報警器就會亮燈并且開始運作，一般可以用磁鐵來靠近煙霧報警器來進行檢測，如果指示燈正常亮起這煙霧警報器一切正常，若沒亮起就必須要跟換新的報警器了。在煙霧報警器中常常會使用到全極霍爾傳感器。珠海單極霍爾開關全極霍爾元件哪家好?華芯全極霍爾元件品質(zhì)保障!華芯霍爾元件功耗低,一致性好,靈敏度高,**提供配型服務。</p><div

霍爾的感應距離也和磁場的強度有直接的關系，一般霍爾的感應距離是在1CM左右。一般來說，要先選霍爾，選好霍爾之后再去配套磁鐵，這樣磁鐵和霍爾的配套性更強。要是需要感應的距離比較遠，那么就需要加大磁場，或選擇高靈敏度的霍爾開關。感應距離的遠近是需要磁場和霍爾共同搭配來使用的，也或者您的磁場特別強，可能靈敏度稍微低一些的霍爾開關也是可以感應到的，當然還是需要您在實際的電路中去測試的。 </p><p
