霍爾開關(guān)對應(yīng)的工作磁體的設(shè)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(yīng)強度。在空氣隙中，磁感應(yīng)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(guān)器件的可靠工作，在應(yīng)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(yīng)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(dāng)位置，用它去檢測工作磁場，再從檢測結(jié)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(cè)移；(c)旋轉(zhuǎn)；(d)遮斷。深圳霍爾開關(guān)價格霍爾哪家好,買霍爾元件還是選華芯晟!華芯晟提供各種類型的霍爾元件

行車記錄儀是一種記錄車輛在行駛過程中的圖像和聲音的儀器。行車記錄儀安裝好后，可以記錄車輛行駛?cè)^程的視頻圖像和聲音，為交通意外提供充分的證據(jù)。 </p> <p> 行車記錄儀霍爾傳感器主要起行車記錄儀的速度檢測功能。行車記錄儀霍爾傳感器一般采用全極霍爾傳感器。交通記錄儀霍爾傳感器的應(yīng)用范圍很廣，不同類型的溫度會有所不同。行車記錄儀的霍爾傳感器也會有所不同，類型選擇也比較普遍。一般使用全極微功耗的霍爾元件，如如HX6383，HX6382,HX6363,HX6373等 </p><p>
