一、概述：<\/span><\/p>\r

HG71<\/span><\/span>磁電轉速傳感器，能將轉角位移轉換成電信號供計數器計數，只要非接觸就能測量各種導磁材料如：如齒輪、葉輪、帶孔（或槽<\/span>、<\/span>螺釘）圓盤的轉速及線速度。<\/span><\/p>\r

傳感器具有：體積小<\/span>、<\/span>結實可靠<\/span>、<\/span>壽命長<\/span>、<\/span>不需電源和潤滑油等優點，與一般二次儀表均可配用。<\/span><\/p>\r

二、技術參數<\/span><\/p>\r

1、     <\/span><\/span><\/span><\/span>輸出波形：近似正弦波（<\/span>≥<\/span>50r/min<\/span><\/span>時）<\/span><\/p>\r

2、     <\/span><\/span><\/span><\/span>輸出信號幅值<\/span>：<\/span><\/p>\r

        <\/span>50r/min<\/span><\/span>時<\/span>≥300<\/span>ｍｖ 傳感器鐵芯和被測齒輪齒頂間隙　δ＝0.5<\/span>～1.2mm<\/span><\/span><\/p>\r

　　　　　　　　　　　　　　<\/span>             <\/span>  <\/span><\/span><\/span>被測齒輪模數　<\/span>m = 2<\/span><\/span><\/p>\r

                                                   <\/span><\/span><\/span>齒輪<\/span>  <\/span>Z = 60<\/span><\/span><\/p>\r

                          <\/span><\/span><\/span>　　　　　　　　<\/span>       <\/span><\/span><\/span>　材料<\/span>  <\/span><\/span><\/span>電工鋼<\/span><\/p>\r

　　　　信號幅值大小，與轉速成正比，與鐵芯和齒頂間隙的大小成反比。<\/span><\/p>\r

3、     <\/span><\/span><\/span><\/span>測量范圍：<\/span>20<\/span>～10000Hz<\/span><\/span><\/p>\r

4、  <\/span><\/span><\/span><\/span>使用時間：連續使用<\/span><\/p>\r

5、     <\/span><\/span><\/span><\/span>工作環境：溫度 -20<\/span>～+180<\/span>℃   <\/span><\/span><\/span><\/p>\r

6、<\/span><\/span>輸出形式：X12K4P<\/span>四芯插頭<\/span><\/p>\r

7<\/span>、外形尺寸：外徑M16<\/span>×1<\/span>　; M18<\/span>×1.5<\/span>總長80mm<\/span><\/span><\/p>\r

 <\/span>8<\/span>、重量：約120g<\/span>（不計輸出導線）<\/span><\/p>\r

三、外形圖：<\/span><\/p>\r

插頭端子1<\/span>、4<\/span>接信號輸出線<\/span><\/p>\r

四、使用注意事項<\/span><\/p>\r

　　�。薄惭b時傳感器外殼M16<\/span>×1<\/span>螺紋不得損傷，六角螺母旋轉應自如，六角螺母并緊后，不得有松動現象。<\/span><\/p>\r

　　�。病惭b時應以被測齒輪不與傳感器接觸為宜。并希望能盡量減少間隙δ以提高輸出信號幅值。<\/span><\/p>\r
