一、概述：<\/span><\/p>\r

HG71<\/span><\/span>磁電轉(zhuǎn)速傳感器，能將轉(zhuǎn)角位移轉(zhuǎn)換成電信號(hào)供計(jì)數(shù)器計(jì)數(shù)，只要非接觸就能測(cè)量各種導(dǎo)磁材料如：如齒輪、葉輪、帶孔（或槽<\/span>、<\/span>螺釘）圓盤(pán)的轉(zhuǎn)速及線速度。<\/span><\/p>\r

傳感器具有：體積小<\/span>、<\/span>結(jié)實(shí)可靠<\/span>、<\/span>壽命長(zhǎng)<\/span>、<\/span>不需電源和潤(rùn)滑油等優(yōu)點(diǎn)，與一般二次儀表均可配用。<\/span><\/p>\r

二、技術(shù)參數(shù)<\/span><\/p>\r

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

2、     <\/span><\/span><\/span><\/span>輸出信號(hào)幅值<\/span>：<\/span><\/p>\r

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

　　　　　　　　　　　　　　<\/span>             <\/span>  <\/span><\/span><\/span>被測(cè)齒輪模數(shù)　<\/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(hào)幅值大小，與轉(zhuǎn)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(cè)量范圍：<\/span>20<\/span>～10000Hz<\/span><\/span><\/p>\r

4、  <\/span><\/span><\/span><\/span>使用時(shí)間：連續(xù)使用<\/span><\/p>\r

5、     <\/span><\/span><\/span><\/span>工作環(huán)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(zhǎng)80mm<\/span><\/span><\/p>\r

 <\/span>8<\/span>、重量：約120g<\/span>（不計(jì)輸出導(dǎo)線）<\/span><\/p>\r

三、外形圖：<\/span><\/p>\r

 <\/p>\r

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

四、使用注意事項(xiàng)<\/span><\/p>\r

　　�。�、安裝時(shí)傳感器外殼M16<\/span>×1<\/span>螺紋不得損傷，六角螺母旋轉(zhuǎn)應(yīng)自如，六角螺母并緊后，不得有松動(dòng)現(xiàn)象。<\/span><\/p>\r

　　�。病惭b時(shí)應(yīng)以被測(cè)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(hào)幅值。<\/span><\/p>\r
