style="text-indent:25px">高精度角度傳感器（也稱高精度角度編碼器）采用采用磁電原理進(jìn)行測角，無觸點(diǎn)、長壽命，具有高可靠性、追蹤速度快、耐高低溫、防水、防塵及腐蝕性氣體、抗振動(dòng)等特點(diǎn)，具有高精度、高可靠性、追蹤速度快、耐高低溫、防水、防塵及腐蝕性氣體、抗振動(dòng)、抗強(qiáng)電磁干擾等特點(diǎn)。普遍應(yīng)用于要求精度高和可靠性高的各種惡劣環(huán)境中。高精度角位移傳感器是替代光電式編碼器和磁編碼器的理想產(chǎn)品。三大系列外形尺寸、測角分辨率30′～0.6″、精確度30′～5″、數(shù)據(jù)刷新速率＞5KHz。高精度角度編碼器脈沖丟失的原因是高精度角度編碼器安裝過程中出現(xiàn)敲擊，沖撞等機(jī)械損傷。絕對(duì)角度編碼器生產(chǎn)</p><p

style="text-indent:25px">高精度角度編碼器的優(yōu)點(diǎn)：體積小，精密，本身分辨度可以很高，無接觸無磨損;同一品種既可檢測角度位移，又可在機(jī)械轉(zhuǎn)換裝置幫助下檢測直線位移;多圈光電***編碼器可以檢測相當(dāng)長量程的直線位移(如25位多圈)。壽命長，安裝隨意，接口形式豐富，價(jià)格合理。成熟技術(shù)，多年前已在國內(nèi)外得到普遍應(yīng)用。缺點(diǎn)：精密但對(duì)戶外及惡劣環(huán)境下使用提出較高的保護(hù)要求；量測直線位移需依賴機(jī)械裝置轉(zhuǎn)換，需消除機(jī)械間隙帶來的誤差；檢測軌道運(yùn)行物體難以克服滑差。天津高清編碼器報(bào)價(jià)</p></p><br
