style="text-indent:25px">兩線制拉線位移傳感器的特點(diǎn)：1、兩線制的拉線位移傳感器，它的兩根線分別是電源線和信號(hào)線，只有兩根線我們只要根據(jù)接線圖上面的標(biāo)注找到電源線接到24V上，信號(hào)線接到信號(hào)上就可以，接線簡單，安裝方便。2.二線制電流信號(hào)拉線位移傳感器接線簡單易懂使用方便，體積小適合小空間安裝。兩根線及傳輸電源又傳輸信號(hào)，也就是傳感器輸出的負(fù)載和電源是串聯(lián)在一起的，電源是從外部引入的，和負(fù)載串聯(lián)在一起來驅(qū)動(dòng)負(fù)載。3、兩線制電流信號(hào)拉線位移傳感器量程范圍可以做大量程的，也可以做小量程的，量程范圍比較大0-10000mm都是可以做的。如需要特殊定制。請(qǐng)?zhí)崆昂图夹g(shù)人員溝通。</p><p

style="text-indent:25px">常見拉線編碼器本身故障和維修：（1）編碼器本身故障:是指編碼器本身元器件出現(xiàn)故障，導(dǎo)致其不能產(chǎn)生和輸出正確的波形。這種情況下需更換編碼器或維修其內(nèi)部器件。（2）編碼器+5V電源下降:是指+5V電源過低，通常不能低于4.75V，造成過低的原因是供電電源故障或電源傳送電纜阻值偏大而引起損耗，這時(shí)需檢修電源或更換電纜。（3）編碼器安裝松動(dòng):這種故障會(huì)影響位置控制精度，造成停止和移動(dòng)中位置偏差量超差，甚至剛一開機(jī)即產(chǎn)生伺服系統(tǒng)過載報(bào)警，請(qǐng)?zhí)貏e注意。（4）***式編碼器電池電壓下降:這種故障通常有含義明確的報(bào)警，這時(shí)需更換電池，如果參考點(diǎn)位置記憶丟失，還須執(zhí)行重回參考點(diǎn)操作。（5）編碼器連接電纜故障:這種故障出現(xiàn)的幾率比較高，維修中經(jīng)常遇到，應(yīng)是優(yōu)先考慮的因素。通常為編碼器電纜斷路、短路或接觸不良，這時(shí)需更換電纜或接頭。還應(yīng)特別注意是否是由于電纜固定不緊，造成松動(dòng)引起開焊或斷路，這時(shí)需卡緊電纜。（6）編碼器電纜屏蔽線未接或脫落:這會(huì)引入干擾信號(hào)，使波形不穩(wěn)定，影響通信的準(zhǔn)確性，必須保證屏蔽線可靠的焊接及接地。（7）光柵污染這會(huì)使信號(hào)輸出幅度下降，必須用脫脂棉沾無水酒精輕輕擦除油污。RS485拉線位移編碼器供貨價(jià)格</p></p><br
