style="text-indent:25px">編碼器是把角位移或直線位移轉(zhuǎn)換成電信號的一種裝置。前者成為碼盤，后者稱碼尺，按照讀出方式編碼器可以分為接觸式和非接觸式兩種。接觸式采用電刷輸出，一電刷接觸導電區(qū)或絕緣區(qū)來表示代碼的狀態(tài)是"1"還是"0"；非接觸式的接受敏感元件是光敏元件或磁敏元件，采用光敏元件時以透光區(qū)和不透光區(qū)來表示代碼的狀態(tài)是"1"還是"0"。增量式編碼器是將位移轉(zhuǎn)換成周期性的電信號，再把這個電信號轉(zhuǎn)變成計數(shù)脈沖，用脈沖的個數(shù)表示位移的大小。編碼器的每一個位置對應一個確定的數(shù)字碼，因此它的示值只與測量的起始和終止位置有關(guān)，而與測量的中間過程無關(guān)。can2.0編碼器詳情旋轉(zhuǎn)編碼器隨著工業(yè)操控的不斷發(fā)展，并且又有了新的需求，使用也越來越普遍。</p><div

style="text-indent:25px">多圈編碼器另一個優(yōu)點是由于測量范圍大，實際使用往往富裕較多，這樣在安裝時不必要費勁找零點，將某一中間位置作為起始點就可以了，而較大簡化了安裝調(diào)試難度。編碼器在長度定位方面的優(yōu)勢明顯，已經(jīng)越來越多地應用于工控定位中。編碼器分為值型和增量型。目前編碼器的價格大約是增量型編碼器的4倍以上，國內(nèi)市場上70%的應用是價格相對經(jīng)濟的增量型編碼器，主要應用在如包裝、紡織、電梯等行業(yè)中*要求測量轉(zhuǎn)速及位置測量要求不高的機器設(shè)備上。而在高精度機械設(shè)備或鋼鐵、港口及起重等重工業(yè)行業(yè)，由于對測量的精度要求相對較高，更多情況會使用編碼器。在這些重工業(yè)行業(yè)應用中，由于工況比較惡劣，所以對編碼器的抗沖擊和振動等指標要求較高。</p><p style="text-indent:25px">編碼器的脈沖信號的輸出頻率與轉(zhuǎn)速成線性比例關(guān)系的。隨著轉(zhuǎn)速的增加編碼器的輸出信號頻率增加。從故障現(xiàn)象看，這是典型的信號長線傳輸高頻特性不良造成的問題。通過線路及電纜的情況調(diào)查，基本將問題鎖定在編碼器傳輸線路上。問題的解決：改善信號電纜的輸出特性；減小高頻信號的傳輸距離；信號電纜的空間排布；增強編碼器輸出帶載能力等?；诂F(xiàn)場實際情況，重新整理信號電纜的傳輸距離（從130m減小到90m）后，較大減小了信號傳輸?shù)木嚯x，極大的改善了長線高頻信號傳輸?shù)奶匦?。脈沖編碼器的結(jié)構(gòu)：在一個圓盤的圓周上刻有等間距線紋，分為透明和不透明的部分，稱為圓光柵。</p><div

style="text-indent:25px">隨著機械設(shè)備自動化程度的提高，編碼器產(chǎn)品的應用領(lǐng)域也越來越普遍，客戶已不再滿足于編碼器*能將物理的旋轉(zhuǎn)信號轉(zhuǎn)換為電信號，還要求編碼器集成度更高，產(chǎn)品更加耐用，并且希望能在編碼器中出現(xiàn)更豐富的接口方式，使更多的設(shè)備實現(xiàn)智能化。目前整個工業(yè)市場中生產(chǎn)安全及通信安全越來越被重視，國家層面也開始對產(chǎn)品的安全性能提出要求，編碼器在安全標準方面也有相應規(guī)范，但由于國內(nèi)編碼器市場對產(chǎn)品技術(shù)要求相對較低，客戶對中低端產(chǎn)品更為青睞。當使用編碼器處理多圈位置應用時，同樣需要設(shè)備系統(tǒng)，在獲取反饋位置編碼的同時，對旋轉(zhuǎn)圈數(shù)進行累加計算。can2.0編碼器詳情</p><p

style="text-indent:25px">打印機掃描儀的定位就是用的增量式編碼器原理，每次開機，我們都能聽到噼哩啪啦的一陣響，它在找參考零點，然后才工作。這樣的方法對有些工控項目比較麻煩，甚至不允許開機找零（開機后就要知道準確位置），于是就有了編碼器的出現(xiàn)。編碼器光碼盤上有許多道刻線，每道刻線依次以2線、4線、8線、16線.....編排，這樣，在編碼器的每一個位置，通過讀取每道刻線的通、暗，獲得一組從2的零次方到2的n-1次方的2進制編碼（格雷碼），這就稱為n位編碼器。這樣的編碼器是由碼盤的機械位置決定的，它不受停電、干擾的影響。多圈編碼器現(xiàn)貨</p></p><br
