ELTRA編碼器產(chǎn)品分類(lèi)及應(yīng)用
Eltra已經(jīng)開(kāi)發(fā)諸多類(lèi)型的增量編碼器:各種機(jī)械安裝方式(實(shí)心軸、盲孔軸、通孔軸),各種分辨率、安裝法蘭方式、電路輸出方式,以各種應(yīng)用需要。
除了提供標(biāo)準(zhǔn)產(chǎn)品,Eltra也提供產(chǎn)品定制服務(wù),以滿(mǎn)足客戶(hù)的特殊需求,給予客戶(hù)360度服務(wù)。
旋轉(zhuǎn)編碼器是一種結(jié)合光學(xué)、電子、機(jī)械技術(shù)的產(chǎn)品。它用來(lái)反饋旋轉(zhuǎn)軸的位置和速度。
增量旋轉(zhuǎn)編碼器的定義源自于其工作原理:它能檢測(cè)從參考點(diǎn)實(shí)際點(diǎn)的增加量,和旋轉(zhuǎn)方向。增量編碼器可通過(guò)內(nèi)部的輸出電路輸出的脈沖信號(hào)感知旋轉(zhuǎn)的角度、角速度、角加速度。但是,每次開(kāi)機(jī)需要恢復(fù)系統(tǒng)零位。
Eltra易爾創(chuàng)編碼器在定位方面明顯地優(yōu)于增量式編碼器,已經(jīng)越來(lái)越多地應(yīng)用于工控定位中。型編碼器因其高精度,輸出位數(shù)較多,如仍用并行輸出,其每一位輸出信號(hào)必須確保連接很好,對(duì)于較復(fù)雜工況還要隔離,連接電纜芯數(shù)多,由此帶來(lái)諸多不便和降低可靠性,因此,編碼器在多位數(shù)輸出型,一般均選用串行輸出或總線型輸出,德國(guó)生產(chǎn)的型編碼器串行輸出zui常用的是SSI(同步串行輸出)。
多圈式編碼器。編碼器生產(chǎn)廠家運(yùn)用鐘表齒輪機(jī)械的原理,當(dāng)中心碼盤(pán)旋轉(zhuǎn)時(shí),通過(guò)齒輪傳動(dòng)另一組碼盤(pán)(或多組齒輪,多組碼盤(pán)),在單圈編碼的基礎(chǔ)上再增加圈數(shù)的編碼,以擴(kuò)大編碼器的測(cè)量范圍,這樣的編碼器就稱(chēng)為多圈式編碼器,它同樣是由機(jī)械位置確定編碼,每個(gè)位置編碼*不重復(fù),而無(wú)需記憶。多圈編碼器另一個(gè)優(yōu)點(diǎn)是由于測(cè)量范圍大,實(shí)際使用往往富裕較多,這樣在安裝時(shí)不必要費(fèi)勁找零點(diǎn),將某一中間位置作為起始點(diǎn)就可以了,而大大簡(jiǎn)化了安裝調(diào)試難度。多圈式編碼器在長(zhǎng)度定位方面的優(yōu)勢(shì)明顯,已經(jīng)越來(lái)越多地應(yīng)用于工控定位中。
