供應(yīng)意大利ELTRA編碼器：意大利Eltra公司成立于1985年，專業(yè)從事傳感器的開(kāi)發(fā)和生產(chǎn)。Eltra公司在生產(chǎn)傳感器的技術(shù)領(lǐng)域，
特別是在編碼器行業(yè)中，已有20多年的生產(chǎn)和銷售經(jīng)驗(yàn)。目前可以生產(chǎn)多達(dá)15，000多種型號(hào)的傳感器。意大利Eltra服務(wù)全球廣大客戶。
Eltra可以提供經(jīng)濟(jì)型編碼器，高性能增量式編碼器，重載型編碼器，以及行業(yè)應(yīng)用的多圈值編碼器，可以滿足多數(shù)客戶的性能需求。
特別是近年來(lái)推出的伺服電機(jī)上使用的編碼器，結(jié)構(gòu)精巧，產(chǎn)品的所有器件均為國(guó)外供應(yīng)鏈，使用母公司AVAGO的模組芯片，
使其運(yùn)轉(zhuǎn)可靠性大大加強(qiáng)，并且提高使用壽命。ELTRA編碼器包括:ELTRA值編碼器ELTRA增量編碼器ELTRA旋轉(zhuǎn)編碼器 
ELTRA拉線編碼器ELTRA光電開(kāi)關(guān)ELTRA接近開(kāi)關(guān)。其中ELTRA增量編碼器產(chǎn)品包括：ELTRA軸型編碼器ELTRA軸套型編碼器 
ELTRA磁編碼器ELTRA防爆編碼器ELTRA特殊增量型編碼器和ELTRA不銹鋼編碼器。
編碼器產(chǎn)生電信號(hào)后由數(shù)控制置CNC、可編程邏輯控制器PLC、控制系統(tǒng)等來(lái)處理。這些傳感器主要應(yīng)


用在下列方面:機(jī)床、材料加工、電動(dòng)機(jī)反饋系統(tǒng)以及測(cè)量和控制設(shè)備。在ELTRA編碼器中角位移的


轉(zhuǎn)換采用了光電掃描原理。讀數(shù)系統(tǒng)是基于徑向分度盤(pán)的旋轉(zhuǎn)，該分度由交替的透光窗口和不透光窗


口構(gòu)成的。此系統(tǒng)全部用一個(gè)紅外光源垂直照射，這樣光就把盤(pán)子上的圖像投射到表面上，該覆蓋著


一層光柵，稱為準(zhǔn)直儀，它具有和光盤(pán)相同的窗口。的工作是感受光盤(pán)轉(zhuǎn)動(dòng)所產(chǎn)生的光變化，然后將


光變化轉(zhuǎn)換成相應(yīng)的電變化。一般地，旋轉(zhuǎn)編碼器也能得到一個(gè)速度信號(hào)，這個(gè)信號(hào)要反饋給變頻器


，從而調(diào)節(jié)變頻器的輸出數(shù)據(jù)。故障現(xiàn)象:1、旋轉(zhuǎn)編碼器壞(無(wú)輸出)時(shí)，變頻器不能正常工作
，變得運(yùn)行速度很慢，而且一會(huì)兒變頻器保護(hù)，顯示“PG斷開(kāi)”...聯(lián)合動(dòng)作才能起作用。
