style="text-indent:25px">高精度角度編碼器電磁測角法：電磁測角法是近來幾十年發(fā)展起來的測角技術(shù)，主要應(yīng)用于角度的進(jìn)一步細(xì)分，使分度和測量范圍增大，提高儀器的分辨率。電磁式測角技術(shù)以圓磁柵和感應(yīng)同步器為表示，圓磁柵測角法是將圓磁柵連同被測件一起旋轉(zhuǎn)，利用放磁頭將磁柵上的記錄信號拾取出來進(jìn)行處理。按信號拾取的方式不同，放磁頭可以分為靜態(tài)磁頭和動態(tài)磁頭兩種。靜態(tài)時準(zhǔn)確度往往難以提高。動態(tài)時降低了對錄磁準(zhǔn)確度的要求，可以獲得較高的分度準(zhǔn)確度。高精度角度編碼器平時需要保養(yǎng)嗎？需要的。小角度測量編碼器費用</p><p

style="text-indent:25px">高精度角度編碼器的防護(hù)等級即是防塵防水性能，以IP，2位數(shù)字來表示，***位是防塵，第二位是防水，很多編碼器在現(xiàn)場用的好好的，可使用一段時間后就莫名其妙地?fù)p壞了，糾其原因，很多是編碼器的防護(hù)等級不夠。有些用戶以為工作環(huán)境沒有塵、水汽的問題，怎么還會損壞呢？其實編碼器在工作環(huán)境中，或編碼器工作與停機(jī)的變化中，由于熱脹冷縮的溫差而造成內(nèi)外氣壓差，防護(hù)等級差的編碼器（包括其他傳感器），會產(chǎn)生“呼吸性”水汽，由于內(nèi)外壓差水汽吸入編碼器，因時間的積累而損壞內(nèi)部光學(xué)系統(tǒng)或線路板，而損壞編碼器，這種內(nèi)部的損壞是慢性積累的，往往是如今還用的好好的，而內(nèi)部已積下隱患了。這種情況在工程項目中尤為突出，例如高溫、溫差大地區(qū)，高濕度地區(qū)，沿海地區(qū)（空氣中含鹽分），因此，工程項目所使用的編碼器，一定要使用標(biāo)準(zhǔn)工業(yè)級的高防護(hù)等級性能的編碼器。角度編碼器供貨商</p></p><br
