數字精密電子定位系統
peps®II是在TMC的**peps®(精密電子定位系統)基礎上建立的并進行了改善。通過添加一個新的數字控制器使pep®II的使用更簡單,提供了更多的功能,并且具有改進的用戶界面。peps®II是用于TMC氣浮隔振系統的數字式非接觸高度控制系統。這種系統通常包含機械高度閥和機械高度傳感裝置,其應用范圍從用于半導體制造設備提高沉降時間和增加產量,到要求噪聲性能和穩定的平臺的精密實驗室環境。
特性和好處
?數字控制,用戶友好的LCD接口
?用于Gimbal Piston,CSP和Maxdamp的非接觸式電動氣浮高度控制隔振系統
?z軸位置重復性:10微米
?通過消除常規機械高度控制系統的杠桿接觸點改善隔振性能
?氣浮前饋功能使z軸對x - y軸運動的反應達到zui 小化
?可選“VX”功能集成慣性傳感器,用于垂直隔離器共振主動阻尼
?比例電子閥。通過使用“開關”或傳統電子閥門無脈沖噪聲引入
