5200LA 气动薄膜式直行程执行机构

该系列是一种采用多弹簧结构，重量轻、体积小、性能高、输出力大的直行程气动薄膜式执行机构。其工作原理为：由调节仪表来的电或气信号经定位器转换而成的气压被输入到膜室内，作用于膜片上产生推力，使 输出轴移动，同时压缩弹簧直至和弹簧的反作用力相平衡，使输出轴到达预定的位置。位置控制也可以通过气信号（20～100 KPa）直接作用于膜片上来实现。该执行机构如与 KOSO 公司的定位器配合使用可以实现高精度的位置控制。

This Series provides high performance, high power diaphragm actuators of multi-spring type that are compact and light. Receiving pneumatic or electric signals, the unit balances the force created when diaphragm is airpressured through positioner and the force of compressed spring, so that the output shaft is controlled and placed at a set position. Control of position by pneumatic signals(20～100 KPa) directly applied on diaphragm is also possible.  Combination with KOSO positioner provides high accuracy position control.
