EP800 系列電-氣定位器與氣動執(zhí)行機構(gòu)配套使用,輸入4~20 mA DC 的信號轉(zhuǎn)換成輸出空氣壓力,控制執(zhí)行機構(gòu)的動作。同時根據(jù)執(zhí)行機構(gòu)的行程進行反饋,從而使執(zhí)行機構(gòu)的行程能按控制信號進行精確定位。
EP800 系列電-氣定位器能用于單動作型和雙動作型執(zhí)行機構(gòu)。
The EP800 Series Positioner, mounted on a pneumatic actuator, moves the actuator by receiving DC 4~ 20 mA signals from a controller. Also, the function of detecting and returning the actuator displacement provides accurate positioning in response to DC 4~ 20 mA signals.
The EP800 can be used with both spring-return and double acting actuators.
