EP800 系列電-氣定位器與氣動(dòng)執(zhí)行機(jī)構(gòu)配套使用，輸入4~20 mA DC 的信號(hào)轉(zhuǎn)換成輸出空氣壓力，控制執(zhí)行機(jī)構(gòu)的動(dòng)作。同時(shí)根據(jù)執(zhí)行機(jī)構(gòu)的行程進(jìn)行反饋，從而使執(zhí)行機(jī)構(gòu)的行程能按控制信號(hào)進(jìn)行精確定位。

EP800 系列電-氣定位器能用于單動(dòng)作型和雙動(dòng)作型執(zhí)行機(jī)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.
