EP800 系列电-气定位器与气动执行机构配套使用,输入4~20 mA DC 的信号转换成输出空气压力,控制执行机构的动作。同时根据执行机构的行程进行反馈,从而使执行机构的行程能按控制信号进行精确定位。
EP800 系列电-气定位器能用于单动作型和双动作型执行机构。
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.
