1. 概要 GENERAL
EPP1000系列电-气阀门定位器的作用是把调节装置输出的电信号变成驱动调节阀动作的气信号，而且具有阀门定位功能，即克服阀杆摩擦力，抵消被调价质压力变化而引起的不平衡力，从而使阀门开度对应于调节装置输出的信号，实现正确定位。由于本定位器具有防爆结构，故能使用于爆炸场所。
The EPP1000 Series Positioner, mounted on a pneumatic actuator,moves the actuator by receiving DC 4~20mA signals from a controller.Also, the function of detecting and returning the actuator displacement
provides accurate positioning in response to DC 4~20mA signals.The EPP1000 Series can be used in an explosive ambient due to
explosion proof stucture. |
