EPB821,EPL801,EPL811電氣閥門定位器
| 1. 概要 GENERAL EP800系列電氣閥門定位器與氣動執(zhí)行機(jī)構(gòu)配套使用，輸入4~20mADC的信號轉(zhuǎn)換輸出空氣壓力，控制執(zhí)行機(jī)構(gòu)的動作。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 按控制信號進(jìn)行定位。EP800系列電氣閥門定位器能用于單動作型和雙動作型執(zhí)行機(jī)構(gòu)。 The EP800 Series Positioner, mounted on a pneumatic actuator,moves the actuator by receiving DC 4~20mA signals from a controller.Also, the function of detecting and returning the actuator displacementprovides accurate positioning in response to DC 4~20mA signals. The EP800can be used with both springreturn and double acting actuators. |
