1. 概要 GENERAL
YT-1000系列电气定位器与气动调节阀配套使用，构成闭环控制回路。把控制系统给出的直流电流信号转换成驱动调节阀的气信号，控制调节阀的动作。同时根据调节阀的开度进行
反馈，使阀门位置能够按系统输出的控制信号进行正确定位。该电气定位器可用于单作用型（弹簧复位型）和双作用型气动执行机构。
The YT-1000 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 YT-1000 can be used with both springreturn and double acting
actuators.
