The Electro-Pneumatic Positioner NT-1000L is used for operation of pneumatic linear valve actuators by means of

electrical controller or control systems with an analog output signal of DC 4 to 20mA or split Ranges.

电-气阀门定位器NT-1000L是一种从控制器或控制系统中接收4~20mA直流电流信号，并向直行程气动执行机构输送

空气来控制阀门位置的装置。

There is no resonance at 5~200Hz.(在5~200Hz范围内无共振现象。)

The change of RA/DA Acting is convenient, it is able to apply to single or double acting actuator.

(正向和反向，单作用和双作用之间可方便转换。)

It is possible to prevent the hunting with orifice to the small size actuator.

(对于小型执行机构可通过缩小节流孔来防止振动。)

It is economical due to less air consumption. (空气消耗量少，经济性好。)

It is able to control the 1/2 split range with simple operation without replacement of parts.

(不用更换零件就可以实现1/2范围内的分程控制。 )
