In order to suit uninterrupted development of the technical level in automatic control technology
the electric actuators have been fairly enhanced in aspects of accuracy
sensitivity
rapid response
and stability etc..But
there is still a gap existing between home-made electric actuators used at present and imported ones in aspects of sensitivity
accuracy
and intellectualization etc.of the positioner and the position transmitters.Through practical examples of using imported electric actuators in field bus control system of Guohua Ninghai Power Plant
the technical features of advanced electric actuators at present age have been presented.
