According to the different control media used by the actuator, it can be divided into three types: pneumatic, electric and hydraulic actuators.

he rapid development of power electronic technology, computer technology and communication technology will definitely promote the rapid development of electric actuators.

Actuators play a very important role in modern production process automation.

Electric actuators, like pneumatic actuators, are an important part of the control system.

The role of the position transmitter is to linearly convert the displacement of the output shaft of the electric actuator into a feedback signal, which is fed back to the input end of the servo amplifier.

The servo amplifier mainly includes an amplifier and two sets of thyristor AC switches.
