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.
Electric actuators, like pneumatic actuators, are an important part of the control system.
Actuators play a very important role in modern production process automation.
he rapid development of power electronic technology, computer technology and communication technology will definitely promote the rapid development of electric actuators.
According to the different control media used by the actuator, it can be divided into three types: pneumatic, electric and hydraulic actuators.
Actuators are an important part of process control. The role of the actuator is to receive the control signal sent by the controller, change the flow of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. The action of the actuator is realized by the output signal of the regulator through various actuators. The actuator consists of an actuator and an adjustment mechanism.
