Electric Actuators : Green solution against pneumatic and hydraulic actuators . As the industrial world becomes increasingly connected, the designer’s need for intelligent components that can communicate with each other and operate without the need for manual interaction is growing. Hydraulic- Pneumatic Actuators : Pneumatic linear actuators consist of a piston inside a hollow cylinder. Pressure from an external compressor or manual pump moves the piston inside the cylinder. As pressure increases, the cylinder moves along the axis of the piston, creating a linear force. The piston returns to its original position by either a spring-back force or fluid being supplied to the other side of the piston. Accuracy Requires expensive position sensing and precise electrohydraulic valving to implement. Has tendency to creep. Hydraulic linear actuators operate similarly to pneumatic actuators, but an incompressible liquid...
