I. Displacement sensors:

　　The servomotor cylinder is a cylinder-like mechanism, but its e projectile position is controllable.

　　The general position of the servomotor cylinder is around 0.05 mm, depending on the accuracy of the ballscrew and assembly precision.

　　Servo electric cylinder

　　The problem of accuracy can be solved by adding an external displacement sensor as a final feedback position. The accuracy of this control depends only on the accuracy of the displacement transducer, not on the mechanical and assembly accuracy. A good displacement sensor can achieve u-level accuracy.

　　II. Pressure sensors.

　　Existing electric cylinder in the operation and management process, the output of the driving rod is not stable, the internal staff did not carry out a good guided audit mechanism can make its output stable, there is no internal pressure detection technology equipment, so the operation of the electric cylinder driving rod can not be developed in a timely manner to control well. Therefore, it is necessary to solve the above analyzed problems by the electric cylinder with built-in pressure sensor.
