INTRODUCTION

Pneumatic Servo system has been designed to demonstrate the basic principles of Pneumatic Control
Engineering. Every component of the unit is visible, so as to enable the students to watch its operation directly
and clearly.
All the elements are mechanical and as such the student do not need any background of electronic circuit
function.
Input and output movements are visible and also seen over computer with the help of linear and rotary sensor.

FEATURES

1. First order / second order / third order / forth order system.
2. Input and output movements is recorded by strip chart recorder and also fed to PC.
3. Inertia wheel type loading arrangement.
4. Control action by flapper nozzle.
5. user friendly software for performance curve analysis.

RANGE OF EXPERIMENTS

1. Open Loop Test:
For the measurement of piston velocity for various settings of gain.
2. Responce of the piston for unit step input
3. Effect of viscous damping and spring.
4. Study of flapper nozzle action.
5. Sinusoidal / ramp / step input.
6. Study of first order / second order / third order / forth order system.
