Project Description

Buil a motorised fully automatic Pneumatic Pressure Controller capable of achieving pressure up to 3600 kPa with the resolution of 1kPa.

Purpose :

To provide and maintain water pressure in a cylinder with the volume of about 5litres

To measure volume change

Pressure medium :

De-aired Water

Hardware consists of;

-Pressure cylinder with a piston driven by stepper/servo motor.


-Pressure sensor for pressure monitoring and feedback in the system.

-Stepper motor with a suitable gearhead

-Linear guide where the motor and gearhead sits on

Control and User interface System;

-PLC based system with a user interface to input the parameters and view the information for standalone operation.

-to develop a computer program where the pressure controller can be connected to the computer and program the pressure increment settings.


- Required to draft the design in Solidworks and make a simulation program.

We have a manual pneumatic pressure controller made by ourself as an example for this project. We will work together on this project as we have the engineering capacity to build the system. What we lack is the CNC skills.


The cost of the fabrication and parts sourcing will be on us. The budget stated below is to suggest the fee to hire you for your professional skills needed to accomplish the project as required.

The project delivery shall be;

-An automatic pneumatic pressure controller system that able to achieve presure up -to 3600 kPa with an accuracy of 1kPa.

-Integrated user interface to enter the parameters and display the information as well as external connection port to computer together with a custom software program to control the device via computer.

-Solidworks design files and simulation files

-PLC control algorithms
