Study Notes

Compressed Air System

Pressure

Defined as the force exerted per unit area
Measured in units of force per unit area (e.g. pounds per square inch, pascals)
In a compressed air system, pressure is created by the compressor and stored in the receiver tank

Gauge Pressure

The pressure measured relative to atmospheric pressure
Gauge pressure is the difference between the absolute pressure and atmospheric pressure
Measured using a gauge, which shows the pressure above atmospheric pressure (e.g. 100 psi gauge is 100 psi above atmospheric pressure)
Importance:
- Affects the performance of pneumatic tools and equipment
- Impacts the efficiency and safety of the compressed air system
