Type of Pressure Measurement

1. Absolute pressure

The pressure with absolute vacuum as the zero reference.

2. Positive pressure

A pressure more than atmospheric pressure based on atmospheric pressure.

3. Negative pressure

The pressure less than atmospheric pressure based on atmospheric pressure.

4. Differential pressure 

The difference between the two pressures.

5. Gauge pressure

Based on atmospheric pressure, a pressure more than or less than atmospheric pressure.
