- Gauge Pressure:
Gauge pressure is measured relative to atmospheric pressure at a given location. It indicates the pressure above atmospheric pressure, meaning a reading of zero gauge pressure corresponds to the ambient atmospheric pressure. This is commonly used in industrial applications, such as steam and gas systems.
- Absolute Pressure:
Absolute pressure is measured relative to a complete vacuum (zero pressure). It accounts for the total pressure, including atmospheric pressure. This measurement is essential in applications like altitude monitoring and vacuum systems, where precise pressure readings are required.
- Differential Pressure:
Differential pressure represents the difference between two points in a system, often separated by a barrier. This measurement is crucial for monitoring flow rates, filtration efficiency, and system performance in various industries.
