Understanding Pressure Measurement Types
1. Gauge Pressure (G or GP)
Measures pressure relative to atmospheric pressure. Zero gauge pressure means it's equal to the current atmospheric pressure. Common in everyday applications like car tires and water pumps.
Example: If a tire reads 35 psi (gauge), the actual pressure is 35 psi above atmospheric pressure (~14.7 psi at sea level), so the absolute pressure is 49.7 psi.
2. Absolute Pressure (A or AP)
Measures pressure relative to a perfect vacuum (0 psi). Doesn't change with altitude or weather, making it ideal for scientific research or altitude-sensitive processes.
Example: A vacuum chamber showing 0 psi (absolute) is a true vacuum. If the ambient atmospheric pressure is 14.7 psi, and a process is at atmospheric pressure, it will read 14.7 psi (absolute).
3. Sealed Gauge Pressure (SG or SGauge)
Measures pressure relative to a fixed (sealed) atmospheric pressure—usually sealed at 1 atm (14.7 psi). Works like gauge pressure but doesn't adjust with changes in local atmosphere (like elevation or weather).
Example: Bringing a sealed gauge transmitter from sea level to a mountain still assumes 1 atm = 14.7 psi, even though the actual atmosphere might be lower.
