The difference between Gauge and Sealed pressure transmitters lies in what reference pressure they use to measure pressure.
1. Gauge Pressure (G or GP)
Measures pressure relative to atmospheric pressure.
Zero gauge pressure means it's equal to the current atmospheric pressure.
Most common in everyday applications (e.g. car tires, 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 35 + 14.7 = 49.7 psi.
Used when atmospheric pressure changes aren’t critical to your process.
2. 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:
You bring a sealed gauge transmitter from sea level to a mountain. It still assumes 1 atm = 14.7 psi, even though the actual atmosphere might be lower.
Used in environments where atmospheric pressure is not consistent but doesn't need absolute accuracy (like remote sites).
