Sealed Gauge. The reference pressure in a sealed sensor refers to atmospheric pressure trapped within the back of the diaphragm, with no vent path for pressure to flow in or out.
3 wrz 2020 · What is sealed gauge pressure? A sealed gauge pressure sensor measures pressure (P1) with reference to the atmospheric pressure (usually at sea level, 1013.25 mbar) as illustrated in the figure below. How does a sealed gauge pressure sensor measures pressure. This type of pressure sensors is less common compared to the other three.
Sealed gauged sensors measure pressure relative to one atmosphere at sea level (14.7 PSI) regardless of local atmospheric pressure. The same sensor can be used for all three types of pressure measurement; only the references differ.

by a pressure sensor’s internal strain gauge. A non-vented (or absolute) pressure sensor measures all pressure forces applied to the strain gauge, including atmospheric pressure. The back of an absolute pressure sensor is sealed from the atmosphere, and thus the front of the pressure sensor responds to both the pressure head of the water ...
