Difference Between Gauge, Absolute, Differential, and Sealed Pressure:
Gauge Pressure:
Gauge Pressure is obtained by removing the Atmospheric Pressure in the absolute pressure. this process is done above the atmospheric pressure.
We can measure this type of pressure by using Bourdon gauge.
Absolute Pressure:
Absolute pressure is defined as the addition of both Gauge pressure and atmospheric pressure. This is obtained when we measure above the absolute zero pressure.
It required an Android barometer to measure the absolute pressure.
Differential pressure:
Differential pressure explains the pressure difference present in the system, which is obtained by measuring in between two different points.
Vacuum Pressure:
Vacuum pressure is obtained by eliminating the absolute pressure in the atmospheric pressure, this is obtained by measuring below the atmospheric pressure.
Atmospheric Pressure:
This is the normal pressure of air present on the surface area. Eliminating a gauge pressure from absolute pressure, we can obtain an atmospheric pressure.
