Psia and psig
WebNov 16, 2024 · PSIA is a term that describes the absolute pressure in PSI, including the pressure of the atmosphere. Examples of How to Calculate PSIG and PSIA. Note that PSIG is always lower than PSIA. The formulas to describe the relationship are: PSIG + 1 atm = PSIA and PSIA – 1 atm = PSIG (where atm is atmospheric pressure). WebOur PSIG (gauge) sensors utilize a vent tube in the cable to allow the device to reference atmospheric pressure. The resulting gauge pressure measurement reflects only the depth of submergence. We also offers a PSIS (sealed gauge) pressure sensor. This is an absolute sensor to which 14.7 PSI offset has been included to account for air pressure.
