What is PSIG? For the sake of demonstration, this article will use PSI. Absolute pressure is measured relative to a full vacuum. The pressure of a vessel completely void of any air molecules would be 0 PSIA, while average atmospheric surface pressure at sea level is roughly Barometric pressure is measured on weather stations and data buoys using absolute pressure sensors; the data gathered by these sensors helps meteorologists track and predict severe weather like hurricanes and typhoons.

Gauge pressure is measured relative to ambient atmospheric pressure. A vessel completely void of any air molecules at sea level would be roughly All tools today have pressure gauges to help them monitor the operations. Even careers require the use of pressure measurements.

The careers of meteorologists, mechanical and civil engineers, pressure instrument technicians are few such examples. Skip to content No matter how the pressure is generated, it can be specified and measured in various ways, but it is mostly measured in PSI, i. What is PSI? What is PSIG? PSI is a measure relative to a vacuum. On the other hand, PSIG is a measure relative to the atmospheric pressure.

PSI is the force applied on a surface with one square inch of area and PSI Gauge is a measure of pressure, but a gauge measure only. PSI is mostly used in wastewater management, fuel storage, tire pressure and distribution, and so on, while PSIG is mostly used in the refrigeration and air conditioning industry.

It is mostly used in wastewater management, fuel storage and distribution, tire pressure, and so on.
