Pressure measurement - Wikipedia

Pressure measurement - Wikipedia

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum.Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges.

Difference Between Gauge and Absolute Pressure Measurement

Difference Between Gauge and Absolute Pressure Measurement

Due to varying atmospheric pressure, gauge pressure measurement is not precise, while absolute pressure is always definite. Gauge Pressure. The most common pressure reference is gauge pressure which is signified by a 'g' after the pressure unit e.g. 30 psig. Gauge pressure is measured in relation to ambient atmospheric pressure.
