Pressure measurement glossary-pressure type(Absolute, Gauge, Differential) Gauge Reference Pressure or G - is a pressure measured relative to atmospheric or barometric pressure. Absolute Pressure - is one which is measured relative to a perfect vacuum. Barometric Pressure or Atmospheric Pressure - is Gauge Reference Pressure or G - is a pressure measured relative to atmospheric or barometric pressure. Absolute Pressure - is one which is measured relative to a perfect vacuum. Barometric Pressure or Atmospheric Pressure - is the total outside air pressure measured with reference to absolute vacuum. The pressure varies depending on geographical location, altitude and local weather conditions. For weather reporting purposes the barometric pressure is normally adjusted to a sea level value so that all locations can be compared independent of the altitude at each location Read More >>

What is absolute pressure Pressure is represented by defining absolute vacuum as zero. Gauge pressure is generally used. Absolute pressure is used for scientific calculations, etc., and is distinguished from gauge pressure by putting “abs” after the unit (for example, mmHg abs). Read More >>

What is gauge pressure Pressure is represented by defining atmospheric pressure as zero. Pressure higher than atmospheric pressure is positive pressure, while pressure lower than atmospheric pressure is negative pressure. Read More >>

The difference between absolute and gauge pressure To select the right pressure sensor for a specific application besides the pressure range first of all the type of pressure measurement has to be considered. Pressure sensors measure a certain pressure in comparison to a reference pressure and can be divided into absolute, gauge and differential devices. Read More >>

Types of pressure measurements, gauge, absolute, differential Piezoresistive pressure sensors can be classified in terms of pressure ranges they measure, temperature ranges of operation, and most importantly the type of pressure they measure. In terms of pressure type, pressure sensors can be divided into five categories: Read More >>
