Setting up a pressure control process involves choosing between absolute pressure and gauge pressure. For a number of applications the choice could be to stick to an established convention, however ...

Pressure is the amount of force applied per unit area. Pressure can be measured by a pressure gauge, but it is important to know the type of pressure the gauge is reading. This article will cover the ...

Most engineers understand the concept of pressure. It’s a force, often measured in pounds, on a specific area. It is commonly listed in pounds per square inch (psi). But there are a variety of ...

When referring to absolute pressure, psia is used to label the pressure’s magnitude, and psig labels the pressure’s magnitude when referring to gauge pressure. Any time pressures are used in a ...

There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...
