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 ...

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 ...

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 ...

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...

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 ...
