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 ...

coupled to a mechanical linkage that rotates the gauge pointer as the pressure in the tube changes its radius of curvature. The gauge measures the pressure difference between the inside and the ...

There are many ways to measure pressure, as well as different types of pressure. Here’s a look at some of the most common. Most engineers understand the concept of pressure. It’s a force, often ...

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 ...
