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 ...

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 ...

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 ...

Piezoresistive (diaphragm-based) differential pressure sensors based on silicon comprise a thin silicon diaphragm in which resistors (connected together in a Wheatstone bridge) are lodged. If there is ...

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 ...

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 ...
