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 ...

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 ...

If you are like most of us in the HVAC industry, you are a hands-on person - you don‘t want to mess with a lot of theory, but just get in and get the job done. But a refrigeration system is different ...

Understanding atmospheric pressure is vital, newsroom meteorologist Justin Ballard said, because those giant H’s and L’s representing high and low air pressure systems on a weather map are meaningless ...

If you've watched a weather forecast and wondered what low pressure and high pressure systems are all about, we — and the barometer — have got you covered.

Keeping your car tires properly inflated is an easy maintenance chore that’s vital to your safety. Under-inflated tires build up excess heat as you drive, which can result in tire failure. With too ...

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 ...
