there r differant type of pressure devices Barometers,Manometers,U-Tube Manometer,Well Type,Bourdon Tube Gauge,Micromanometer,and Elastic Pressure Transducers
pressure transducers electrically detect the gage pressure of fluids like oil and water or gases like air. pressure transducers have sensing elements for transducers, and they can be used for consistent, highly reliable measurements over long periods of time.
