ENGR-162/12 - Benjamin W. Kidd Definitions Pressure Gauge – Device that displays the pressure of an air system. Compressor – Device which pressurizes air for use in air powered devices such as tools and pneumatic cylinders or to be stored in a tank. Air Pressure Gauge www.lowes.com ENGR-162/12 - Benjamin W.

Gauge and Absolute Pressure Gauge Pressure – Air pressure measured relative to surrounding pressure (I.E. – what you see on a gauge) Absolute Pressure – Air pressure measured in reference to a vacuum. Note: Absolute pressure at sea level is equal to 1 Atm = 14.7 PSI ENGR-162/12 - Benjamin W. Kidd
