A Vacuum Gauge is a pressure measuring instrument that measures pressure in a vacuum. Generally, this pressure is usually below atmospheric pressure.The atmospheric pressure is the standard pressure at sea level and is 101.325 kPa. It is more common to express pressure in bar or psi. Vacuum pressure (Pvac) is expressed in a negative value with respect to the atmospheric pressure.A vacuum is a space in which the pressure of a gas is low compared to the atmospheric pressure.
Application Of Vacuum Gauge
Vacuums are used in many industrial applications such as automotive, nautical, research and development, and manufacturing. They may be used to keep materials moving through the system or to keep the work area clean of pollutants. Gauges and instruments, such as sensors, are an important component to ensure the proper function and safety of the system and equipment.
