50mm Pressure Gauge For Vacuum Pump Painted Steel Case Brass Tube
Description
A vacuum gauge measures pressure below the atmospheric pressure. Normally the atmospheric pressure is set as zero and the vacuum pressure is given in negative values, so -1 barg (-15 psig) means complete vacuum.
Most pressure gauges make use of a bended tube. This tube is called a Bourdon tube. The tube deflects slightly under a pressure differential between the medium and the atmosphere. The tube deflection is converted via a mechanism to a needle position on the dial.
This design principle is in fact the same for normal and vacuum pressure gauges. If you want to learn more about the design principles, you can read our full article about pressure gauges.
Applications
Practically all industries make use of vacuum, from pick and place in the automotive industry, food & beverage, manufacturing, pharmaceutical, chemical, nautical, etc. The vacuum gauges are important devices to ensure optimal performance and safety of the system. They may be used for pick-and-place applications, keeping the workplace clean from pollutants, transport materials, etc.
