50mm Center Back Mount Plastic Case Vacuum Pressure Gauge Manufacturers
Description
A Vacuum Gauge is a pressure measuring instrument that measures pressure in a vacuum (i.e., in a vessel operating at sub-atmospheric pressure). Depending on the type of vacuum system and the required operating vacuum level, different vacuum gauges are required, often in combination with one another, to accurately determine and/or control the vacuum level of the chamber at any given moment in time.
Vacuum gauges are basic measurement components for vacuum furnace systems and can be found either in vacuum lines or connected directly onto the vacuum chamber. For all intents and purposes, a vacuum gauge is an instrument for measuring pressures below that of atmospheric pressure. There are several types of vacuum gauges, each engineered for a specific function over a specific range of vacuum pressure.
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.
