40mm Stainless Steel Case Brass Connection Pressure Gauge for Vacuum Pump
Description
This type of vacuum gauge does not measure the pressure directly as an area-related force, but indirectly by means of other physical variables that are proportional to the number density of particles and thus to the pressure. The vacuum gauges with gas-dependent pressure reading include: the decrement gauge, the thermal conductivity vacuum gauge and the ionization vacuum gauge having different designs.
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.
