Vacuum (Measurement & Control)

Vacuum is a pressure below 1013 mbar commonly expressed in Torr. It can be measured either directly (pressure as a Force/Area) or indirectly through gas properties like thermal conductivity, viscosity, or electron ionisation. The Brooks gauge uses the direct method through the deflection between a fixed electrode at absolute vacuum and an inconel diaphragm reflectting proportionaly the pressure variations.

Those gauges can be digital (without potmeters) very reliable, stable and repeatable. They can be non hetaed for standard applications or heated at 45°C, 100°C or 160°C to make sure that condensation is fully eliminated.

They are very performaning in corrosive gases with a life expectancy 3 times greater than normal gauges.
