The 7E can be operated by the Televac® MX200 vacuum controller This
controller will automatically operate the cold cathode to provide a fullrange vacuum measurement solution when the 7E is used inconjunction with rough vacuum sensors like the 2A thermocouple or
4A convection.

The 7E cold cathode vacuum gauge has a measurement range from
1*10-8 Torr up to 1*10-2 Torr. It indirectly measures absolute pressure
by ionizing gas in the presence of a magnetic field. Unlike hot filament
sensors, the 7E is resistant to inrushes of gas. The design of this sensor
allows for easy disassembly enabling quick cleaning and extended use.
