The TELEVAC 7FC cold cathode ultra high vacuum gauge has a measurement range from 1 × 10-11 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 7FC is resistant to inrushes of gas. The design of this sensor allows for easy disassembly, enabling quick cleaning and extended use. The 7FC can be operated by the TELEVAC MM200 or MC300 rack-mountable controllers. These controllers automatically operate the cold cathode to provide a full-range vacuum measurement solution when the 7FC is used in conjunction with rough vacuum sensors.

7E Double Inverted Magnetron Cold Cathode Sensor – This sensor has a measurement range from 1 × 10-8Torr 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. The 7E can be operated by several TELEVAC controllers, including the MM200, MC300, and MP7ER. The MM200 and MC300 controllers automatically operate the cold cathode to provide a full-range vacuum measurement solution when the 7E is used in conjunction with rough vacuum sensors.
MM200 Vacuum Sensor Controller – The MM200 controls any TELEVAC vacuum sensor including cold cathode, convection, diaphragm, hot ion, and thermocouple sensors. It also has optional features including up to 8 relay set points and RS-232/RS-485 communications. The large, bright LED display makes it easy to read from a distance. The MM200 is a modular unit, allowing customers to choose a vacuum sensing solution specific to their needs.
MC300 Vacuum Sensor Controller – The MC300 controls up to two TELEVAC thermocouple or convection rough vacuum sensors and an optional cold cathode or mini hot ion high-vacuum sensor. It features 4 relay set points and large, bright LED displays, making it easy to read from a distance.
