Part Number: 2-2146-052
The Televac 7FC cold cathode gauge (also called a vacuum pressure gauge or cold cathode ionization gauge) has an extremely wide measurement range from 10-11 Torr up to 10-2 Torr (making it an ultra-high-vacuum or UHV solution). This vacuum gauge makes indirect absolute pressure measurements by ionizing gas in the presence of a magnetic field. Unlike hot filament vacuum gauges, the 7FC cold cathode gauge is cleanable, contamination resistant, and isn’t as easily damaged by inrushes of gas.
The design of this vacuum gauge allows for bakeout without disassembly. The 7FC cold cathode ionization gauge can be operated by the Televac MX200 rack-mountable controller. Any vacuum controller will automatically operate the cold cathode to provide a full-range vacuum measurement solution when the 7FC is used in conjunction with rough vacuum sensors like the 2A or 4A. Active vacuum gauges can also be combined using the MX2A/MX4A and MX7B to provide full range vacuum measurement with the 7FC cold cathode ionization gauge.

Analog Output Behavior
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.
