Televac® 7FC Double Inverted Magnetron Cleanable Cold Cathode Vacuum Gauge

Part Number: 2-2146-052


Compatible With: MX200, MX200 EthernetIP


Features and Benefits:

  • Low cost vacuum gauge
  • Easily cleaned cold cathode gauge for extended sensor lifetime
  • Durable double inverted magnetron gauge construction
  • Reliable cold cathode ionization gauge technology
  • Contamination resistant, resistant to inrushes of gas, and cleanable
  • Mountable in any orientation
  • Interchangeable with 7E, 7F, 7FCS
  • Excellent customer support

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 thermocouple vacuum gauge or 4A convection vacuum gauge.
