903 Inverted Magnetron Cold Cathode Vacuum Transducer
Overview
Using the inverted magnetron design principle, the 903 Inverted Magnetron Cold Cathode Vacuum Transducer can operate at pressures much lower than a traditional cold cathode vacuum sensor. The 903 vacuum gauge has a second feedthrough for ion collection, ensuring accurate reading results. Its rugged design and ability to efficiently operate in harsh environments provide fast, dependable, and stable pressure vacuum measurement.
- Wide pressure measurement range from 3 x 10-10 to 5 x 10-3 Torr
- Integrated electronics for space and cost savings
- Isolated ion collector increases sensor’s resistance to effects of contamination
- High voltage can be deactivated at higher pressures to lower risk of sensor contamination
- One set point with LED status indicator is standard for process control
- No filament to burn out for low maintenance
