ADVANTAGES
- Excellent long-term stability
- Digital RS-232 or RS-485 interface
- Bakeable all-metal sensor design
- Passive high vacuum sensor without ion- or heat source
The VIM-1 instrument is based on a robust spinning rotor gauge vacuum sensor that measures the pressure-dependent molecular drag on a magnetically levitated spinning steel ball.
APPLICATION
- Cryogenic and liquid gas vessels
- Vacuum insulation panel (VIP)
- Rate-of-rise outgassing testing
