347 Stabil-IonVacuum Transducers
The stability, accuracy, and reliability of the Granville-Phillips® 347 Stabil-Ion® Vacuum Gauge are the results of many years of testing and design. Stabil-Ion gauges are the only high vacuum process control gauge that do not change calibration over time. These compact, convenient and reliable vacuum transducers mount the controller electronics directly on the gauge.
- Absolute measurement from 10-10 to 0.02 Torr
- Superior Stabil-Ion® Gauge performance in a compact package
- Dual gauge filaments that increase equipment uptime
- All metal design that eliminates glass and provides high immunity to RF
- Modular design that allows for quick and easy gauge replacement
Rugged Stainless Steel Enclosure
The stainless steel enclosure prevents grid and filament damage during mounting and eliminates the risk of glass breakage.
The Filaments are tensioned so they stay precisely positioned to maintain calibration.
Electrostatic shields completely surround the electrode structure to provide a stable, accuracy enhancing electrical environment.
Precision-Wound, Stress-Relieved Grid
The Precision-wound, stress-relieved grid retains its original shape even after high-temperature degassing, thus reducing measurement errors.
Vacuum Fired Components
The Stabil-Ion gauge is designed, constructed, and processed to minimize outgassing. The gauge is never touched by bare hands during manufacturing.
Choice of Range and Dual Filaments
Available as extended range or ultra-high vacuum with burn-out resistant yttria-coated iridium filaments. Unscheduled down time is avoided by using the second filament as a back-up until the gauge can be replaced during the next routine maintenance cycle.
