355 Micro-Ion® Hot-cathode Bayard-Alpert Vacuum Sensors
Overview
Granville-Phillips® 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauges are the smallest Bayard-Alpert style gauges. They are more rugged and wider range than glass gauges. In addition, they generate less heat and provide greater burnout resistance.
- Small size that allows for easy installation in complex, tightly packed vacuum systems
- Rugged, all-metal design that eliminates costly downtime due to glass breakage
- Wider usable range compared to glass gauges
- Dual burn-out resistant filaments that provide long life for increased uptime
- Lower power requirements that result in less heat generation
