Bayard-Alpert style hot-cathode ionization vacuum gauges
These gauges operate using a heated cathode that emits electrons to ionize gas molecules inside the vacuum system. The ion current produced is proportional to the system pressure, enabling accurate measurement across high and ultra-high vacuum ranges. The Bayard-Alpert grid design also minimizes X-ray limit errors, ensuring more precise low-pressure readings.
Benefits
- Reliable and economical vacuum measurement suitable for a wide range of applications
- Choice of single or dual filament designs to match specific process needs
- Burn-out resistant filaments extend operational life and reduce maintenance costs
- Degas functionality helps maintain gauge accuracy over time
- Supports measurement from high vacuum to ultra-high vacuum conditions
