BPG400 ATM to Ultra-High Vacuum Gauge

 

The INFICON Bayard-Alpert Pirani Combination Gauge, BPG400, functions as two gauges in a single compact unit measuring from 5×10-10 mbar to atmosphere (3.8×10-10 Torr to atmosphere). Combining technologies reduces the complexity of installation, setup, and integration. Choose the BPG400 for affordable and repeatable process to base pressure measurements in one economic package.

Advantages

  • Extremely wide measurement range from 5×10-10 mbar to atmosphere (3.8×10-10 Torr to atmosphere)
  • Excellent repeatability in the process pressure range from 10-8 … 10-2 mbar of 5%
  • The Pirani interlock protects the Bayard-Alpert system from premature filament burnout and excess contamination from high pressure operation
  • Long-life yttrium oxide coated iridium filament
  • Optional graphic display and Fieldbus interfaces available
  • Automatic high vacuum Pirani adjustment reduces operator interventions
  • RoHS compliance
  • General vacuum measurement and control in the low to ultra high vacuum range

Typical Applications

  • Pressure measurement in semiconductor process and transfer chambers
  • Industrial coating
  • General vacuum measurement and control in the low to ultra high vacuum range
  • BPG400 Bayard Alpert Piran Gauge
