BCG450 Hot Ionization Gauges

ATM to Ultra High Vacuum TripleGauge®

The INFICON Bayard-Alpert Pirani Capacitance Diaphragm Gauge (TripleGauge®), BCG450, combines the advantages of three different technologies in a single, compact, economical package to measure process and base pressure from 5×10-10 to 1500 mbar (3.75×10-10 to 1125 Torr). 

The BCG450 is designed to take the place of three sensors (hot ion, convection enhanced Pirani and vacuum switch), thus reducing cost and valuable tool space.

Also available with PROFINET digital interface.

Advantages

  • BCG450 saves cost and tool space and reduces the complexity of vacuum measurement installation and setup
  • Gas-type-independent pressure measurement above 10 Torr provides more reliable loadlock control for any gas mixture
  • Pirani interlock protects the hot filament from premature burnout
  • Automatic high vacuum Pirani adjustment reduces operator interventions
  • Differential pressure measurement at atmosphere eliminates uncertainty related to atmospheric pressure changes
  • Easy-to-exchange sensing element with on-board calibration data guarantees reproducibility
  • Optional graphic display and Fieldbus interfaces available
  • RoHS compliance

Typical applications

  • Pressure measurement in Semiconductor process, transfer and loadlock chambers
  • Industrial coating
  • General vacuum measurement and control on systems in the low to ultra high vacuum range
