BCG450 Bayard-Alpert Pirani Capacitance Diaphragm Vacuum Gauge - Triple Gauge™

The INFICON Bayard-Alpert Pirani Capacitance Diaphragm Gauge, 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.

BENEFITS

• 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 several fieldbus interfaces available (besides EtherCAT, other leading fieldbus systems are supported)
• 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
