Compact Gages
All of our compact gauges are ideally suited for general laboratory applications and system manufacturers. Each compact gauge offers an output voltage that is easily converted to any pressure measurement unit by one simple formula.
All of our compact gauges are ideally suited for general laboratory applications and system manufacturers. Each compact gauge offers an output voltage that is easily converted to any pressure measurement unit by one simple formula. We also offer both the SingleGauge and DualGauge full function controllers for our line of compact gauges. These units form a complete and easy-to-use pressure measurement and control system.

Two Gauges in One!

Pfeiffer Vacuum offers a dual gauge that's right for your application -

  • Bayard Alpert and Pirani gauges combined
  • Cold Cathode and Pirani gauges combined
  • Hot Cathode Ionization and Pirani gauges combined

By integrating two gauges in one compact design the benefits are:

  • One port, one gauge for reduced costs
  • Integrated electronics
  • Linear output across entire vacuum range
  • Output voltage that is easily converted to any pressure measurement unit
Bayard Alpert/Pirani Gauge:

The FullRange BA (Bayard-Alpert Pirani gauge) measures from 5 x10-'° mbar to atmosphere. This gauge has excellent repeatability of +/- 5% with +/- 15 % accuracy and is available with 25 ISO-KF, 40 ISO-KF and 40 CF flanges. It is ideal for base pressure monitoring and general vacuum measurement

Other advantages:

  • Degas feature to sputter away contaminants
  • Easy to replace sensor
  • Selectable switching threshold between Pirani and Hot lon sensor avoiding contamination
  • Automatic HV adjustment for the Pirani with Hot lon eliminates the need for Pirani adjustment due to contamination or aging

Cold Cathode/Pirani Gauge:

The FullRange CC (Cold cathode/Pirani gauge) combines these two gauges to read from atmosphere to UHV in one gauge. Complete with integrated electronics for a compact design.

  • One port, one gauge for reduced costs
  • Newly designed electronics dramatically reduces cleaning intervals for extended uptime
  • Integrated electronics
  • Linear output across entire vacuum range
  • Output voltage that is easily converted to any pressure measurement unit

Hot Cathode Ionization/ Pirani Gauge:

The Process Ion Gauge (Hot Cathode Ionization/Pirani gauge) measures vacuum from atmosphere to 10-6 mbar. The built-in automatic switchover virtually eliminates filament burnout so you can get better accuracy and stability in your thin film processes.

Advantages:

  • Highest stability, accuracy and reproducibility
  • Auto-degas protects gauge from contamination
