ATM to medium vacuum gauge RS485/ ANALOG

The INFICON Pirani Gauge Enhanced 500 (PGE500) is equipped with the latest digital convection enhanced Pirani technology available on the market. Due to the physical properties of convection this type of Pirani offers higher accuracy in the measurement range between 100 to 1000 mbar. The rugged gauge and sensor design in combination with many factory built in features, such as the bright, sharp and clear OLED display with integrated keypad, RS485/RS232digital interface and 4 selectable analog output signals makes the PGE500 a high value/low cost of ownership choice. All these features qualify this gauge for many applications where an economical vacuum measurement from low to high vacuum range is required.


  • Convection Enhanced Pirani Technology for wide measurement range and higher accuracy near atmosphere
  • All-in-One active gauge with built-in display, 2 set points, 4 analog output signals, and 2 digital interfaces
  • Bright digital OLED display with keypad for simple setup, calibration and operation
  • 4 optional analog output signals (3 user selectable, 1 Default)
  • Factory pre-set analog output signal or selectable via keypad
  • Factory pre-set display units or selectable via keypad
  • User programmable set point relays (factory pre-set on request for volume orders)
  • Gold plated tungsten filament
  • Mechanical strength, highly robust and less susceptible to mechanical shock and vibration
  • Choice of flange options
  • Compliance & standards: CE, RoHS
  • Direct drop in replaces most Granville-Phillips® Mini-Convectron® modules (GP275) (Granville-Phillips® and Mini-Convectron® are registered trademarks of MKS Instruments, Andover, MA)

Typical Applications

  • Fore vacuum pressure measurement
  • General vacuum measurement and control form low to the high vacuum range
