The Vacuum Gauge Controller VGC031 is a single channel gauge controller for the Pirani Gauge Enhanced PGE050. VGC031 acts as a convenient power supply, control and readout for PGE050, allowing straightforward vacuum pressure monitoring and controlling from atmosphere down to high vacuum (1.3×10-4  mbar). 

VGC031 supports a variety of technical features as 2 setpoint relays, 4 user selectable analog outputs and offers additionally RS232/ RS485 digital interfaces. The bright, sharp and clear OLED display with the integrated keypad user interface rounds out this user friendly vacuum gauge controller package. The housing of VGC031 allows straightforward panel mounting thus providing a great rack space saving capability. The combination VGC031-PGE050 is the best choice for many vacuum applications where economical vacuum measurement from atmosphere to high vacuum range is required. 


  • Displays and control wide measurement range from 1.3×10-4 up to 1333 mbar
  • Bright digital OLED display with keypad for simple set up and Operation
  • 4 user selectable analog output signals, 2 set point relays
  • RS232/RS485 digital Interface
  • Space saving design – 1/8" DIN panel mount housing for rack mount installation or as standalone unit
  • Powered through user supplied 12 to 28 V (dc) or by INFICON's VGC031 Power Supply
  • Compliance & standards: CE, RoHS
  • Replacement capability for Granville-Phillips® 375 and 475 controllers and 275 Convectron® gauge sensors and gauge cable (note: remote interface, relay and power connectors are different)
