VGC031
Vacuum Gauge Controller
The Vacuum Gauge Controller VGC031 is a single
channel gauge controller for the INFICON Pirani Gauge
Enhanced PGE050. VGC031 acts as a convenient
power supply, control and readout, allowing
straightforward vacuum pressure monitoring andcontrolling 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 andoffers additionally RS232/RS485 digital interfaces. Thebright, sharp and clear OLED display with theintegrated keypad user interface rounds out this user
friendly vacuum gauge controller package. The housingof VGC031 allows panel mounting thus providing agreat rack space saving capability. The combination
VGC031 - PGE050 is the best choice for many vacuum
applications where economical vacuum measurementfrom atmosphere to high vacuum range is required.

ADVANTAGES• Displays and controls 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 MKS / Granville-Phillips® 375 and 475 controllers and 275 Convectron® gaugesensors and gauge cable (remote interface, relay and power connectors are different)
APPLICATIONS• General vacuum measurement and control from low to the high vacuum range*Granville-Phillips® and Mini-Convectron® are registered trademarks of MKS Instruments, Andover, MA
