The Vacuum Gauge Controller VGC083 A/B/C is a three channel gauge controller for vacuum pressure monitoring and controlling from atmosphere down to ultra-high vacuum. The industrial design of VGC083 in combination with a large selection of available passive gauge heads provides a flexible yet reliable and economical choice for vacuum applications requiring a wide vacuum measurement range. Due to the extended compatibility, VGC083 is the ideal solution for existing systems requiring direct drop-in replacements.

VGC083 can be configured to control and read-out up to 3 passive gauge heads among two types of passive sensors design types: one ionization gauge (hot cathode or cold cathode), plus two Pirani gauges. 

• VGC083A is designed for use with one passive hot cathode ionization Bayard-Alpert BAG050 (nude) or BAG055 (compact metal enclosed) gauge head and two convection enhanced Pirani PGE050. 
• VGC083B can host one passive hot cathode ionization Bayard-Alpert BAG051 (nude) or BAG052/053 (glass tube) gauge head and two PGE050. 
• VGC083C can control one passive inverted magnetron cold cathode MAG050/060 gauge head and two PGE050.  

Six single pole setpoint relays are assignable to any of the gauge heads. Built-in RS232 and RS485 control interfaces are provided for system integration.

 

Advantages

• Flexible solution for vacuum pressure monitoring and controlling from atmosphere down to ultra-high vacuum
• Clear and simple operation with three individual bright LED displays
• Parameter, sensor and general settings with softkeys
• User selectable filament, degas electron bombardment or I²R resistive heating for gauge conditioning depending on gauge head type
• Three analog outputs, user assignable to a single gauge or to gauges combinations
• Six assignable single pole double throw setpoint relays
• Ion gauge overpressure protection: sensor 1 can be automatically turned on/off from sensor 2 or 3
• Remote digital I/O sensor and emission on/off, RS232 / RS485 serial communication
• Direct drop in replacement opportunity for Granville-Phillips^® Bayard-Alpert Gauge Controller 307 and accessories
