The MKS Instruments/Granville-Phillips 34001 Vacuum Gauge Controller measures vacuum pressure across nine decades, from below 1 × 10⁻⁹ Torr to atmospheric conditions. It accepts one ionization gauge and two Convectron gauges on a single instrument, delivering analog outputs and front-panel pressure readout. The controller integrates resistance heating degas with pressure-dependent interlocking, enabling safe tube conditioning in research and industrial vacuum systems.
Technical Specifications
• Pressure Range: Less than 1 × 10⁻⁹ Torr to atmosphere
• Ionization Gauge Inputs: 1 channel
• Convectron Gauge Inputs: 2 channels
• Display: Front panel pressure readout
• Analog Outputs: Pressure signal outputs
• Ion Gauge Cable Length: Up to 50 feet using standard cables
• Supported Gauge Types: Glass or nude Bayard Alpert (B-A) ionization gauges; Granville-Phillips Convectron gauges
– Key Features
• Resistance heating degas provided as standard function
• Degas interlock restricts heating to ion gauge ON state and pressures below 5 × 10⁻⁵ Torr
• Pressure readings unavailable during active degas cycle
• Hinged front panel conceals infrequently used controls, reducing footprint
• Half-rack form factor for equipment integration
• Remote input/output capability for automated system control
• Optional factory-installed process relay module available, supporting automatic ion gauge activation via Convectron channel 1 and selectable process relay output from either Convectron channel
– Typical Applications
Vacuum system monitoring in research laboratories, semiconductor manufacturing, and industrial processing environments requiring precise pressure measurement across extended dynamic ranges.
– Compatibility & Integration
The 34001 operates with standard ionization gauge cables for remote probe installation. Convectron gauge compatibility spans Granville-Phillips product lines. Optional process relay configurations enable autonomous gauge sequencing and external relay logic integration.
