IGC5
ION GAUGE
Ion Gauge 1x Dual filament UHV. Thoria- or Yttria-coated Iridium filaments
Filament Drive Constant current dc (4A/10V)
Emission Control Microprocessor controlled precision PID control
Manual Emission User selections: 0.05, 0.1, 0.15, 0.25, 0.4, 0.6, 1, 1.5, 2.5, 4, 6, 10mA
Auto-emission Emission is automatically adjusted for optimum performance at measured pressure
ION GAUGE CONTROLLER
Emission features Soft-start. Optional "new filament" setting to permit gentle heating. User-definable min & max emission 
Degas Ramped low/mid/high power
Degas Features User-defined ramp/soak periods. User-defined pressure suspend to allow vacuum recovery
Degas Pressure Continuous measurement during degas
Degas on/off No interruption to pressure measurement during degas start/stop
Electrometer Effective Range: 0.1pA to 1mA; equates to 1x10-13 to 1 mbar (gauge dependent). High thermal stability, low drift
Sensitivity 1.0 to 99.9 (resolution 0.1)
Pump-down User-defined auto pump-down: backing gauge dependent ion gauge start-up pressure; trip allocation for external events (valves...), delay time, restart time etc
SECONDARY GAUGE PIRANI
Built in Supports ZPVG521
Number of Modules 1 module - with optional second module to run two ZPVG521
BAKE-OUT CONTROL
Built in Type K thermocouple. Standard mini-thermocouple connector
Range Room temperature to 500°C (16 bit resolution)
Bake-out Functions Precision CJC
Reproducibility <±0.2°C. Absolute <±2°C. User calibration available
6x ramp/soak steps, each up to 99.9 hours duration
Individual trip allocation for power switching
User-defined pressure interlocking (ramp suspend/time suspend/abort)
User-defined temperature hysteresis
Optional auto-degas at end of bake-out
INTERLOCK HUB
Trips 7 (4x SPCO relays 1A24Vdc/ 0.5A125Vac + 3x NPN open collector 100mA/12Vdc)
Trip assignments Individually assignable: external interlock to any ion or backing gauge, ion gauge status (on, off, degas), bake-out power switching, pump down external drive
Digital Inputs 2x opto-isolated inputs. 3-30Vdc; 2.4kΩ input resistance
Digital Input assignment External interlock as trip for ion gauge; control over ion gauge on/off and degas either via input state or toggle state, bake-out trip, pump-down trip, backing gauge operation
Interlock Response times 0.2 sec max. Typically <0.1sec
ANALOGUE OUTPUT
Output Full scale range: -0.2V to 10.2V (12 bit resolution). User-definable min and max
Accuracy and reproducibility Precision reference-based:  <±0.2%
Assignment Ion gauge (emission and sensitivity corrected), any secondary gauge, gauge combinations, bake-out temperature
Functionality User-defined voltage range, assigned pressure/temperature range, lin or log relationship
