Edwards (formerly BOC Edwards) Vacuum Gauges and Vacuum Calibration

Edwards IGC ION Gauge Controllers

5 x 10 ^-3 to 2 x 10 ^-11 mbar

The Edwards (formerly BOC Edwards) Ion Gauge Controller (IGC) provides all the power, control and signal conditioning required to run one or two ion gauge heads. When connected to a BOC Edward Active Gauge Controller (AGC) the user has full control of the ION gauge functions from the AGC front panel. This includes features such as automatic emission current selection and interlock with other gauge types. Alternatively, the IGC can be linked directly to a control system such as a PLC to give the OEM or system builder direct access to control points and signal outputs.

Edwards IGC ION Gauge Controllers

Features and Benefits

Wide measuring range – electron beam degas versions
Selection of heads available
- Choice of electron beam degas, nude or glass encapsulated, tungsten or thoriated iridium filaments
Flexible cabling system
- Ion gauge cables are available in 2 and 3m lengths including bakeable versions. Active gauge cables to link IGC and AGC are available in lengths up to 100m
Vacuum interlock through an auxiliary high pressure gauge
- To protect the ion gauge from accidental operation at high pressure it can be interlocked through an active Pirani or thermocouple gauge connected to the IGC or AGC
Ratiomatic measurement accuracy
- Improved measurement accuracy
- allows soft start on filament power up giving an added degree of filament protection
Choice of Edwards interface or parallel command and status port (PCSP)
- Allows connection to BOC Edwards Active Gauge controllers
- PCSP: 15 way D-type connector giving access to all control input and signal outputs
