ACTIVE ION GAUGE CONTROLLER RANGE 5 X 103 TO 2 X 10 11 mbar The Edwards Active Ion Gauge Controller (IGC) provides all the power, control and signal conditioning required to run one or When connected to a Edwards TIC Instrument Controller the user has full control of the ion gauge functions from the TIC 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 inputs and signal outputs. • Wide measurement range - Electron beam degas versions: • Selection of head available - Choice of electron beam degas, nude or glass encapsulated, tungsten or thoriated iridium • 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 • Vacuum interlock through an auxiliary low vacuum Active 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 • Ratiomatic measurement system - Improved measurement accuracy - Allows soft start on filament power-up giving an added degree of filament protection • Choice of Edwards interface (EHVI) or parallel command and status port (PCSP) - EHVI: allows connection to Edwards TIC Instrument Controller - PCSP: 15 way D-type connector giving access to all control input and signal outputs
