Edwards active cold cathode ionization vacuum gauge pkg
This is a complete Edwards Active vacuum gauge package including a controller and a cold cathode gauge tube.
This is an Edwards Active Gauge Controller (AGC) vacuum gauge package with an inverted magnetron cold cathode gauge - complete and ready to be put to use.
The cold cathode gauge is used, but has been freshly rebuilt with new internal parts after cleaning the gauge tube housing. The sealing face of the flange shows some light scuffs and scratches, but nothing serious; it easily makes a "helium mass spec" tight seal when made up to another flange.
The gauge cable is new. It is not an original Edwards cable, but a commercially available Category 5e patch cable assembly with strain relieved connectors.
To test operation, this package was operated on a clean, turbomolecular pumped high vacuum system down to the 10-7 Torr regime. During this testing, the cold cathode gauge was not operated for extended periods of time, and was not ignited until after the system had been brought down to the low 10-5 Torr regime..
Controller (used but very clean condition):
* Edwards part number D386-54-000 (D38654000)
* single line digital display
* 6 gauge channels; multiple gauges may be operated simultaneously. (See controller manual for limitations when using other types of active gauges that have higher power requirements)
* 6 process control channels (open collector transistor outputs: 40 VDC, 100 mA maximum). These are individually assignable to any of the gauge channels, and can also individually be manually forced to "on" or "off" status through the front panel menu system. Front panel indicators show status of these process control channels.
* Can be configured so that one gauge (e.g., a Pirani gauge) automatically activates another gauge (e.g., a cold cathode gauge) at a specified pressure.
* analog outputs for all 6 gauge channels
* 90-265 VAC, 45-70 Hz mains operation
* A manual in .PDF format is available from Edwards (or from us; just ask).
AIM-S Active Inverted Magnetron cold cathode gauge (used but freshly-rebuilt condition):
* Edwards part number D146-41-000 (D14641000)
Cable to connect the gauge tubes to the controller (new condition):
* NOT original Edwards cable
* commercial Category 5e patch cable assembly with strain relieved connectors
