Edwards Active Gauge Controller with Pirani Gauge and ASG2000 Active Strain Gauge

Edwards AGC Active Gauge Controller Triple Display, D38660000, 6 CM inputs

The Edwards Active Gauge Controller (AGC) is used with the Edwards Active vacuum gauges. The AGC interfaces directly to 3 or 6 (depending on the AGC model) Active vacuum gauges providing a comprehensive control and display system.

You can use any of the following gauges with the AGC D38660000:

Gauges can be turned on and off manually from the front panel or can be programmed to switch on automatically when the pressure measured by another gauge reaches a pre-set level.

The display and control features of the AGC are accessed through a menu structure. You move through the menu with simple keystroke combinations entered from the front panel. Security of gauge settings is achieved by a two level password system which restricts access to certain areas of the menu. In addition, the AGC can be interfaced to other microprocessor and data acquisition systems through an optional serial RS232 communications link.

The AGC Controller has 6 outputs which can be programmed as gauge pressure set points and so used to control the operation of auxiliary equipment. An optional relay board can be fitted which increases the load capability of these outputs.

The AGC Controller has one chart recorder output for each gauge channel (3 or 6 depending on version). These give an analogue output in the range 0 to 10 V corresponding to the pressure measured by the gauge.

Active Pirani Gauge pn D0217-4000

The Edwards Active Pirani Gauges (APG).  These gauges have a measuring range from atmosphere to 1 x 10-4 mbar and  combine the gauge head and controller in one compact active unit. The well proven, cost effective and reliable Pirani range has a substantial user base with a successful track record in the measurement of rough and backing pressures across a broad spectrum of applications. 

ASG2000 Active Strain Gauge pnD3572-8000, ASG16

The Edwards Active Strain Gauge (ASG) is a rugged, corrosion resistant diaphragm gauge which provides accurate, gas independent measurement from 2000 mbar to 1 mbar. It can be used as a standalone transducer allowing OEMs and system builders to develop low cost, flexible solutions to their vacuum instrumentation needs. Alternatively, it can be connected to the Edwards Active Gauge Controller where it can be combined with many other sensor types to provide a complete vacuum instrument solution.
