Edwards AIM S NW 25 Inverted Magnetron Gauge, D14641000

The Edwards AIM Active Inverted Magnetron Gauges (AIM) combine the gauge-head and controller in one compact Active AIM X unit. These gauges have proved to be rugged and reliable in a wide range of applications ranging from scientific instruments to industrial processes.

This gauge has a low external magnetic field making it suitable for use with sensitive analytical instruments or maglev turbo pumps. In addition, this gauge features a linear output for easy integration with a computer or PLC.

Technology

The Edwards AIM-S-NW25 Gauge is an inverted magnetron gauge head and gauge controller in a single compact unit. The gauge operates as a cold cathode ionisation gauge, in which pressure is measured indirectly as a function of the current that flows in a Townsend discharge maintained in the body tube.

The measurement range of the AIM-S-NW25 Gauge is 1 x 10-2 to 1 x 10-8 mbar.

The AIM Gauge requires a 13.5 to 36 V d.c. power supply: it has a 2 to 10 V d.c. analogue output which is related to pressure.

The Edwards AIM-X-NW25 Gauge is compatible with all of Edwards Active Gauge Controllers and with the appropriate versions of the Active Gauge Displays. Alternatively you can use an independent power supply for the AIM Gauge and you can read the AIM Gauge output signal with a voltmeter or an analogue-to-digital converter.

Applications

All vacuum applications requiring rugged and reliable pressure indication in the range 1 x 10-2 to 1 x 10-9 mbar. Typical processes range from general vacuum through industrial coaters and furnaces to scientific instruments and semicon.
