Overview

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

Technology

The AIM 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 Gauge is 1 x 10-8 to 1 x 10-2 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 AIM 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 10-8 mbar. Typical processes range from general vacuum through industrial coaters and furnaces to scientific instruments and semicon.

Features and Benefits

  • Drive electronics combined in the gauge head which reduces the system cost and saves valuable rack space
  • Wide-ranging, regulated, internal power supply which runs from standard d.c. power supplies of +13.5 to +36 V with a good tolerance to voltage fluctuations
  • Standard analog output of 0 to +10 V d.c. and gauge identifier allowing easy interface with a computer or plc and fault output indication
  • Low output impedance and integral Faraday shield provides high level of noise immunity and permits long cable runs (up to 100 m)
  • Interchangeable body tube allows for rapid tube replacement without pre-calibration
  • Electrode service kit allows user cleaning and maintenance
  • The Unique striker design ensures rapid striking even at high vacuum or in contaminating conditions
  • CSA, C/US approved
