The 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.
This gauge features a linear output for easy integration with a computer or PLC.

Features and Benefits

  • Drive electronics combined in the gauge head which reduces the system cost and saves valuable rack space
  • Low output impedance and integral Faraday shield provides high level of noise immunity and permits long cable runs (up to 100 m)
  • Low magnetic field version - XL - for sensitive applications e.g. mass spectrometry and electron microscopy.
  • Interchangeable body tube allows for rapid tube replacement without pre-calibration
  • CSA, C/US approved
  • 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
  • Electrode service kit allows user cleaning and maintenance
  • The Unique striker design ensures rapid striking even at high vacuum or in contaminating conditions
  • Extended pressure range


  • 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.
