Vacuum Measurement and control systems - Edwards (formely known as BOC Edwards) vacuum guages

Edwards (formerly BOC Edwards) AIM Active Inverted Magnetron Gauge

10^-2 to 10^-9 mbar

BOC 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.

Features and Benefits

• Drive electronics combined in the gauge head

• Reduces the system cost

• Saves valuable rack space

• Wide-range, regulated, internal power supply
  Runs from standard d.c. Power supplies to +13.5 to +36 V
  Tolerant to voltage fluctuations

• Standard analogue output 0 to +10 Vd.c. And gauge identifier
  Easy to interface with a computer or plc
  Fault output indication

• Low output impedance and integral Faraday shield
  Provides high level of noise immunity

• Permits long cable runs (up to 100m)

• Interchangeable body tube
  Rapid tube replacement without pre-calibration
  Electrode service kit allows user cleaning and maintenance

• Bakeable Tube
  The DN40CF tube is bakeable to 300ºC (with the electronics removed)

• Unique striker design
  Ensures rapid striking even at high vacuum or in contaminating conditions

• Low external magnetic field versions (SL and XL)
  For sensitive analytical instruments (patented)
