431 & 423 I-Mag Cold Cathode Vacuum Sensors are based on the ionization probability of the gas, with the ionization as a result of a high voltage discharge of electrons. These cold cathode pressure vacuum sensors are based on an inverted magnetron design, for an increased measurement range. The dual feedthrough for ion collection is a unique feature, making the pressure reading more accurate than other cold cathode vacuum and pressure sensors.

The 431 vacuum sensor has a higher operating temperature and customized models are available. The I-Mag® 423 vacuum sensor is lower-cost, more compact, and has a higher bake-out temperature.

Features & Benefits:

  • Sensor tubes can be mounted in any position without affecting reading
  • No filaments to burn out
  • No need to degas the gauge
  • No adjustment in emission current or filament voltage required

Applications:

  • High energy physics
  • Analytical instruments
  • Laser production
  • Ion implantation
  • Mass spectrometry
  • PVD
