423 Cold Cathode Vacuum Sensor – MKS

423 I-Mag Cold Cathode Vacuum Sensors

The 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 I-Mag® 423 vacuum sensor is lower-cost, more compact, and has a higher bake-out temperature.
