431 & 423 I-Mag Cold Cathode Vacuum Sensors
(1.0x10-11 to 1.0x10-2 Torr)
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.
