423 I-Mag® & 431 Cold Cathode Vacuum Pressure Sensors
Overview
Using an inverted magnetron design, 423 I-Mag® vacuum pressure sensors can operate at pressures as low as 10-10 Torr with the proper controller which is much lower than a traditional Penning cold cathode sensor. This increased pressure range makes the Cold Cathode sensors ideal for for OEM or industrial use.
- Wide pressure measurement range 10-10 to 10-2 Torr
- No adjustment in emission current or filament voltage required
- No need to degas the gauge and no filaments to burn out
- Sensor tubes can be mounted in any position without affecting reading
- Cleaning of sensor is easy with a demountable tube
