Features

Second Feedthrough for Ion Collection

A unique design feature of the Cold Cathode sensors is a second feedthrough for ion collection. In an ordinary single feedthrough design, any current leakage between the anode and ground would result in pressure measurement errors. Only the ion current from the cathode contributes to a measurement reading in a dual feedthrough design, making it ideal for process monitoring.

No Filament to Burn Out

With no filament to burn out, these cold cathode sensors are not ruined by sudden inrushes of air and are resistant to vibration damage. Additionally, there is no need to adjust the emission current or to degas the gauge, reducing response time to pressure changes.
