KJLC® 423 Series Cold Cathode Gauges & 943 Controller
Controller displays pressure from 10-10 to 10-2 Torr (mbar) using a high-visibility LED display.
Features
- Two types of analog output are standard, for remote monitoring of pressure
- Internal converter provides output that enables a simple log conversion from voltage to pressure over the entire operating range
- Fast-responding, buffered analog output is provided through the 15-pin accessory connector on the rear panel
- Inverted magnetron design
- Sensor can operate at pressures much lower than traditional Penning cold cathode sensors
- Ideal for UHV use
- No filament to burn out—sensor is not ruined by sudden inrushes of air and is resistant to vibration damage
- No need to adjust emission current or to degas the gauge, reducing response time to pressure changes
