Inficon / Leybold 230682V01 Graphix Three Universal Controller for Active Vacuum Sensors

The Inficon/Leybold 230682V01 Graphix Three is a universal controller for active vacuum sensors, delivering real-time measurement data across up to three independent channels. The 3.5-inch TFT touchscreen provides graphical curve display, bargraph visualization, and decimal readouts with zoom functionality across a measurement range of 1 × 10⁻¹⁰ to 2000 mbar (0.75 × 10⁻¹⁰ to 1500 Torr).

This controller accepts Leybold’s THERMOVAC, IONIVAC, PENNINGVAC, CERAVAC, and DU sensor series, plus active vacuum gauges from other manufacturers outputting linear or logarithmic 0–10 V signals. The intuitive menu interface supports six independently adjustable switching thresholds with variable hysteresis and floating changeover relay contacts rated 1 A / 30 V AC / 30 V DC. Each channel output can be freely assigned to individual measurement channels.
