Leybold Smart Monitoring Graphix TWO Series Pressure Controller with 2 Measurement Channels for Active Sensor Gauges.
Leybold PN 230681V01.

The Leybold Graphix Series TWO pressure controller represents the latest multipurpose pressure active sensor gauge controller. With complete coverage and control of vacuum pressures in the range between 1x10-10 to 2000 mbar or (0.75 X 10-10 to 1500 Torr) with an analog or digital interface. Depending on the model these units offer one to three channels of measurement. This Graphix TWO controller has 2 measurement channels and is able to read pressures from the following gauges, Capacitance, Piezo, Thermal conductivity, Cold Cathode Ion (Penning) and Hot Cathode Ion (Bayard-Alpert) from Leybold. These being THERMOVAC, IONIVAC, PENNINGVAC and CERAVAC as well as DU sensor gauges for the measurement of pressures above and below atmospheric pressures from Leybold Vacuum. It is also possible to use sensor gauges made by other manufacturers by entering a variable analog logarithmic or analog linear characteristic ranging from 0 – 10 Volt.

The Leybold Graphix Series TWO lets you touch and feel the difference with a new touch screen graphics display with intuitive user interface and easy to read curve and bar graph displays. The compact pressure controller allows for adjustable switching thresholds with variable hysteresis, floating changeover contacts and visual indication of the switching status in the display, freely assignable to the individual measurement channels. With pressure readouts in selectable measurements in mbar, Torr, Micron, Pascal or Psi. The controller is contained in a compact bench top housing with large color led displays.
