Display and operating unit for active sensors


Basic active gauge controller

Operating units for active sensors

To integrate the active sensors within system controllers additional display and operating instruments are needed. These provide the transmitters with the necessary supply voltage or to locally display the measured values. For such applications Leybold Vacuum offers different instruments. The basic DISPLAY line and the advanced GRAPHIX line are designed each for a broad range of applications. 

The DISPLAY vacuum controllers are universal controllers for the connection of active vacuum sensors for direct pressure measurements in the range of 10-9 mbar to 2000 mbar. This covers pressure reading and control for the majority of vacuum processes so is great for multiple applications. 

The DISPLAY series active gauge controllers are universal 1 or 3 channel displays and operating units with persistent display of all measurement channels, suited for the active sensors of the THERMOVAC TTR series, linear sensors of the DU series, and PENNINGVAC PTR series.  

Display range from 5 x 10-9 to 2000 mbar (0.75 x 10-9 to 1500 Torr)

Readout selectable between mbar, Torr or Pascal

Adjustable switching thresholds with variable hysteresis, floating changeover contacts and visual indication of the switching status in the display

Option of entering gas correction factors

Separate chart recorder outputs 0 – 10 V for each measurement channel

Compact bench top enclosures which can also be rack mounted for fitting into 19", 2 or 3 HU racks


The DISPLAY ONE is the single channel display unit for the transmitters from the THERMOVAC series, linear sensors of the DU series, and the PENNINGVAC PTR 90 series. The 7 segment display clearly displays the gauge pressure in a compact and cost-effective unit, and the chart recorder output enables you to record the gauge pressures during testing.

The DISPLAY THREE operates and displays units for the transmitters from the THERMOVAC TTR series, PENNINGVAC PTR Series and DU series. All channels are displayed simultaneously, with three 7 segment display lines. And with the ability to connect multiple gauges, it can work with all PTR gauges as it can control the turn on/off point of the PTR 225 pure cold cathode gauges.
