here:
Figure 1 –Label (example)
1.2 Conforming Utilisation
The GRAPHIX controller is a display and operating unit with a graphic user interface for
sensors with an analogue or digital interface of the company Leybold GmbH or from other
manufacturers.
Depending on the version, the unit offers one or several channels, and it is used in
combination with the sensors from the series THERMOVAC, IONIVAC, PENNINGVAC and
CERAVAC as well as DU sensors for the measurement of pressures above and below
atmospheric pressures (vacuum).
It is also possible to use sensors made by other manufacturers by entering a variable
analogue logarithmic or analogue linear characteristic ranging from 0 –10 Volt.
Operate all connected sensors in agreement with the information given in the corresponding
Operating Instructions.
NOTICE:
Based on the technical data please check first whether your measuring
instrument is suited to your kind of application.
