2) usable measurement range 10 -2 to 10 -9 mbar
1.3 Technical Description
Based on a supply voltage of 24 V the PEG100 Penning
Gauge generates the internal supply voltages required
for operation of the integrated measurement system.
The PEG100 supplies a logarithmic representation of the
vacuum pressure by way of a voltage signal which ran-
ges from 0.66 V to 10 V. Moreover, the high tension
generated in the PEG100 can be switched on and off by
applying an external control voltage or by connecting an
external switch.
When the gas discharge in the measurement system is
ignited, the operating voltage is raised to 2.8 kV. After
successful ignition, this voltage then drops to 1.6 kV the-
reby increasing the useful service life of the measure-
ment system.
A status output indicates the two possible conditions of
the measurement system:
1. not ignited (including high tension OFF) and
2. ignited (and pressure > 3·10
-9 mbar).
A much improved ignition characteristic in the high vacu-
um range has been obtained through the special design
for the electrodes in the measurement system.
