Inficon PEG100 - Design and Function; Scope of Delivery

tina14e1-a (2017-12) PEG100.om 3
Based on a supply voltage of 24 V the PEG100 generates the internal supply vol-
tages required for operation of the integrated Penning measurement system. The
PEG100 supplies a logarithmic representation of the vacuum pressure by way of a
voltage signal which ranges 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 con-
trol voltage or by connecting an external switch.
When the gas discharge in the Penning measurement system is ignited, the oper-
ating voltage is raised to 2.8 kV. After successful ignition, this voltage then drops to
1.6 kV thereby increasing the useful service life of the Penning measurement
system.
A status output indicates the two possible conditions of the Penning 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 vacuum range has been ob-
tained through the special design for the electrodes in the measurement system.
