DANGER
The Penning Gauge PEG100 may only be connected to supply units
or measuring instruments which meet the requirements of mains
isolated extra-low voltages (PELV) and VDE 0100.
The PEG100 is capable of operating off supply voltages ranging from 14.5 V to
36 V. A supply voltage of 24 V (dc) is recommended.
The power supply must be connected to Pin 1 (+) and Pin 2 (power supply ground).
The high voltage may be switched on either through Pin 7 using negative logic or
Pin 8 using positive logic.
In each case Pin 2 must be used as the reference potential.
Pin 7 switches the high voltage on when
• contact is established with Pin 2 or
• a voltage of less than 2.5 V is present with reference to Pin 2.
Pin 7 switches the high voltage off when
• there is no contact with Pin 2 (open input) or
• a voltage greater than 4 V is present with reference to Pin 2.
Pin 8 switches the high voltage on when
• contact is established with Pin 1 (supply voltage) or
• a voltage greater than 12 V is present with reference to Pin 2.
Pin 8 switches the high voltage off when
• there is no contact with Pin 1 (open input) or
• a voltage of less than 7 V is present with reference to Pin 2.
Operation of the PEG100 in the pressure range above 10
-2
mbar will cause the
accumulation of contaminations and will thus reduce service life. For this reason,
the high tension should only be switched on or off when the pressure has dropped
to the 10-2 to 10-3 mbar range.
The high tension may also be switched on or off directly by the output signal pro-
vided by a Pirani Standard Gauge with switching functions (e.g. PSG500-S). Thus
the PEG100 can be switched on or off automatically at a pressure of approximately
5×10
-3
mbar.
The PEG100 supplies a defined output signal ranging from 0.66 V to 10 V at Pin 3
with reference to Pin 5 which is signal ground. For this also refer to Table 1 in
Annex A.
Table 1 has been included to clarify the relationship between the output voltage
and the pressure.
The measurement signal provided by the PEG100 depends on the type of gas. The
values stated in Table 1 apply to nitrogen and air. For other gases, corresponding
correction factors must be used which are available from INFICON upon request.
