INFICON PEG100 Medium to Ultra-High Vacuum Gauge - Manual (Page 12)

1. Table 1 has been included to clarify the relationship
between the output voltage and the pressure.
Note
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, correspon-
ding correction factors must be used which are available
from INFICON upon request.
2.2.4 Status Output
When the gauge is ready to measure, this is indicated
via the status output.
Status Status signal at Pin 6
(with respect to Pin 2)
————————————————————————
High voltage OFF
0 V
High voltage ON 0 V
(not yet ignited)
High voltage ON 0 V
at p < 3·10 -9 mbar
High voltage ON High (13.5 - 32 V, depending
at p > 3·10 -9 mbar on the supply voltage
(50 mA max.)
Note
When the pressure drops below 3·10
-9 mbar, the status
signal remains HIGH.
Caution FET output: The max. voltage is 42 V DC.
The max. load current is 100 mA DC.
Voltage output: Load current is 50 mA max.
When exceeding these maximum ratings
the PEG100 itself and/or any connected
equipment may be damaged.
When the PEG100 is ready to make measurements, the
FET is conductive. For this also refer to Section 2.3.2.
2.2.5 Identification
For the purpose of identifying the connected type of
gauge and the pressure range, the PEG100 is equipped
with an identification resistor (R = 100 k
Ω
) between Pin
4 and Pin 2. This resistor may be sensed by connected
operating or control units so that these can automatical-
ly adapt.
