Gauge Connector
TPS-compact is equipped with new generation
gauge reading card able to drive/read a Varian
"EyeSys Mini-IMG" gauge or a Varian Full Range
Gauge FRG-700.
The EyeSys Mini-IMG is a vacuum measurement
instrument based on the inverted magnetron ion
gauge design (see orderable parts table).
The gauge pressure operation range goes from
-3
-3
6.6x10
mbar [5x10
-9
[5x10
Torr] and its operation temperature range
goes from 0°C to 50°C [32°-122°F].
The FRG-700 Full Range Gauge is a combined
technologies gauge (Inverted Magnetron plus Pi-
rani Gauge).
FRG-700 measure from 5x10
-9
phere (3.8x10
Torr to atmosphere) and its tem-
perature range goes from 5°C to 55°C [41°-131°F].
Pressure data is available on three independent
reading channels:
1.
On-board display (data expressed in mbar,
Torr or Pa) – (see Pressure Display Module
picture)
2.
Serial communication line (Win 224)
3.
Analogical output.

Pressure gauge can be connected/disconnected
from the TPS-compact during normal operation.
The Mini-IMG gauge is intended for high vacuum
use, so with pressure above 50 mTorr the signal is
misinterpreted and a "false" pressure is displayed.
Use a transition gauge to understand if the reading
is really under 50 mTorr or not.
