Roughing
system
7
In order to reduce the roughing time when
testing
large
volumes,
a
second
roughing pump can be added to the roughing system:
•
ASM 192
T
/

total capacity: 40
m

or 24 cfm.
•
ASM 192 TD+
/
192
T
2
D+
total capacity: 50
m
3
/h
or 36 cfm.
Apart from the roughing capacity, the weight and the power
consumption,
the
characteristics
and the
use
of the leak detector
remain the same.
Interface
board
8
The
helium leak
detector
can be equipped with a software version
which will offer a
complete RS
232 protocol:
•
3 operating modes: basic, advanced, printer;
•
possibility to
remote
control the
detector
(start/stop, autozero,
auto-cal
etc...);
•
possibility to obtain and adjust the settings;
•
possibility to obtain all the
maintenance
information for preventive
maintenance
purposes.
This RS
232 is the
most effective
interface to
supervise
your leak test
from a
PC
(data recording on an
Excel sheet,
for
instance)
and/or to
monitor the
detector
from a small PLC.

and 15 m (49 Ft).
Test
of gas
line
10
Used to perform spray
testing
on long lines (typical diameter
1
/4’
’),
with a reduced
response
time due to the
transfer
of the helium by
a
carrier gas injected in
viscous
flow
.
In this case, the
detector
is equipped with an additionnal
1/4”
VCR
connector
specific to this option.
Stainless steel
cover
(UCT)

Designed for
use
of the unit in clean rooms (“Ultra Clean
T
echnology”).
The
front and rear
covers
and frame are made of
stainless
steal.
