Gas sampling and gas conditioning technology
2-1.1.5.1-ME
Insert the line through the corresponding opening in the bottom of the probe and
through the silicone retainer;
Connect the line to the tube joint. For Swagelok
®
-Fittings, the following is valid:
-
Put the line with supporting socket into tube joint until the limit stop;
Screw the union nut hand-tight;
-
Before drawing up, mark the union nut on the “6-a’clock position”;
-
Hold the body with a wrench and screw down the union nut by 1 ¼ rotations; after one entire
rotation, the marking has to be turned furthermore up to the “9-a’clock position”.
N O T E !
For the connection of tube lines to stainless steel tube joints, you
must always use a supporting socket.
Check the connection for tightness.
Place the probe cover again and shut it by both bent-lever closures.
13.1.2 CONNECTION OF THE BACKPURGE AND CALIBRATION GAS
W A R N I N G !
The back-purge pressure must always be higher than the process
pressure. The admissible maximum pressures must not be
exceeded (see technical data).
The return valve has got an opening pressure of 0,7bar.
VersionsSP2600-H/C/I/BB/F.. include separate connections for test gas feeding and back-purge gas
(see figure 1 and figure 2):
Back-purge gas for pipe Ø8 x 1mm, and
Calibration gas pipe socket Ø6 x 1mm.
The control of the stop valve /I is made separately within a pressure range of 3 to 10 bar. It is
equipped with a 6mm pipe socket.
13.2 ELECTRICAL CONNECTION
The temperature adjustment of probes type SP2600-H.. is effected with a capillary regulator as
standard. Optionally, the probe can be equipped with a PT100 or thermocouple. This requires the
connection of an external thermostat.
W A R N I N G !
Incorrect supply voltage may damage the device. When connecting
the equipment, please ensure that the supply voltage corresponds
to the information given on the type plate !
Please install the probes in such a way that any contact of the live
parts is impossible!
We recommend in any case to use heat-resistant cables !
The alarm contact for insufficient temperature must be monitored !
In case of a low temperature alarm (failure of the probe heating or
sensor), the gas sampling must be interrupted in order to avoid a
damage of the probe or downstream components.
