Gas sampling and gas conditioning technology 2-1.1.6.1-ME

Now insert the process-internal probe section of the complete probe unit into the probe con-
nection, but first attach the flange seal to the probe connection and screw using the screws
and nuts supplied.
N O T E !
A preferred mounting position is to have the probe with its sample gas out-
let pointing downwards, although this is not absolutely necessary for per-
fect functioning. An advantage as well is mounting the probe with an angle
(10°) downwards.
12.1 PNEUMATIC CONNEXIONS

Remove the upper part of the sample line's mounting bracket and insert the sample line
through the silicon lid into the threaded pipe joint and connect it.

The temperature-resistant, stainless steel connectors supplied by M&C have a double ferrule
system to ensure reliable sealing. After tightening the nuts of these connectors by hand, they
should then be tightened exactly 1¼ of a turn using a flat spanner and are then properly
mounted.

If a PTFE tube is used as sample line, an insert must under all circumstances be inserted in
the end of the tube in order to prevent the tube being pressed together.

Screw on the upper part of the mounting bracket.

In the case of larger sample line diameters, it may be necessary for the central mounting of
the sample line to loosen the two screws and move the small mounting bracket of the mount-
ing bracket and then re-tighten them. Now place the heat conducting jaws around the sample
gas connection in the retaining slot and fix with the knurled nuts.
 Connect a tube ¼” at the check valve /C for calibration gas feeding and a tube 3/8” at the
backflush valve /BB or /BBF

Screw a suitable
stainless steel connector into the 1/8” NPT thread of the isolation valve /I
with pneumatic drive. The control line for operating the pneumatic drive has to be connected
to this stainless steel connector.

Now replace the protection shield and fasten using the pressure clamps.
