Gas sampling and gas conditioning technology
2-1.0-ME
Connection of the heated sample line:
Remove the heat-conducting shoes at the sample gas outlet after loosening the knurled-head
screw.
In order to connect the sample line, screw in a suitably sized threaded connector with a ¼"-
NPT connecting thread using PTFE sealing tape.
N O T E !
Make sure that the connection is leakproof !
Push the silicon cap onto the end of the heated sampling tube and introduce the tube
connection piece into the bolted pipe joint and connect.
If a PTFE tube is used as sample line, a carrying bracket must under all circumstances be
inserted in the end of the tube in order to prevent the tube being pressed together.
The temperature-resistant, stainless steel connectors supplied by M&C have a double-blade
ring 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.
Now place the red silicon heat insulation around the connection and push the mounting jaws
sideways onto the mounting disc and tighten with the knurled nuts.
Mounting of sample tube and adapter flange:
Screw either the probe tube directly into the ¾" inner thread in the flange of the probe with the ¾" flat
gasket and tighten.
If the heated probe tube type SP30/35 is used then the probe is to be screwed to their flange (with
welded threaded bolt). First insert the flange seal between the two flanges.
If the probe connection does not correspond to the standard flange connection DN65 PN6, then the
optionally supplied adapter flange should be mounted to the probe in the same way.
Now insert the process-internal probe section of the complete probe unit into the probe connection, 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 outlet
pointing downwards, although this is not absolutely necessary for perfect
functioning.
