Gas sampling and gas conditioning technology 2-1.1.5-ME
 The nozzle mounting flange connection should be DN65 PN6 or 3“ANSI (115V version). For other
connection dimensions, an optional intermediate flange adapter is available. The necessary,
minimum flange sizes or minimal nozzle diameter depends on the sample tube used or the
preliminary filter diameter.

It is recommended to mount the probe horizontally with an angle of inclination of 10° with respect
to the process.
N O T E !
The suitability of the probe must be verified prior to installation by
comparison with the available operating parameters (see rating plate).
12 INSTALLATION
M&C SP2500-H.. probes are designed for stationary use and with correct selection of the sample point
and proper installation, they will give many years of trouble-free service with minimum maintenance.
12.1 PROBE ASSEMBLY

Remove the probe cover after opening the two toggle-type fasteners.

Place the flange gasket on the sample nozzle.

Bolt together the mounting support and probe flange with the supplied nuts and bolts.
When using the support tube adapter (for supporting the installation of long sample tubes or
preliminary filters when the probe is installed in a horizontal position), bolt the same between the
nozzle flange and special flange with the threaded bolts.
The supplied sliding segment must be screwed to the sample tube or extension tube of the preliminary
filter about 450mm away from the G3/4“t connecting thread.
If the sample nozzle does not correspond to the standard flange connection DN65 PN6, the optional
supplied adapter flange must be fitted to the probe in the same manner.
N O T E !
In the preferred probe mounting position, the sample gas outlet points
downwards (does not make any difference to the function of the probe).
It is recommended to mount the probe with a slight downward inclination
with respect to the process to enable any precipitated droplets to flow back
to the process.

Remove the heat conducting plates at the sample gas outlet after loosening the knurled screw.
For connection of the sample line, screw in an appropriately dimensioned union with 1/4"-NPT
connecting thread using PTFE sealing tape.
C A R E ! The fittings must be tightened carefully to avoid damaging the internal
components. The fittings must not be overtightened.
In the event of leaks, the fittings must not be tightened further. The
respective fitting should be removed completely and retightened.
Check unions for leaks.
