Gas sampling and gas conditioning technology 2-1.1.7-ME

Place the sampling point so that sufficient space is available for installation and removal of the
probe, taking into account the insertion length of the sample pipe.

Ensure good access to the probe for ease of maintenance.

Dimension the local sample connection so that the temperature of the connection is always above
the acid dew point to prevent corrosion and blockage problems. If this is not possible, a heated
sample pipe type SP35/SP30 is recommended for a cold orifice.

If the ambient temperature in the connection area is >60°C due to the radiated heat, a radiant heat
reflection plate must be provided locally for protection of the probe.
 The mounting flange connection of the orifice should be DN65 PN6 or 3“ANSI (115V version). For
other required connection dimensions, an optional adapter intermediate flange is available. In-
stead of fitting a flanged orifice, the probe can also be fitted with an available R2" connection
adapter to an appropriate pipe coupling connection. The necessary, minimum flange size or
minimum connection diameter depends on the sample pipe used or pre-filter diameter.

It is recommended to fit the probe horizontally with an angle of inclination of 10° towards the proc-
ess.
N O T E !
The probe must be checked for its suitability for use with the available oper-
ating parameters prior to installation (see type plate).
13 INSTALLATION
M&C SP2000H/DIL... probes are designed for stationary use. With correct selection of the sample
point and proper installation, they will give many years of service with minimum maintenance required.
13.1 INSTALLATION OF THE SAMPLE PROBE

Remove probe cover after opening two toggle-type fasteners.

Turn stirrup bolt at the top end of the filter holder several times anticlockwise until the retaining
bracket can be turned laterally to the left.

Remove filter holder from the probe and check that the filter element is screwed tight. Subse-
quently refit filter holder.

Bring retaining bracket into previous position and tighten stirrup bolt hand-tight.

Remove heat conducting plates at sample gas outlets after loosening knurled screw. For connec-
tion of the sample pipe, screw in an appropriately dimensioned pipe union with 1/4"-NPT threaded
connection using PTFE sealing tape.
N O T E !
Check pipe unions for tightness.

Screw supplied sample pipe or pre-filter directly or using an extension pipe into the 3/4" internal
thread in the probe flange with 3/4" flat gasket and tighten.
If the heated sample pipe type SP30/35 or ceramic pre-filter type V12 is used, the probe must be
bolted to its flange (with welded threaded studs). The flange seal must previously be placed be-
tween both flanges.
