6 INTRODUCTION
M&C SP2500-H.. series probes are used for continuous gas sampling in dust-loaded processes at
high temperatures and high gas moisture.
The probe offers the possibility to remove the preliminary filter or sample tube in the process without
having to remove the probe head for cleaning purposes.
H/C/I/BB and ..-H/C/I/BB/F series probes are used in highly dust-loaded processes. The additionally
installed backflushing valve and pneumatic isolating valve in the sampled gas outlet ensure highly
efficient backflushing of the filter space in the in the probe head and used preliminary filter.
For further information or personal advice, please do not hesitate to contact us or visit us online to
view our wide range of products at:
7 DESCRIPTION
The probe has been designed for easy installation, safe operation, easy maintenance and diversity in
application.
Depending on the particular problem, various sample tubes or preliminary filters (see data sheets 2-
1.1.0.6 and 2-1.1.0.8), which are not included in the scope of supply of the probe, are screwed into the
G3/4"i thread in the filter holder.
The large, ceramic deep-bed filter element (optional glass fibre elements or glass wadding fillings
available) is arranged in a housing with minimal dead space outside the process area.
The probes are designed for replacement of the filter element without the need for tools; as the sample
line does not need to be removed, contamination of the clean gas side is avoided.
Cleaning of the sample tube or preliminary filter takes place by withdrawing the filter part from the
probe without having to remove the probe head.
Owing to the special design of the heating element of SP2500... series probes, the entire probe head
including mounting flange can be heated adjustable to 180°C, thus ensuring reliable operation without
cooling below the dew point externally. Temperature control with the standard version takes place by
means of an integrated capillary sensor thermostat with excess temperature limiter and alarm function
in a compact arrangement directly on the probe.
With the SP2500-H, backflushing or calibration gas supply takes place via an optional check valve
(option C).
Additional functions of the SP2500-H/C/I/BB(/F):
The calibration gas can be supplied directly at the check valve/C to the probe outlet.
Calibration gas supply at the probe is possible without any expensive gas loss via the
otherwise open probe inlet.
The isolating valve /I isolates the gas outlet of the heated filter chamber.
The filter space, sample tube or preliminary filter can be backflushed via the check valve /BB
projecting into the heated filter chamber.
The filter element, and via this indirectly, the filter space and sample tube or preliminary filter
can be backflushed via the check valve /BB/F installed in the heated chamber wall.

10 RECEIPT AND STORAGE
The probe and any special accessories should immediately be unpacked carefully upon delivery
and against the delivery note.
The delivery should be checked for any transport damage and the transport insurer immediately
notified of any damage.
11 INSTALLATION INFORMATION
When carrying out installation, the safety rules and regulations for the prevention of accidents must be
observed – this applies similarly to subsequent operation. The information in Chapter 3 “Important
safety information” must be observed in particular.
The following applies:
Select an optimal sample point according to the general guidelines or agree on a sample point
with the responsible authorities.
The sample point should be arranged so that sufficient space for installation and removal of the
probe is available; the insertion length of the sample tube should be taken into account.
Easy access to the probe must be ensured for any necessary maintenance.
The sample nozzle locally should be dimensioned so that the nozzle temperature is always above
the acid dew point to prevent corrosion and blockages.
If the ambient temperature in the area of the nozzle is higher than 60°C due to the radiated heat,
a radiant heat reflective plate must be installed in the area of the nozzle locally to protect the
probe.
Gas sampling and gas conditioning technology 2-1.1.5-ME
13
NOTE!
The suitability of the probe must be verified prior to installation by
comparison with the available operating parameters (see rating plate).
NOTE!
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.
CAR 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.
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.
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.
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.

NOTE!
When connecting hose assemblies to stainless steel unions, a supporting
sleeve must always be used.
The connection must be checked for leaks.
Push the filter housing cover with preliminary filter or sample tube into the filter space in the
probe head.
Swing clamp B to the right and with handle C bring eye bolt D in position E, so that the clamp
engages in eye bolt D and threaded bolt H; if necessary, push in or pull out the filter housing cover
slightly with the clamping screw A;
Turn handle C into position F and tighten handle A hand-tight by turning clockwise.
12.3 CONNECTION OF SAMPLE LINE
Provided on the probe side for connection of the sample line is a ¼“ NPTi thread. This thread can be
used for screwing in appropriate connecting unions for lines with the sizes Ø6mm (standard), 8mm or
10mm.
The sample line is connected as follows:
Loosen the toggle-type fasteners on the insulating cover and hood and remove.
Screw the appropriate threaded union into the probe head with sealing tape.
Insert the line through the respective opening in the probe base plate and silicone holder.
Connect the line to the union. For Swagelok® fittings:
- Fully insert the liner with support sleeve into the union.
- Tighten the union nut finger-tight.
- Prior to tightening, mark the union nut in the 6 o’clock position.
- Grip the body with a spanner and tighten the union nut with 11/4 turns; after a full turn, the mark
must be turned further to the 9 o’clock position.
Refit the special hood and close with clamps.

ATT E NTI ON!
The backflushing pressure must be higher than the process pressure.
Pay attention to the maximum pressure level (see technical data).
DANGER!
An incorrect system voltage can damage the device. Ensure that the
system voltage corresponds to the voltage shown on the rating plate
prior to connection!
The probes must be mounted so that any contact with live parts is
impossible!
The use of heat-resistance cable is recommended in any event!
The alarm contact excess temperature must be monitored!
In the event of an excess temperature alarm (failure of the probe
heating or sensor) the sample gas supply must be interrupted to
avoid damaging the probe or subsequent components.
NOTE!
For the erection of power installations with rated voltage up to 1000V,
the requirements of VDE 0100 as well as relevant standards and
specifications must be observed.
An external main switch must be provided.
The supply circuit of the device must be protected with a fuse
corresponding to the rated current (overvoltage protection); electrical
values are shown in the technical data.
When fitting a capillary or PID controller at the sample point, the
maximum permissible ambient temperature must be observed (see
8.). If this temperature is exceeded, a PID controller must be provided
externally and outside the temperature-critical zone.
12.4 CONNECTION OF BACKFLUSHING AND CALIBRATION GAS LINE
SP2500-H:
For option “C”, a check valve is fitted (see Figure 1, opening pressure 0.7bar). Connection of the
backflushing or calibration gas line takes place on the underside of the probe. Provided for this
purpose is a tube with the dimensions Ø8 x 1mm.
The connection for the optional second sample gas outlet is ¼“ NPTi. The thread is closed with a
cover.
SP2500-H/C/I/BB(/F):
In the versions SP2500-H/C/BB and SP2500-H/C/BB/F, separate connections are available for
calibration and backflushing gas (see Figures 2 and 3):
Backflushing gas tube connection Ø8 x 1mm, und
Calibration gas tube connection Ø6 x 1mm.
Control of the isolating valve I takes place separately within a pressure range of 3 to 10bar. This valve
has a 1/8“ NPTi connecting thread.
12.5 ELECTRICAL CONNECTION
Temperature adjustment of the SP2500-H/.. series probes generally takes place with a capillary
controller. The probe can also be provided with an optional PT100 or thermocouple. This requires the
connection of an external thermostat.

Prior to carrying out maintenance and repairs, the system and process-specific safety measures must
be observed.
Maintenance intervals cannot be recommended. These must be determined depending on the specific
application.
Maintenance of the probe is limited mainly to replacement of the filter mats and inspection of the seals

W ARN ING !
Prior to carrying out maintenance and repairs, it must be ensured
that no health-endangering contaminants remain in the probe. An
appropriate measure is to flush the probe with inert gas, for
example.
Before replacing the filter element, the sample gas supply must be
interrupted!
NOTE!
Graphite seals in combination with the highly heated probe can
only be used a single time. Important to note after fitting the filter
housing cover that the U-bolt is tightened hand-tight in a cold
condition and retightened when the operating temperature is
reached.
