7 APPLICATION
The probes of the type SP3000 and SP3100.. are used for continuous gas sampling in dust-laden
processes or processes with high temperatures (per Table 7, chapter 10) or high gas moisture. The
modular construction of the probes and the variety of possible options guarantee optimum adaptation
of the probes to complex process and environmental conditions.
The probes of the type SP3000 and SP3100.. are available in both an unheated and an electrically
heated version.
The probes may not be used to withdraw gases or gas mixtures that can be
explosive even in the absence of air or which change safety-
relevant material
properties.
The gases or gas mixtures may also not contain any sol
id particles that could
generate ignitable friction or percussion sparks in combination with the materials
of the probe.
It is not allowed that during operation po
tential sources of ignition (e.g.
smouldering or burning particles, glowing embers, foreign
objects) are brought
into the gas sample probe.
8 DESCRIPTION
The probes of the type SP3000 and SP3100.. have been designed for easy use, long life and
uncomplicated service and maintenance.
The internal filter element can be replaced without the need for tools or dismounting of the sample line.
When the internal filter element has been removed, both the filter chamber and the sample tube can be
cleaned easily.
8.1 SP3000 (COMBUSTIBLE DUSTS)
The gas sample probes of the type SP3000 are suitable for gas sampling from potentially explosive
atmospheres in Zone 20 (combustible dusts). The probe housing and all options are designed for use
in potentially explosive atmospheres in Zone 1 or 21 (combustible dusts or combustible gases).
The markings can be found in the following table.

12 SP3000../SP3100.. | 1.00.02 www.mc-techgroup.com
The maximum surface temperature of the gas sample probe depends on the
process media temperature and the used options (blow back unit RS,
ball valve
drive MS1 and probe heating HEX4).
The permissible process media temperatures are not allowed to exceed 185 °C
[365 °F] at options 2-way-ball-valve VA and 3/2-way-ball-valv
e 3VA. For
variants without these last-mentioned options it is not allowed to exceed 200 °C
[392 °F]. The consequential maximum surface temperatures and the der
ivable
temperature classes of the gases are shown in Table 1.
The intended use limits the process media temperature and the choice of
options insofar as the maximum surface temperature has to be
below the limit
temperature of the flammable process dust mentioned in Table 7 resp. it
has to
correspond to the temperature class of the flammable process gases.

8.2 SP3100 (COMBUSTIBLE GASES)
The gas sample probes of the type SP3100 and SP3100V are suitable for gas sampling from potentially
explosive atmospheres in Zone 0 resp. 1 (combustible gases). They differentiate only in the material of
the gaskets for the filter housing.
The version SP3100 has a gasket out of graphite for probe types heated up to more than 185 °C
[365 °F]. The version SP3100V has a gasket out of Viton for probe types non-heated or heated up to
max. 185 °C [365 °F].
The probe housing and all options are designed for use in potentially explosive atmospheres in Zone 1
or 21 (combustible dusts or combustible gases). The markings can be found in the following table.
The maximum surface temperature of the gas sample probe is depending on
the process media
temperature and the used options (blow back unit RS, ball
valve drive MS1 and probe heating HEX4).
The permissible process media temperatures must not exceed 185 °C for the
options filter housing seal Viton®V, 2-way ball valve VA and 3/2-
way ball valve
3 VA. For variants without these last-
mentioned options, 200 °C must not be
exceeded. The resulting maximum surface temperatures and the resulting
temperature classes of the gases are shown in Table 2.
The intended use limits the process media
temperature and the choice of
options insofar as the maximum surface temperature has to be below the limit
temperature of the flammable process dust mentioned in Table 7 resp. it
has to
correspond to the temperature class of the flammable process gases.

This large filter element is made of stainless steel or a ceramic. The seals are made of graphite
or Viton. The housing is made of anodised aluminium.
The filter system is suitable for dusts with a fineness of up to 2 µm.
Behind the filter system, i.e. at the outlet of the gas sample probe, the sample gas is dust-free. This
means that in the absence of explosive sample gas downstream analysers can be used without any
special protective measures.
The following figure shows the basic version of the gas sample probe SP3000/SP3100(V).
Figure 1 Probes SP3000/3100(V) without options with preliminary filter type V20
The filter system of the gas sample probe SP3000 consists of a process-side preliminary filter and a
stainless steel filter element in the probe.
A preliminary filter from the table below must always be selected when using the probe at sampling
points with explosive atmosphere due to combustible dusts.

8.4 SAMPLE TUBES, PRE-FILTERS AND OPTION FW FOR SP3100
Warning
SP3100 and SP3100V:
If the gas-dust mixture that is to be examined can be cl
assified as potentially
explosive because it contains combustible gases, only downstream devices
(flowmeters, analyz
ers) with corresponding marking according to directive
2014/34/EU may be used.
Suitable explosion isolation with a flame arrester must be e
stablished. These
operating instructions do not cover any downstream units.
For probe SP3100 also option FW spun glass is available.
For option FW the filter element is dropped, and a spun glass cartridge is mounted at the filter housing
lid. This spun glass cartridge is filled with a high temperature resistant spun glass. The option FW is
used at sample points with risk of quickly blocking filter surfaces due to tar or sticky substances.
The use of standard filter elements S-3SS150 or S-2K150 is not possible with option FW.
When using the gas sample probe SP3100 and SP3100V at sampling points with explosive atmosphere
due to combustible gases, a preliminary filter can be dispensed with. In this case sample tubes
according to the following table can be selected.

9 OPTIONS
The following options 9.1 to 9.6 are available for use in potentially explosive atmospheres. Please see
Table 1 and Table 2 for the markings for the respective zones (combustible dusts and gases).
Warning
Attention must be paid to the operating parameters when selecting options.
9.1 BACK PURGING UNIT TYPE RS:
The back purging unit type RS consists of a pressure relief valve, solenoid valve, accumulator, and
patented pressure control valve in the probe outlet.
Warning
A back purging gas suitable for the sampling point must be selected for back
purging.
The back purging pressure m
ust always be higher than the process pressure.
This minimum pressure must be monitored at the inlet side of the accumulator
with a pressure monitoring switch. If the flush gas pressure drops below the
process pressure, the back purging solenoid valve may not be operated.
The maximum permissible pressures of 6 bar may not be exceeded (see
technical data, chapter 10).
Do not choose back flush intervals long
er than 3 seconds because in case of
strong pollution of the pre-filter p
ressure inside the probe would be rising and
than discharging to the analyzer via the patented
pressure control valve in the
outlet of the probe due to a defined leak rate of this valve.
At sampling points with inerting, back purging must be performed w
ith
corresponding inert gas. It must be ensured that the inert gas does not introduce
oxygen or combustible gases into the system.
The probe SP3100 and SP3100V with back purging
option may not be used for
gas sampling from Zone 0.
The cyclical operation of the solenoid valve and monitoring of the back purging pressure must be
effected externally. The electrical connection of the solenoid valve must be made in an Ex e connection
box.
9.2 OPTION 2-WAY BALL VALVE /VA
For any service work, e.g. changing the filter element or cleaning works, the stop valve in the probe
inlet is actuated from outside with the turning handle. This becomes necessary e.g. in case of
overpressure or in case of toxic gas components.
Danger
In case of toxic gas components, the probe must be flushed after shutting off and
before opening!

18 SP3000../SP3100.. | 1.00.02 www.mc-techgroup.com
9.3 OPTION /3VA FEEDING OF TEST GAS AND BACK PURGING VIA 3/2-WAY BALL VALVE
The 3/2-way ball valve allows both functions “back purging“ and “test gas feeding“ to be made
one after the other. Only one operation each can be automated via the pneumatic drive and must
be specified with the order.
This kind of gas feeding provides the advantage that during back purging the downstream analyse
system is automatically separated from the process, respectively, the probe is automatically separated
from the process during test gas feeding. For that reason, you need a lower quantity of test gas as no
mixture with the process gas may occur.
For measuring operation, turn ball valve into central position.
For blow back, turn ball valve into the corresponding position.
This means in case of manual operation to turn the handle from the central position to the left side up
to the stop.
For test gas feeding, the ball valve has to be turned to the right side up to the stop.
For measuring operation, return the ball valve into the central position.
Figure 2 Function schema of option 3/2-way ball valve /3VA
Warning
A back purging gas suitable for the sampling point must be selected for back
purging. At sampling points with inerting, back purging
must be performed with
corresponding inert gas. It must be ensured that the inert gas does not introduce
oxygen or combustible gases into the system.
The back purging
pressure must always be higher than the process pressure.
This minimum pressure must be monitored with a pressure
switch at the inlet
side of the accumulator or the check valve. If the flush gas pressure drops below
the process pressure, the back purging solenoid valve must not be operated.
The maximum permissible pressures of 6 bar
abs. must not be exceeded (see
technical data, chapter 10).
The probes SP3100
with blow back option or test gas option 3VA must not be
used for taking sample from zone 0.
