8 APPLICATION
The probes of type SP3110.. and SP3110V.. are used for continuous gas sampling in dust-laden
processes or processes with high temperatures (according to Table 5, chapter 13) 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 SP3110.. and SP311V.. are available in both, an unheated and an electrically
heated version.
The probes must not be used for sampling of gases or gas mixtures that could
be explosive, even in absence of air or which change safety-relevant material
properties. The gases or gas mixtures must also not contain any solid particles
that could generate ignitable friction or percussion sparks in combination with
the materials of the probe.
It is not allowed that during operation potential sources of ignition (e.g.
smouldering or burning particles, glowing embers, foreign objects) are brought
into the gas sample probe.
9 DESCRIPTION
The probes type SP3110(V).. have been designed for easy use, long life and uncomplicated service
and maintenance.
The internal filter element can be replaced without the need of tools or dismounting of the sample line.
After having removed the internal filter element, both the filter chamber and the sample tube can be
cleaned easily.
9.1 SP3110 AND SP3110V (COMBUSTIBLE GASES):
The gas sample probes type SP3110.. and SP3110V.. are suitable for the sampling of gases and
installation in hazardous areas of zone 1 (combustible gases). The only difference between both types
is the sealing material of the filter housing. Version SP3110 has got a filter housing sealing out of
graphite for special types which are heated above 185 °C [365 °F]. Version SP3110V has got filter
housing sealings of Viton®for special types which are heated below or up to 185 °C [365 °F]. The
probe housing and all options are suitable for use in hazardous areas of zone 1 (combustible gases).
Please read the identification in Table 4.
The filter system of type SP3110(V) is suitable for dusts with a fineness up to 2 µm.
After the filtration, i.e. at the outlet of the gas sample probe, the sample gas is free of dust. This means
that in the absence of explosive sample gas downstream analysers can be used without any special
protective measures.

www.mc-techgroup.com SP3110../SP3110V.. | 1.00.02 11
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 or HEX1). 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-valve 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
derivable 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 5 resp. it has to
correspond to the temperature class of the flammable process gases.

General safety instructions for back-purging and feeding of calibration gas
Warning
A back-purging gas suitable for the sampling point must be selected for back-
purging.
The back-purging pressure must always be higher than the process pressure.
This minimum pressure must be monitored with a press 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).
Do not choose back flush intervals longer than 3 seconds because in case of
strong pollution of the pre-filter pressure inside the probe would be rising and
then 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 with
corresponding inert gas. It must be ensured that the inert gas does not
introduce oxygen or combustible gases into the system.
10.1 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.
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. An additional solenoid valve in the sample gas outlet of the probe is not necessary
because the patented pressure control valve shuts the probe outlet during back-purging in order to
protect the downstream analysis against the pressure push of the back purge.
10.2 OPTION /R, /BB AND /BBF FOR FEEDING OF CALIBRATION GAS OR BACK-PURGING VIA
CHECK VALVE R 1/4“, BB 3/8“ OR BBF 3/8“:
For back-purging of the probe tube or the preliminary filter, flush gas is fed via the check valve.
Hereby, it is recommended to separate the downstream analysing system from the probe in order to
avoid pressure pushes to the system (Option /I). The opening pressure of the check valve is 0.7 bar.
The flush gas or calibration gas pressure should be higher than 0.7 bar.
Options /R and /BB are for backflush of the inside space of the probe and the preliminary filter, the
option BBF is for backflush of the probe filter and the preliminary filter.
Note
In order to avoid the cooling down of the inside probe, it is recommended to
effect the backflush in short intervals of < 1 s.
During the feeding of test gas, the analyze system remains connected. The quantity of test gas should
be at least 25 % higher than the quantity of measuring gas which is taken in by the analysing system,
thus avoiding a mixture with the test gas.

16 SP3110../SP3110V.. | 1.00.02 www.mc-techgroup.com
For processes with overpressure, this kind of feeding the test gas is not recommended. In this case,
you should use an integrated ball valve in the inlet of the probe as stop valve.
In principle, you need only a small quantity of test gas for probes with an integrated ball valve,
because the probe is separated from the process when the ball valve is activated so that there is no
danger of a mixture with the process gas.
In case of manual operation, please turn the turning handle to the right side until the limit stop in order
to shut off the probe.
Note
In case of low pressure operation, please take into consideration that as from
300 mbar secondary air will be taken in via the non-closed check valve.
10.3 OPTION /C/I FEEDING OF TEST GAS VIA CHECK VALVE BEHIND THE PROBE FILTER
WITH PNEUMATIC STOP VALVE FOR THE PROBE OUTLET TO THE PROCESS
By activating the pneumatic stop valve with compressed air, the measuring gas way behind the probe
filter is shut off. Now, you can feed test gas via the check valve to the sample gas outlet of the probe
without any loss.
10.4 OPTION 2-WAY BALL VALVE /VA
For any service work, eg. changing of the filter element or cleaning works, the stop valve in the probe
inlet is actuated from outside with the turning handle. This becomes necessary eg. in case of
overpressure or in case of toxic gas components.
Danger
In case of toxic gas components, the probe must be flushed after shut off and
before opening!
10.5 OPTION SPUN GLASS CARTRIDGE FW
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 soot or sticky substances.
The use of standard filter elements S-3SS150 or S-2K150 is not possible with option FW.
10.6 OPTION /3VA FEEDING OF TEST GAS AND BACK-PURGING VIA 3/2-WAY BALL VALVE
With the 3/2-way ball valve, you can execute both functions „back-purging“ and „test gas feeding“ one
after the other. Only one operation each may be automated via the pneumatic actuation.
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 the measuring operation, the ball valve must be put into the central position.
For back-purging, the ball valve must be put into the corresponding position.
This means in case of manual operation to turn the handle from the central position to the left side as
far as it will go.

www.mc-techgroup.com SP3110../SP3110V.. | 1.00.02 17
For the test gas feeding, the ball valve must be turned to the right side as far as it will go.
For the measuring operation, return the ball valve into the neutral position.
Figure 3 Function schema of option 3/2-way ball valve /3VA
Warning
For back-purge, a back-purge gas suitable for the sampling point must be
selected. At sampling points with inerting, the back-purging must be performed
with the appropriate inert gas. It is essential to prevent oxygen and flammable
gases from being introduced into the system by the inert gas.
The back-purge pressure and test gas pressure must always be higher than the
process pressure. This minimum pressure must be monitored on the inlet side
with a pressure switch. If the purging gas pressure drops below the process
pressure, the ball valve must not be operated.
The permissible maximum pressures of 6 bar abs. must not be exceeded (see
chapter 11 Technical data)
The probes SP3110 with back-purge option or test gas option 3VA must not be
used for gas sampling from zone 0.
