Special Features
Gas Sample Probe Series SP®
Version SP3110V and SP3110 for sampling from
zones with explosive gas with different options
for calibration gas feeding, back purging and
shut-off
SP3110V/RS/HEX4-135 resp. 180
Application
The M&C sample probes version SP3110V and
SP3110 are used for continuous extraction of
explosive gases (Ex-zone 1 and 2) from dust
loaden, high temperature and/or humid proc-
esses. The probes can be mounted in Ex-zone
1, 2 or 21, 22. Both versions differentiate only
in the sealing material of the filter housing.
Version SP3110V has got a sealing out of FPM
for types which are heated up to max.185°C
and version SP3110 has got a sealing out of
graphite for all versions heated up to more
than 185 °C.
Description
The sample probes are designed for easy
installation, reliable operation and trouble-
free maintenance. They are versatile in appli-
cation and depending on the task to be per-
formed, various pre-filters series V12 or V20
with integrated volume displacer, optional
with extension tubes, not included in the
scale of delivery, can be simply screwed into
the mounting flange of the basic probe. For
error control the sample gas flow rate has to
be monitored externally.
This M&C stainless steel or ceramic filter ele-
ment with a large surface and high capacity
is located in the external housing. The design
offers little or no stagnant space outside
the process. The probe housing is covered
with a protection shield which is part of the
Ex-approval.
The probes are designed in such a way that
changing the filter element is possible with-
out the use of tools. In this operation, neither
the sample probe tube nor the sample line
need to be removed, thus avoiding contami-
nation of the clean gas path and maintaining
the integrity of the system.
The special design of the optional heating
of the M&C-probes version SP3110(V) per-
mits controlled heating of the complete filter
housing, including the mounting flange. This
ensures reliable operation external to the
process preventing the temperature falling
below the dew-point.
The temperature control of the M&C-probes
version SP3110(V) can be done by three dif-
ferent heater types.
The first possibility is a self-regulating heater
version HEX4-135 or HEX4-180 (see data sheet
2-3.2) for Ex-zone 1 or 21, for gas sampling
from zone 1 or 2. In dependence on the
ambient temperature and the heater type,
the min. temperature in the probe is 90°C
resp. 120°C, the max. temperature is 120°C
resp. 160°C.
The second possibility is a controlled heating
version HEX1-3 for Ex-zone 1, adjustable up
to 180 °C and for sampling from Ex-zone 1 or
2. The controller has to be mounted outside
the Ex-zone.
The third possibility is a controlled heating
version HEX1-1 for Ex-zone 1, adjustable up
to 180 °C and for sampling from Ex-zone 1 or
2. The controller can be mounted inside the
Ex-zone.
For calibration gas feeding or back-purging
different options are possible. For example
the option RS with mounted buffer vessel
triggered by an explosion-proof solenoid
valve is available . With the mounted option
for back-purging type RS, gas can be sampled
from zone 1 and 2. The back-purge pressure
has to be monitored externally and has to be
min. 1 bar higher than the process pressure.
For the pressure control while back-purging,
a corresponding special valve is mounted
in the sample gas outlet. Thus an additional
solenoid valve to shut off the sample gas
outlet is not necessary. The back purge inlet is
shut off by a check valve.
