Application

The M&C sample probes version SP3100V and
SP3100 are used for continuous extraction of
explosive gases (Ex-zone 0, 1 and 2) from dust
loaden, high temperature and/or humid proc­esses. The probes can be mounted in Ex-zone
1, 2, 21 and 22. Both versions differentiate only
in the sealing material of the filter housing.
Version SP3100V has got a sealing out of FPM
for types which are heated up to max.185°C
and version SP3100 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 trouble­free maintenance. They are versatile in appli­cation and depending on the task to be per­formed, various pre-filters series V12 or V20
with integrated volume displacer, optional
with extension tubes (see page 4 and data
sheet 2-1.1.0.8), 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 ele­ment 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 with­out the use of tools. In this operation, neither
the sample probe tube nor the sample line
need to be removed, thus avoiding contami­nation 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 SP3100(V)
permits 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 SP3100(V) can be done by three dif­ferent 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 and 21, for gas sampling
from zone 0, 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 back-purging the M&C pre-filter, the
option RS is available with mounted buffer
vessel triggered by an explosion-proof sole­noid valve. 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.

When sampling from Ex-zones, back
purging is only allowed with a gas suit­able for the sampling point.
