Application
The M&C sample probes version SP3200V and
SP3200 are used for continuous ­ xtraction of
e
explosive gases (Ex-zone 2 or 22) from dust
loaden, high temperature and/or humid processes. The probes can be mounted in Ex-zone
2 or 22. Both versions differentiate only in the
sealing material of the filter housing. Version
SP3200V has got a sealing out of FPM for
types which are heated up to max.185°C
and version SP3200 has got a sealing out of
graphite for all versions heated up to more
than 185 °C.

For M&C probe version SP3200(V), the heaters
version HEX5-1.08 or HEX5-2.08 are available
as option (see Data sheet 2-3.1).

Description

The probe can be operated with both heating versions in Ex-zone 2 and 22 resp. Class I
Division 2, Groups A/B/C/D.

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, 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 ­ntegrity of the system.

Version HEX5-1.08 has got a temperature
controller integrated in the connection box
of the probe and is suitable for ambient temperatures up to 50°C. Version HEX 5-2.08 is
equipped with a temperature controller in a
wall mounting case to be mounted externally.
When using this combination, the probe can
be used at ambient temperatures up to 70°C
and the controller up to 50°C.

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 . 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.

The special design of the optional heating of the M&C-probes version SP3200(V)
permits controlled heating of the complete filter housing, including the mounting flange. This ensures reliable operation
e
­ xternal to the process preventing the
temperature ­ alling below the dew-point.
