Application

The M&C sample probes version SP3000 are
used for continuous extraction of explosive
gases (Ex-zone 20, 21 and 22) from dust
loaden, high temperature and/or humid proc­esses. The probes can be mounted in Ex-zone
1, 2 or 21, 22.

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/V20 with
integrated volume displacer and 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. These
process-internal M&C pre-filters are necessary
for a valid Ex-approval of the M&C-probes
type SP3000. For error control of the pre-filter
the sample gas flow rate has to be monitored
externally.

The probe-internal M&C stainless steel 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 SP3000 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 of the M&C-probes version
SP3000 is controlled by a self-regulated heat­er version HEX4-135 or HEX4-180 (see data
sheet 2-3.2) for Ex-zone 1 and 21, temperature
class T4 resp. T3 and for gas sampling from
zone 0, 1 or 2. In dependence of the ambient
temperature and the heater version, the min.
temperature in the probe is 90°C resp. 120°C,
the max. temperature is 120°C resp. 160°C.

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 back­purging type RS, gas can be sampled from
zone 20, 21 and 22. 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.
