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, 21 and 22.

The sample probes are designed for easy installation, reliable operation and trouble- free 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, 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.
