2-1.3.9-ME Gas sampling and gas conditioning technology 5
6 APPLICATION
The probes of type SP3200V.. and SP3200.. are used for continuous gas sampling in dust-laden processes or
processes with high temperatures (according to table 5, chapter 10) or high gas moisture. The modular con-
struction of the probes and the variety of possible options guarantee optimum adaptation of the probes to
complex process and environmental conditions.
The probes of the type SP3200V.. and SP3200.. are available in both, an unheated and an electrically heated
version.
The probes must not be used for sampling of gases or gas mixtures that could be explosive,
even in absence of air or which change safety-relevant material properties. The gases or gas
mixtures must also not contain any solid particles that could generate ignitable friction or per-
cussion sparks in combination with the materials of the probe.
It is not allowed that during operation potential sources of ignition (e.g. smouldering or burn-
ing particles, glowing embers, foreign objects) are brought into the gas sample probe.

DESCRIPTION
The probes type SP3200(V).. have been designed for easy use, long life and uncomplicated service and
maintenance.
The internal filter element can be replaced without the need of tools or dismounting of the sample line. After
having removed the internal filter element, both the filter chamber and the sample tube can be cleaned easi-
ly.
SP3200V and SP3200 (combustible gases and dust):
The gas sample probes type SP3200V.. and SP3200.. are suitable for the sampling of gases and installation
in hazardous areas of zone 2 or 22 (combustible gases and dust). The only difference between both types is
the sealing material of the filter housing. Version SP3200 has got a filter housing sealing out of graphite for
special types which are heated above 185°C. Version SP3200V has got filter housing seals of Viton for special
types which are heated below or up to 185°C. The probe housing and all options are suitable for use in haz-
ardous areas of zone 2 or 22 (combustible gases and dust). Please read the identification in table 4.
The probe SP3200(V).. must not be used for gas sampling in zone 0/1.
The filter system of type SP3200(V).. is suitable for dusts of a fineness of up to 2 μm.
Behind the filtration, i.e. at the outlet of the gas sample probe, the sample gas is free of dust. This means that
in the absence of explosive sample gas downstream analysers can be used without any special protective
measures.
