APPLICATION

The probes of type SP3110.. and SP3110V.. are used for continuous gas sampling in dust-laden
processes or processes with high temperatures (according to Table 5, chapter 13) or high gas
moisture. The modular construction 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 SP3110.. and SP311V.. 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 percussion sparks in combination with
the materials of the probe.
It is not allowed that during operation potential sources of ignition (e.g.
smouldering or burning particles, glowing embers, foreign objects) are brought
into the gas sample probe.

DESCRIPTION

The probes type SP3110(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 easily.

SP3110 AND SP3110V (COMBUSTIBLE GASES):

The gas sample probes type SP3110.. and SP3110V.. are suitable for the sampling of gases and
installation in hazardous areas of zone 1 (combustible gases). The only difference between both types
is the sealing material of the filter housing. Version SP3110 has got a filter housing sealing out of
graphite for special types which are heated above 185 °C [365 °F]. Version SP3110V has got filter
housing sealings of Viton
probe housing and all options are suitable for use in hazardous areas of zone 1 (combustible gases).
Please read the identification in Table 4.
The filter system of type SP3110(V) is suitable for dusts with a fineness up to 2 µm.
After 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.
