8 APPLICATION
The electrically heated M&C sample probe tube SP30-H../EX2 is used in extractive sampling systems
to avoid cooling and condensation of the sample in the insitu tube from the sample point to the heated
sample probe SP3200-H. It can be used for sampling from Ex-zone 2 and mounting in Ex-zone 2. To
avoid a premature demage by cooling and condenstaion in dust loaded processes, we recommend a
heated tube type SP30-H1.1-V/EX2, including an insitu pre-filter V20-2/30, heated up with the tube.
Hereby an early blocking or destruction is avoided.
9 DESCRIPTION
9.1 HEATED SAMPLE TUBE SP30-H../EX2 AND SP30-H1.1-V/EX2
N O T E !
The heated sample tubes SP30-H../EX2 and SP30-H1.1-V/EX2 can be
mounted in Ex-zone 2.
The electrically heated M&C sample tube SP30-H../EX2 is available in 0,6 m and 1,0 m, length (L1 in
Fig. 1 and 2). Other length on request.
With a mounting flange with 4 welded screws the heated sample tube SP30-H../EX2 can be easily
fixed both to the flange at the sample point and the probe head e.g. SP3200-H.
The heated sample tubes SP30-H../EX2 are equipped with a G3/4"i thread connector at the tube end.
This enables fixing a standard non heated sample tube or pre-filter to the heated insitu tube.
The electrical cartridge heater is located inside a double tube system, completely separated from the
process. At the version SP30-H1.1-V/EX2 the included large pre-filter V20-2/30 is heated up with the
sample tube.
The tube versions SP30-H../EX2 have an internal diameter of 22 mm.
The internal diameter of the version SP30-H1.1-V/EX2 is reduced to 6 mm to optimize the tube dead
volume.
The sample tubes SP30-H2/EX2 have a temperature sensor PT100 for max. 200 °C operating
temperature.
The sample tubes SP30-H1.1/EX2 and SP30-H1.1-V/EX2 have a temperature sensor Fe-CuNi for
max. 320 °C operating temperature.
