8 APPLICATION
The electrically heated sample tube SP30-H../EX2 is used wherever cooling down or falling below the
dew point, e.g. SP3200-H, is to be avoided during gas sampling from the sampling point to the heated
gas sampling probe.
In dust-laden processes which tend to fall below the dew point in the extraction area during operation or
when the system is at a standstill, it may be advisable to use the electrically heated sample tube SP30-
H1.1-V/EX2 with heated in-situ pre-filter V20-2/30. This prevents premature clogging or destruction.
9 DESCRIPTION
9.1 HEATED SAMPLE TUBE SP30-H../EX2 AND SP30-H1.1-V/EX2
The heated sample tubes SP30-H../EX2 and SP30-H1.1-V/EX2 can be
installed in hazardous areas of zone 2.
The electrically heated M&C sample tube SP30-H../EX2 is available in 0.6 m [23.62”] and 1 m (39.37“]
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.

www.mc-techgroup.com SP30-H../EX2 | 1.02.00 9
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-H1.1/EX2 and SP30-H1.1-V/EX2 have a temperature sensor Fe-CuNi for max.
320 °C [608 °F] operating temperature.

11 PREPARATION FOR INSTALLATION
Select the optimum sampling point according to the generally applicable guidelines or consult the
responsible authorities.
Locate the sampling point in such a way that there is adequate space for inserting and removing the
probe and pay attention to the insertion length of the probe tube.
Make certain that the probe is easily accessible so that you can carry out any subsequent maintenance
work without trouble.
If the ambient temperature in the area of the connections is > 70°C [> 158 °F] as a result of radiated
heat, then a radiated-heat deflector must be mounted to protect the probe.
The connection's mounting flange connection should comply with DN65 PN6. If other connection sizes
are required, the stud bolts of the heated sample tube can be arranged accordingly as option.
The necessary minimum flange size and the minimum connection diameter depends on the diameter of
the probe tube or pre-filter used.
Before mounting, the probe must be adjusted to the existing operating conditions.
The existing operational parameters are to be checked accordingly prior to commencing mounting work

13 ELECTRICAL CONNECTIONS
WARNI NG!
When connecting the equipment, please ensure that the supply
voltage is identical with the information provided on the model type
plate.
NOTE!
Attention must be paid to the requirements of IEC 364 (DIN VDE
0100) when setting high-power electrical units with nominal voltages
of up to 1000 V, together with the associated standards and
stipulations.
In any case we recommend the use of temperature resistant cable!
A main switch and matching fuse must be provided externally!
The main circuit must be equipped with a fuse corresponding to the
nominal current (over current protection); for electrical details see
technical data.
It is recommended to use the low temperature alarm. In case of an
alarm the flow can be stopped and the components downstream the
probe are safe for demage.
Function and correctness of the temperature control (temperature
class) is in the sole responsibility of the installer and operator.

13.1 ELECTRICAL CONNECTION OF THE HEATED SAMPLE TUBE
WARNING!
The used cables for the connection of the heating must have an
outer diameter of 6-12 mm corresponding to the clamping range of
the cable glands!
W ARNING!
The max. admissible ambient temperature for the connection box
of the sample tubes SP30-H../EX2 and SP30-H1.1-V/EX2 is +70 °C
[158 °F].
Temperature resistant cable have to be used corresponding to the
max. temperature at the installation site.
•Remove lid of the connection box. In the lid there is also the electrical wiring plan.
•Insert the power cable (min. 3 x 1.5 mm2) coming from the external temperature controller
through the cable gland and connect it at the corresponding terminals 6, 7 and 8.
•Insert the temperature sensor cable through the other cable gland and connect it to the terminals
2, 3 and 4.
•Remount lid.
Function and correctness of the temperature control (temperature
class) is in the sole responsibility of the installer and operator.

14 STARTING
WARNI NG!
Before starting up check whether the mains power supply voltage
corresponds with the information stated on the nameplate.
WARNI NG!
Start up only the built-in heated probe tube because otherwise
there is a risk of burning!
WARNI NG!
Check whether the housing of the heating controller and the
connection box of the heated sample tube are earthed. Earth
resistance < 0.3 Ohm.
•Switch on mains power supply.
•Then inner temperature of the sample tube has to be measured during the heat-up phase.
The maximum temperature reached is the value for the temperature class. This has to be taken
from the table below. Adjust desired temperature via controller.
Function and correctness of the temperature control (temperature
class) is in the sole responsibility of the installer and operator.
•The nameplate contains no information about the temperature class because this is determined
by the temperature controller only.

15 MAINTENANCE
W ARNING!
The safety instructions specific to the plant and process are to be
consulted prior to any maintenance work!
DANGER!
Caution, danger of explosion!
Under voltage do not take the device off the mains!
WARNI NG!
When working during operation:
High surface temperatures!
Touching the surfaces can result in burns. Wear protective gloves
and protect against unauthorized access!
WARNI NG!
Work on the gas sample probe may only be carried out when the
environment has beendeclared an explosion-free zone, i.e. it is free
of explosive atmospheres.
The requirements of VDE 0100 and its associated standards and
regulations must be observed when erecting and servicing high-
voltage power installations with rated voltages to 1000V!
16 CLEANING
NOTE!
In case of external contamination of the connection box and the
temperature controller housing clean these onlywith a clothwetted
with soapy water.
