Gas sampling and gas conditioning technology 2-1.1.7-ME
N O T E !
When using the heated sample pipe or pre-filter V12 in conjunction with
probes with the bypass return option ..BR, a short-circuit between the by-
pass gas and sample inlet in the centre of the probe flange must be pre-
vented or low sample gas readings will be obtained. Make sure that the gas-
ket for the mounting flange does not block the bypass return connection or
the probe will not function properly.

If the sample connection does not correspond with the flange connection DN65 PN6, the supplied
optional adapter flange must be fitted to the probe in the same way.

Position flange seal on sample connection.

Insert process-internal sample part of complete probe unit into sample connection.

Bolt mating and probe flange with supplied nuts and bolts.
N O T E !
For the preferred probe mounting position, the sample gas outlet points
downward (unnecessary for perfect functioning).
It is recommended to install the probe with a slight downward inclination
towards the process. This is essential for sampling, e.g. downstream of wet
scrubber (sample pipe type SP32), so that produced drops flow back into the
process.
13.2 CONNECTION OF DILUTED SAMPLE OUTLET TUBING
Provided on the probe side for connection of the sample outlet tubing is an elbow union with the di-
mension DN6/8mm (3/8“

o
for 115V version; optional also DN 8/10mm) in the space below the insu-
lating cover.
N O T E !
Excess backpressure on the sample outlet of the probe can result in poor
performance. The maximum recommended tube length for common inside
tube diameters are as follows:
Injector type I:

i
6mm max. 50m

i
8mm max. 150m
Injector type II:

i
8mm max. 15m

i
10mm max. 40m

i
12mm max. 80m
The sample tube is installed as follows:

Loosen toggle-type fasteners of insulating cover and remove the cover.

Insert tube through corresponding opening in base plate of the probe.

Connect tube to union.
N O T E !
When connecting hose pipes to stainless steel fittings, a supporting sleeve
must always be used.
The connection must be checked for tightness.

Refit probe cover and lock with toggle-type fasteners.
