Analyzing System are achieved by paying attention to the following
points:
Make sure to install the probe in a suitable location where it will extract
the gas that is going to be tested.
The probe shall be fitted at least 10 pipe diameters after the outlet of the
engine, the turbocharger, or the last after-treatment device – choose which-
ever is further downstream. However, the probe shall also be placed at
least 0.5 m or 3 pipe diameters upstream from the exit of the exhaust gas
system – choose what provides the greatest length. See Figure 3-1 and
Figure 3-2
for the installation layout of the probe. If you find it difficult es-
timating where to install the probe, please contact Green Instruments A/S
for more instructions.
As a standard scope of supply, the analyzing board can be installed up to 3
m from the probe. If necessary, the umbilical cord can be extended.
