D = Duct diameter
Installation requirements: The unit must not be installed in turbulent air zones.
Ensure sufficiently long settling zones upstream and downstream of the tapping
point. A settling zone consists of a straight section of pipe or duct with no
obstructions. Avoid installation near filters, cooling coils, fans, etc. The sensor
will achieve the optimal result when the measurement is taken at least 7,5 duct
diameters downstream and at least 3,5 duct diameters upstream from any turns
or flow obstructions.
ATTENTION
ATTENTION
Installation of the unit near high EMI-emitting devices may lead to faulty
measurements. Use shielded wiring in areas with high EMI.
ATTENTION
Keep at least 15 cm distance between the sensor lines and the 230 VAC power lines.
2.3
Install the probe at the desired depth, and in case you use the flange, fix it
via the plastic white screw in the flexible flange.
2.4
Unscrew the cover of the unit to remove it and insert the connecting cables
through the cable gland of the unit.
2.5
Do the wiring according to the wiring diagram (see
Fig. 4
) adhering to the
information from section
“Wiring and connections”
.

Close the enclosure and secure it with the screws. Tighten the cable gland to
retain the IP rating of the enclosure.
