Function and description
Sensor shelters are used to protect temperature and humid-
ity measuring instruments against unmeant in
fl
uences of the
weather when e
ff
ecting measurements in the open air.
Thus, the determined results of measurement are independent
of precipitation and their evaporation as well as of direct and
indirect radiation.
The measuring results are safe and will be comparable.
Constructionally sensor shelters are in such a way arranged
that the data acquisition area of the installed sensor are lo-
cated in the middle of the shelter.
Additionally the three upper lamellae are closed for thermal
insulation purpose. Thus optimal measuring conditions are
ensured.
The plastic lamellae are arranged in a de
fi
ned distance, one
above the other. By the special lamella design the protection of
the sensor against unmeant in
fl
uences is extremely e
ff
ective.
For improvement of ventilation the lowest lamella has a bigger
inner diameter of 73 mm. Furthermore the holder at this place
has special tapers and openings which optimise the ventilation
and prevent
fl
uid retentions.
The sensors are placed from below into the opening of the
shelter and
fi
xed by a clamping screw.
The clamp screw is placed inside the weather shelter which
causes a signi
fi
cantly improved stability of the complete shel-
ter (incl. sensor).
The sensor shelters can be installed on vertical and horizontal
masts or tubes.
