Function and description
Sensor shelters are used to protect temperature and humid-
ity measuring instruments against unmeant influences of the
weather when effecting 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 defined distance, one
above the other. By the special lamella design the protection of
the sensor against unmeant influences is extremely effective.
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 fluid retentions.
The sensors are placed from below into the opening of the
shelter and fixed by a clamping screw.
The clamp screw is placed inside the weather shelter which
causes a significantly improved stability of the complete shel-
ter (incl. sensor).
The sensor shelters can be installed on vertical and horizontal
masts or tubes.

Cleaning of the sensor shelter
The cleaning of the shelter is very easy. It can be
done with common household detergents.
The shelter can be disassembled for this proce-
dure. For this the 4 upper screws just need to be
unscrewed and the lamellas need to be pulled up.
The lamellas can be cleaned with a wet cloth. After
cleaning the lamellas will be slipped onto the 4 pil-
lars and fixed with 4 screws.
Note: We recommend securing the screws
with locking varnish or something similar
after loosening them once.
Furthermore it is possible to clean the shelter (with-
out sensor) in a standard dishwasher. Due to our
experiences the hydrophobic features of the plastic
surface will be strengthened after the shelter was
cleaned inside a dishwasher.
