Sensor Shelter (8141.62)

Function and description

Sensor shelters are used to protect temperature and humid-
ity measuring instruments against unmeant infl uences of the
weather when eff 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.
(8141.62) Sensor Shelter
 natural ventilation of the sensors
 improved lamellar system
 suitable protection against direct and
indirect radiation
 protection against weather infl uences
 simple mounting on pipes
Additionally the three upper lamellae are closed for thermal
insulation purpose. Thus optimal measuring conditions are
ensured.
The plastic lamellae are arranged in a defi ned distance, one
above the other. By the special lamella design the protection of
the sensor against unmeant infl uences is extremely eff 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 signifi cantly improved stability of the complete shel-
ter (incl. sensor).
The sensor shelters can be installed on vertical and horizontal
masts or tubes.
