2 Application
The precipitation monitor transmits signals to determine the beginning and the end of precipitation
and the duration of the period of precipitation as required by meteorological services.
In addition, the precipitation monitor can be used to report status or to transmit control signals to
connected rain protection devices such as windows, air vents, awnings, or Venetian blinds.
3 Mode of Operation
Precipitation in the form of drizzle, rain, snow or hail is detected by means of a light barrier system
and triggers a signal. A built-in incidence-filter shall smooth the triggering of switching signals in
case of individual incidences, as for example leafs, bird droppings, insects etc. For this, a certain
number of at least n incidences should have occurred within a time-window of 50 sec. The number
of drop incidences (1…15) can be selected through the DIP-switch on the pc-board.
With the precipitation end the switching signal is reset after a selectable switch-off delay. Thanks to
the immediate evaluation of the incidences it is possible to determine precisely the beginning and
end of the precipitation period.
The instrument is equipped with a heating system for extreme weather condition. This avoids ice
and snow forming on the housing surface. In addition, the surface retains a temperature of >0° by
means of a regulated heating.
4 Installation
