2 Application

The precipitation sensor serves as measuring instrument for the determination of the
instantaneous precipitation intensities (mm precipitation / min.). By integration of the
precipitation intensities, the precipitation quantity can be calculated, as well. Control- and
warning signals can be derived from the precipitation intensity.

The measuring signal is output as intensity-dependent analogue output value. The dimension
of the measurement value output is divided into 4 linear characteristic segments, which show a
tenth of the slope of the more sensitive segment.

Thus, it is possible to represent an intensity range from approx. 0,001mm/min. (light drizzle) up
to 10 mm/min. (extremely heavy rain) with reasonable resolution (quasi-logarithmic output).

3 Construction and Mode of Operation

Precipitation in the form of drizzle, rain, snow, or hail falls through a light band, induced by light
diodes, and lead to shadowing effects on the receiving side. The sent light is pulse-modulated
so that outside light effects cannot falsify the measurement results. From the extent of shading
along with the duration of falling through a factor is calculated that gives the information if
there is a precipitation incident or not.

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.

At the end of the precipitation the analogue output goes in one time of 180 sec.
(5.4103.20.041, 5.4103.20.741) or 50 sec. (5.4103.20.641) to 0 mA. If the precipitation starts,
the analog output rises again to the measured value.
