Rain sensor RD2WI

Rain sensor

The Rain sensors determines whether it is raining, and does so virtually immediately. Any rain falls
on the Rain sensor's grid of gilded copper. Droplets of water conduct electricity between the grid's
contact lines. A resistance measurement is carried out to detect any droplets between the contact
lines. The Rain sensor is equipped with heating to prevent condensation and to dry any rain droplets
quickly.
The Rain sensor should preferably be mounted on the Meteorological station and connected to a
Priva process computer.
The Rain sensor indicates solely that it is raining, where relevant; it does not measure the
precipitation intensity. In addition, the sensor is less suitable for the identification of hail or
snow.

Mounting

1. Unscrew the two socket head screws (including clamping rings) on the underside of the Rain
sensor completely.
2. Guide the cable through the appropriate opening in the mast.
The Rain sensor has a set position on the mast.
3. Mount the Rain sensor with the two socket head screws (including clamping rings) on the support
of the mast.
4. Feed the cable through the hole in the clamp block assembly so that the cable re-emerges on
the underside of the block.
