Description
The
Rain/Wind Sensor KNX RW
measures precipitation and wind speed and trans-
fers the values to the KNX system. Four switching outputs with three adjustable thresh-
old values as well as additional AND and OR logic gates are available. The sensor sys-
tem, the evaluation electronics and the electronics of the bus connection are mounted
in a compact housing.
Functions:
•
Precipitation perception
: The surface of the sensor is heated so that only
drops and flakes are recognised as precipitation but not fog or dew. If it stops
raining or snowing, the sensor dries quickly and the precipitation message
ends
•
Wind measurement
: The wind strength measurement takes place
electronically and thus noiselessly and reliably, even during hail, snow and
sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of
the weather station are recorded
•
4 switching outputs (communication objects)
, 3 with adjustable
threshold values (Threshold values can be set by parameter or via
communication objects)
•
8 AND and 8 OR logic gates
with each 4 inputs. Every switching incident as
well as 8 logic inputs (in the form of communication objects) may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
Configuration is made using the KNX software ETS. The
