Description
The
Weather Station P04/3-RS485
measures temperature, wind speed, brightness
and it recognizes precipitation.
The weather station sends the currently recorded weather data, date and time once
every second. This data can be analyzed by an end device such as SPS, PC or MC. The
P04/3-RS485
has 2 connections for data output (A/B) and 2 for power supply (24 V
DC).
Functions:
•
Brightness measurement
with 3 separate sensors for east, south and west.
Recognition of twilight/dawn
•
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
