Product Description
compact housing
including fastening arm and connection cable
ETS product family: Physical sensors
Product type: Weather station
Intended Use
- Measurement and evaluation of weather data: wind speed, wind direction, precipitation, brightness, global radiation, twilight, temperature, relative air humidity and air pressure
- Installation on the outside of buildings, preferable in the roof and facade area
- Operation with additional power supply (ref.-no.: WSSV 10)
Characteristics
- Integrated GPS/GLONASS receiver for automated positioning
- Calculation of additional weather data: absolute air humidity, chill temperature, comfort
- Function for shading control
- Integrated KNX bus coupling unit
- Measuring and limit value monitoring
- Software logic modules for linking events
- Integrated heating
The weather station needs an operating voltage supply of 24 V AC, for example power supply module ref.-no. WSSV 10.
