OTT HydroMet - Model LUFFT WS800-UMB -Smart Weather Sensor
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, solar radiation, lightning detection, air pressure, wind direction and wind speed. One external temperature sensor is connectable.
The robust and maintenance-free smart weather sensor WS800 is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.
Examples of use:
- Weather observation for road and traffic control systems
- Automatic weather station / Automatic weather sensor (AWS)
- PV-Monitoring / Solar Monitoring on photovoltaic farms
- Hydro-meteorological stations
- Weather observation for building automation
- Weather stations at airports, marinas and onboard ships
