Key features
- Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
- All-in-one housing concept of a compact weather sensor combining 7 measurement parameters in one housing with only one cable connection
- Built-in data pre-processing, universal interfaces and selectable output protocols
- Maintenance-free operation – no moving parts that can wear out
- Compatible with many commercially available Met/HydroMet data loggers and PLS systems thanks to an open communication protocol
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
- Ventilated temperature and humidity detection
- Integrated heater that can be switched on if there is danger of frost
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, air pressure, wind direction, wind speed and radiation. One external temperature sensor is connectable.
