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
  • 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

 

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 and wind speed. One external temperature sensor is connectable.
