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, air pressure, wind direction, wind speed and radiation. One external temperature or rain sensor is connectable.

Advantages of the Smart Weather Sensor WS510:

  • Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
  • All-in-one housing concept of a compact weather sensor combining 6 measurement parameters in one housing with only one cable connection
  • First and only compact weather sensor with integrated Kipp & Zonen CMP10 Pyranometer with secondary standard quality
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • Compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol
  • Maintenance-free operation – no moving parts that can wear out
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
  • Ventilated temperature and humidity measurement according to WMO guidelines
  • Integrated heater that can be switched on if there is danger of frost

Application of the Smart Weather Sensor WS510:

The robust and maintenance-free smart weather sensor WS510 is designed for professional meteorological applications in all climate zones. It delivers reliable data, even in extreme ambient conditions.

  • PV-Monitoring / Solar Monitoring on photovoltaic farms
  • Automatic weather station (AWS)
  • Hydro-meteorological stations
  • Meteorological reference stations
  • Integration into various other systems/solutions, where this measurement parameters are needed…
