Product Highlight:


WS501 Compact ultrasonic weather station with solar pyranometer for measuring air temperature, relative humidity, air pressure, wind speed, wind direction, solar radiation.

WS501 Ultrasonic weather station with solar pyranometer

air temperature / relative humidity / air pressure / wind speed / wind direction / solar radiation

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
  • Solar Radiation

Available with low-power setting for remote stations with solar power.

Measurement output can be accessed by the following protocols: ASCII, UMB, SDI12, MODBUS

Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Ultrasound sensor technology is used to take wind measurements. Measurement data are available for further processing in the form of a standard protocol (Lufft-UMB protocol).
