Product Description

WS501 UMB Compact Weather Station
Lufft WS501 Ultrasonic Weather Sensor with Solar Pyranometer

Measures air temperature / relative humidity / air pressure / wind speed / wind direction / solar radiation Integrated design with ventilated radiation protection for measuring:

  • Air temperature
  • Relative humidity
  • Air pressure
  • Wind direction
  • Wind speed
  • Solar Radiation
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).

CMP3 Solar pyranometer. Ultrasonic wind sensor. Maintenance-free operation. Open communication protocol:
  • UMB
  • SDI12
  • Analog outputs in combination with 8160-UDAC
  • Comes with 10m cable

Available with low-power setting for remote stations with solar power. Comes with 10m cable.
