Product Description

Lufft WS301 Ultrasonic weather sensor with solar pyranometer
Lufft WS301 Ultrasonic weather sensor with solar pyranometer

For: air temperature / relative humidity / air pressure / solar radiation

Integrated design with ventilated radiation protection for measuring:
  • Air temperature
  • Relative humidity
  • Air pressure
  • Solar Radiation
Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Measurement data are available for further processing in the form of a standard protocol (Lufft-UMB protocol). Comes with 10m cable!

CMP3 Solar pyranometer. Aspirated temperature/ humidity measurement. Open communication protocol:
  • ASCII
  • UMB
  • SDI12
  • MODBUS RTU / MODBUS-ASCII
  • Analog outputs in combination with 8160-UDAC
Available with low-power setting for remote stations with solar power.
