    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).

    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.
