    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:
    • ASCII
    • UMB
    • SDI12
    • MODBUS RTU
    • Analog outputs in combination with 8160.UDAC
    • Comes with 10m cable

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