    WS502 Temp, Humidity, Radiation, Air Pressure, Wind

    Item No: 8375_U10

    Product Description

    WS502 Temp, Humidity, Radiation, Air Pressure, Wind
    Lufft WS502 Ultrasonic weather sensor, electronic compass

    For: Temperature, Relative Humidity, Radiation, Air Pressure, Wind, Electronic Compass

    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. Ultrasonic 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).
    All in One / Aspirated temperature/humidity measurement. Open communication protocol:
    • UMB-ASCII
    • UMB-Binary
    • SDI-12
    • MODBUS
    • Analog outputs in combination with 8160.UDAC
    • Third-Party-Rain gauge sensors are compatible: 0.1 mm, 0.2 mm, 0.5 mm, 1mm heated and unheated.
    One external temperature or rain sensor is connectable. Comes with 10m cable.
