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.
