Product Description

Lufft WS700 Compact Weather Station

All in one sensor.

Compact Weather Station for measuring of air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, air pressure, wind direction, wind Speed and radiation.

Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Precipitation is measured by a 24 GHz Doppler radar, which measures the drop speed of an individual drop of rain/snow. Precipitation quantity and intensity are calculated from the correlation between drop size and speed. The difference in drop speed determines the type of precipitation (rain/snow).

Ultrasonic technology is used for precise wind speed measurement, and is tested in a high-precision wind tunnel, so accuracy is guaranteed.

Measurement output can be accessed by the following protocols: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature sensor is connectable. Comes with a 10m cable.

Special features:

  • All in One
  • Aspirated temperature/humidity measurement
  • Maintenance-free operation
  • Open communication protocol:
  • UMB-ASCII, UMB-Binary, SDI-12, MODBUS, Analog outputs in combination with 8160.UDAC.
