The WS700 is a All in one sensor. It is a 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.

Model: 8380-U01

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). 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.

Lufft sensors, both in plastic and metal housing, use ultrasonic technology for precise wind speed measurement. Lufft sensors are tested in a high-precision wind tunnel, so accuracy is guaranteed.

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
