Product Description

Lufft WS401 Weather Sensor, Tipping Bucket
WS-401
Integrated design with ventilated radiation protection for measuring:

  • Air temperature
  • Relative humidity
  • Precipitation
  • Air pressure
Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature.

Optionally, the Lufft WS401-UMB can be equipped with a leaf wetness sensor in addition. Precipitation is measured by tipping spoon and tipping bucket processes. The flexible tipping bucket allows a 0.2mm or a 0.5mm resolution of the rainfall.

Aspirated temperature/ humidity measurement. Open communication protocol:
  • ASCII
  • UMB
  • UMB-Binary
  • SDI12
  • MODBUS
  • Analog outputs in combination with 8160-UDAC
  • Comes with 10m cable
