Urdukas Combined wind speed-direction sensor

From 2004 to 2012 the AWS Urdukas station was equipped with the CombiSD DNA022 Lsi-Lastem combined wind speed-direction sensor, mounted on a 5m pole.

In 2013 this sensor was replaced with a Vaisala - Wind Set WA15.

Overview:

- high-performance wind measurement set;

- long and successful track record in meteorological applications;

- low measurement starting threshold;

- conical anemometer cups provide excellent linearity;

- heated shaft prevents bearings from freezing.

Technical Specifications

Wind Speed

- Sensor / transducer type: cup anemometer / opto-chopper

- Measurement range: 0.4...75 m/s

- Starting threshold: <0.5 m/s *

- Distance constant: 2.0 m

- Accuracy (range 0.4...60 m/s)

with characteristic transfer function: ±0.17 m/s **

with transfer function U=0.1xR: ±0.5 m/s

* Measured with cup wheel in position least favoured by flow direction. Optimum position gives approx. 0.35 m/s threshold.

** Standard deviation.

Wind Direction:

- Sensor / transducer type: vane / optical code disc

- Measurement range (wind speed 0.4...75 m/s):0...360°

- Starting threshold: <0.4 m/s

- Delay distance: 0.4 m

- Resolution: ±2.8°

- Accuracy: better than ±3°
