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°
