- Non-Contact Operation: Ultrasonic anemometers have no moving parts, ensuring minimal maintenance and long service life.
- High Precision: Provides inertia-free, highly responsive measurements ideal for capturing sudden wind gusts and peak values.
- All-Weather Performance: Features like automatic heating prevent icing, enabling reliable operation in snow, ice rain, and high-alpine/offshore environments.
- Multi-Parameter Measurement: Simultaneously measures wind speed, wind direction, and virtual (air) temperature.
- Flexible Outputs: Supports integration via analog outputs (e.g., 4–20 mA) and digital interfaces for seamless connection to weather stations and data loggers.
- Remote Wind Profiling: LiDAR technology enables vertical wind profiling and wide-area wind assessment, especially useful for offshore wind farms.

WIND SENSORS
WIND MEASUREMENT DONE BY STATE-OF-THE-ART TECHNOLOGY
The measurement of the wind speed and wind direction are regarded as elemental meteorological parameters. As a producer of automatic weather stations, company SOMMER has gathered a vast experience in wind measurement and cooperates with wind sensor producers of worldwide leading format.
PRODUCT VARIATIONS
- Wind sensor 05103 (white) with output of wind speed and direction as frequency and potentiometer
- Wind sensor 05103 (black) – heavy duty – with reinforced bearing and special black coating against icing
- Wind sensor 05103L with Linedriver and output of wind speed and direction as 4 … 20 mA signal
WIND SENSOR 263
Combined, light and compact anemometer to measure wind speed and wind direction.
- Light and compact design of high quality and reliability
- Cup anemometer made from CFK secures highly sensible response (CFK = carbon fibre reinforced plastic)
- Wind vane mechanical damping
- Electronics saved with rough and fine protection against overvoltage
ULTRASONIC ANEMOMETER 2D
The ultrasonic anemometer 2D is used for the two dimensional recording of horizontal components of wind speed and wind direction as well as the virtual-temperature. Due to the high measuring rate the device is qualified for inertia free measuring of wind squalls and peaks.
The accuracy of measuring the air temperature (virtual-temperature) surpasses the classical systems, where a temperature sensor is used in a weather and radiation shelter. The measuring results are transmitted via analogue signals or as data telegram over a serial interface. Optionally there is the possibility that the sensor as well as the device body is heated at critical surrounding temperatures automatically. Therefore, the operation is secured also at snowfall and ice rain conditions. Furthermore, icing of the sensor is prevented. There is practically no maintenance needed due to the non-contact ultrasonic measurement technique.
- Ultrasonic Anemometers:
- Measure wind speed and direction using ultrasonic pulses between transducers.
- No moving parts → minimal maintenance and fast, inertia-free response to gusts and turbulence.
- LiDAR (Light Detection and Ranging):
- Uses laser beams and the Doppler effect to measure wind speeds at multiple heights.
- Ideal for wind energy resource assessment without needing tall met masts.
- SODAR (Sonic Detection and Ranging):
- Uses sound waves to determine vertical wind profiles by analyzing backscattered signals.
- Cost-effective alternative to LiDAR for many applications.
- Heated Anemometers:
- Mechanical cup or propeller sensors equipped with automatic heating.
- Ensures reliable operation in icing, snow, or extreme cold conditions.
