Combined Wind Speed and Direction Sensors

Combined anemometer and wind vane.

The WSD- series of wind speed and direction sensors accurately and reliably measure wind speed and wind direction in a single robust, compact meteorological grade instrument.

Features include:

  • Low inertial light metal anemometer
  • Intertia free wind vane
  • Analogue, 8-bit and serial synchron outputs available
  • Extra strong ship version available
  • Suitable for meteorological grade monitoring

Several options are available to suit every budget, measurement, and environment. Whether you want to acquire data from routine observations, need durability for ships at sea, or need research-grade data, we can offer a solution.  Contact us to discuss our range in detail.


ESS Earth Sciences supply and support a variety of combined wind speed and direction sensors. The WSD-Series combines an anemometer and wind vane in a single instrument. They are robust enough for gale-force winds at sea, but with the accuracy for meteorological research.

As we offer a large variety of wind speed and direction sensors we encourage you to contact us to discuss your requirements in detail. We can ensure your sensor will measure the correct ranges and provide the appropriate outputs. We will respond to all enquiries within 4 business hours.

Available ANEmometer and Wind Vane Ranges
  • 0.3 m/s to 50 m/s
  • 0.5 m/s to 75 m/s
  • 0.3 m/s to 60 m/s
  • All wind vanes measure a 0 to 360 degree range.

Our wind speed and direction sensors are available with a variety of outputs. It is possible to combined some outputs.

  • 3 to 1042 Hz
  • 5 to 745 Hz
  • 0 to 20 mA
  • 4 to 20 mA
  • 0 to 10 V
  • 0 to 5 V
  • 8-Bit Serial Synchron
  • 8- Bit Parallel

Metal is used for combined anemometers and wind vanes construction. Offering, reliability and longevity of life. Even more robust materials are used for versions designed for mounting on ships. This protects the instrument from the saltier environment and from damage due to exceptionally strong winds.

Anemometers are of a cupped design made from anodised aluminium. The wind vane bow is constructed of stainless steel.

Heating is available to guarantee the smooth running of the internal ball bearings in extremely cold environments.

How to mount WSD-Series sensor

Mount the wind speed and direction sensor to a mast or tube. The mast or tube must have an internal diameter of at least 40mm to allow cables to run down into it.
