MW 21 Combined Wind Sensor

• Combined wind sensor for wind speed and wind direction

• Easy to install

• Optical measuring principle with digital outputs

 



MW 21 Combined Wind Sensor integrates industrial class anemometer and wind vane sensors into one convenient instrument for accurate measurements of wind speed and direction. They use a digital optical measuring principle and are protected against inductive interference and static discharge. A 15 m cable with connector is supplied for easy installation.

The stainless steel bearings are sealed on both sides for a long and trouble-free life and the wind vane is balanced. MW 21 has a fast response due to the low mass anemometer cups and wind vane flag and is suitable for most industrial applications. The internal line drivers ensure correct operation when long cables up to 1000 m are used.
