The MW 21 combines an industrial class anemometer and wind vane sensor into one convenient instrument for accurate measurement of wind speed and direction. The MW 21 uses a digital optical measurement principle and is 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. 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 1,000 m are used.
