[. . . ] www. vaisala. com WM30 Wind Sensor for Mobile Applications Flexible outputs A relay contact output is provided for wind speed. The wind speed can be recorded either by counting the number of pulses within a fixed time period, or by measuring the time between successive pulses. [. . . ] The electronics are located inside an anodized aluminium core which creates not only a firm body, but a watertight enclosure for the electronics as well. This provides full protection against water, dust, pollutants and electromagnetic interference. Accurate wind measurement The shape, dimensions, and material of the cups contribute to accurate measurement. The cups are carefully tested to give linear response between the wind speed and the angular velocity of the cup wheel. The wind vane is located directly beneath the cup assembly and is made of a durable, lightweight material that ensures fast response and low inertia. Easy installation A mast adapter for a 30 mm tube is supplied with the sensor. An installation kit for larger tube diameters, 50 . . . 110 mm, is available as an option.
