Wind Sensor WM30 Accurate wind speed and direction measurement all in one compact and economical instrument. ACCURATE WIND MEASUREMENT ACCURATE WIND MEASUREMENT Vaisala Wind Sensor WM30 is a compact and economical wind speed and direction sensor. The rotating cup anemometer at the top of the unit provides a linear response to wind speed. The vane, which is attached to the body of the unit, provides a fast response to wind direction. The shape, dimensions, and material of the cups all contribute to accurate, reliable measurements. The cups are carefully tested to give a 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. Features: Compact and light design is optimal for mobile applications Low power consumption Fast and linear response to wind Choice of one-wiper or two-wiper potentiometer models FLEXIBLE OUTPUTS 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. A potentiometer detects the position of the vane. The potentiometer features low starting and running torque, linear resistance, and long operation life. It has a single wiper with an open gap of fewer than 5 degrees. With constant voltage supplied to the potentiometer, the output voltage is directly proportional to the azimuth angle. DURABLE MATERIALS DURABLE MATERIALS The cups and vane are made of reinforced polyamide (PA) plastic which guarantees a rigid structure even at the highest wind speeds. The electronics are located inside an anodized aluminum 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. Industry Applications Meteorology Protect people and communities from the impacts of day-to-day and extreme weather with the industry's most accurate and reliable weather observation solutions.
