Wind direction and speed sensor (three-cup/vane type composite) with wind direction output 4-20mA type.
LSI Lastem
A measuring instrument that determines wind direction and wind speed by attaching three wind cups and a vane to a rotating vertical axis, and converting the rotation (wind speed) and position (wind direction) of the vertical axis through magnetic, electrical, or optical transformations.
● Composite type wind direction and speed sensor ● Easier to install than standalone sensors, can be easily mounted on a 5cm diameter pole ● Compact, lightweight, low-cost ● High durability limit wind speed of up to 75m/s (DNA121, DNA821.2) Composite type wind direction and speed sensor. The sensor incorporates transducers for both wind direction and wind speed, making it easier to install than separate sensor kits for each, while being small, lightweight, and low-cost. The accuracy and limit wind speed are comparable to using both a wind direction sensor and a wind speed sensor.
