PRODUCT DESCRIPTION
The RK120-01 combined wind speed and direction sensor is assembled with precision-machined ABS and aluminum alloy parts, offering high strength and easy installation. The wind speed section features a traditional three-cup design made of ABS material, delivering excellent starting performance, wide measurement range, superior linearity, and reliable stability. The wind direction section utilizes a low- inertia vane that responds instantly to wind changes. When wind direction shifts, the rear-mounted angle sensor detects azimuth changes and converts them into corresponding electrical signal variations, providing outstanding linearity, high accuracy, and full 360° coverage without blind spots.
