【Product Description】
The wind direction sensor manufactured by our company is a highly reliable, high-performancedevice. This series of sensors is capable of stably and accurately capturing ambient wind directionsignals, making it suitable for applications involving high-altitude operations, construction machinery
port equipment, and similar environments.The sensor features built-in digital circuitry designed to provide robust resistance against RFinterference, electromagnetic interference, and lightning-induced surges. The sensor's internal circuitrycaptures directional signals from the wind vane and outputs an electrical signal that bears a lineairelationship to the ambient wind direction.
The product boasts excellent water resistance and corrosion resistance; both its internalcomponents and rotating parts feature a sealed design that effectively prevents the ingress of watersalt spray, and dust. Furthermore, the unit incorporates buit-in temperature detection and heatingelements, enabling it to automatically activate or deactivate heating based on changes in ambienttemperature, thereby ensuring effective wind direction monitoring even in severe cold environments
