Specification Brand : Zoeyilan BulletPoint1 : STRONG MATERIAL: The wind cup of the sensor is made of high-quality ABS material, providing excellent strength and durability. It operates efficiently even at low starting wind speeds. The material's superior erosion resistant ensures that the sensor remains and functional over time, even under harsh environmental conditions. BulletPoint2 : INTERFERENCE RESISTANT: The wind speed sensor is designed with a strong ability to other electrical interferences, ensuring accurate readings in various conditions. It is compact and lightweight, making it easy to carry, assemble, and install. This feature is particularly useful for outdoor and remote applications where electrical disturbances may be present. BulletPoint3 : TWO WIRING MODES: The wind speed sensor offers two wiring options: a bottom cable outlet and a side cable outlet. This flexibility allows for easier installation and adaptation to different setups, making it a versatile tool for various measurement needs. Whether it's for industrial, commercial, or outdoor use, the sensor is highly adaptable. BulletPoint4 : WEATHER RESISTANT: Designed to withstand a wide range of environmental conditions, the wind speed sensor is highly resistant to pressure, ensuring stable performance in extreme weather. Its wind resistant capabilities make it suitable for use in areas with strong winds, providing measurements even in harsh climates. BulletPoint5 : EXTENSION CABLE INCLUDED: The sensor comes with a 0.8-meter extension cable, providing flexibility in installation. The connection interface is designed with a sealing washer to ensure a waterproof seal, preventing water ingress and ensuring that the sensor functions properly in wet environments.
