This RS485 Wind Speed Transmitter is a professional meteorological sensor designed to accurately measure horizontal wind speed in the range of 0 to 32.4 m/s. It features an integrated Hall sensor and is constructed using precision die-cast aluminum alloy, ensuring small dimension tolerance, high surface accuracy, and durability in harsh environments. The internal circuitry is fully protected for weather resistance, anti-corrosion, and waterproof performance, while the external connector uses a military-grade corrosion-resistant plug for extended product life.
The sensor adopts a low-inertia anemometer that efficiently converts wind into rotational motion, which is then translated into accurate digital signals via the internal Hall sensor. Its compact structure, ease of installation, and long transmission range make it suitable for a wide variety of applications including meteorology, environmental monitoring, oceanography, agriculture, transportation, and industrial automation.
